Food Irradiation: An Effective Technique To Improve Food Safety

What is Food Irradiation?

It is a technique where foods are exposed to ionizing radiation to destroy microorganisms, bacteria, viruses, or insects that might be present in or on the food. The technique uses gamma rays (from cobalt-60 or cesium-137), X-rays, or electron beams from a machine source to blast foods with ionizing energy, altering their molecular structure. History

The concept of food irradiation was first researched as early as the beginning of the 20th century. However, it gained global recognition around the 1950s when serious research was performed to establish its viability and commercial applications. Initial research showed irradiation could effectively eliminate bacteria from meats and spices without changing their visual appearance and quality. The first international conference on food irradiation took place in 1956. Since then, many countries approved irradiation of various food items like spices, herbs, onions, potatoes, fruits, and meats. How Does Irradiation Work? Here's a brief overview of how irradiation works: - Radiation sources like gamma rays or electron beams are used to generate the required radiation energy. - Food Irradiation Food items are placed on a conveyor belt or rack and passed through the radiation area at a controlled dose rate and exposure time. - The radiation energy penetrates through packaging and food physically altering DNA/RNA structures of microbes present. - At approved low doses, it does not make food radioactive but disrupts cellular functions and DNA/RNA structure of pathogens and insects, preventing their reproduction. - The end result is elimination or reduction of pathogens and insects without altering the visual or sensory qualities of foods. Advantages of Food Irradiation Reduces Foodborne Illnesses: Irradiation is extremely effective in eliminating pathogens that cause serious foodborne illnesses. It can destroy bacteria like E. coli, Listeria, Salmonella and other parasites in meat, poultry, seafood and spices. This significantly improves food safety. Lengthens Shelf Life: By halting microbial growth and arresting ripening/sprouting processes, irradiation extends the refrigerated shelf life of various produce and foods by several weeks. This reduces spoilage losses during storage and transportation. Controls Insect Infestation: Low dose irradiation is approved globally to control insect pests in grains, cereals, dried fruits and herbs. This eliminates quarantine issues and reduces post-harvest losses from insects and insect-borne diseases. Maintains Sensory Qualities: When performed at approved low doses, irradiation does not alter the appearance, texture, aroma or flavor of foods. Irradiated fruits and vegetables look and taste fresh for much longer. Sanitizes Spices: Many spices are irradiated to kill Salmonella, E. coli and other pathogens that may be present naturally or from cross-contamination during processing. This eliminates food safety risks from consuming contaminated spices. Applications of Food Irradiation Fruits & Vegetables: Irradiation preserves the quality and extends shelf life of several delicate produce including mangoes, papayas, potatoes, onions and garlic by 3-4 weeks. It arrests ripening/sprouting to prevent losses during storage and transport. Poultry: The poultry industry uses irradiation to destroy Campylobacter and Salmonella bacteria routinely present in raw chicken and turkey. This significantly reduces the risk of foodborne illnesses from consuming undercooked poultry meat. Spices: Many commonly used herbs and spices like black pepper, cumin, coriander, basil, celery are irradiated to kill pathogens and insects. It ensures the microbial safety of spices. Grains: Low dose irradiation is used globally to control insect pests in grains like wheat, rice and pulses. This eliminates quarantine issues and reduces post-harvest losses during transportation and storage.

Control Program Requirements for Fermented Meat Products

The producer must have a program in place to assess the incoming product. This program should outline specifications for the incoming ingredients. This may include criteria including receiving temperature, farm/ supplier, lot code or packed on date, species/cut etc.

2. Facility and Equipment Requirements

Equipment used in the fermentation process must be included in the operator's prerequisite control programs. These must include the following elements:

Temperature in the fermentation, drying and smoking chambers must be uniform and controlled to prevent any fluctuation that could impact on the safety of the final product.

Fermentation, drying and smoking chambers must be equipped with a shatter resistant indicating thermometer, (or equivalent), with graduations of 1°C or less. If mercury thermometers are used, their mercury columns must be free from separations. All thermometers must be located such that they can be easily read.

Fermentation and smoking chambers must be equipped with a recording thermometer for determining degree-hours calculations in a reliable manner. Recording thermometers are also preferable in drying and aging rooms but, in these rooms, it may be sufficient to read and record the temperatures 2 times a day.

Drying and aging rooms must be equipped with humidity recorders in order to prevent uncontrolled fluctuations of the relative humidity. The only alternative to an automatic humidity recorder in these rooms would be for the company to manually monitor and record ambient humidity twice a day (morning and afternoon) every day with a properly calibrated portable humidity recorder.

For routine monitoring, accurate measurement electronic pH meters (± 0.05 units) should be employed. It is important that the manufacturer's instructions for use, maintenance and calibration of the instrument as well as recommended sample preparation and testing be followed.

When the aw of a product is a critical limit set out in the HACCP plan for a meat product, accurate measurement devices must be employed. It is important that the manufacturer's instructions for use, maintenance and calibration of the instrument be followed.

3. Starter Culture

The operator must use a CFIA approved starter culture. This includes Freeze-dried commercially available culture as well as back-slopping (use of previously successful fermented meat used to inoculate a new batch). When performing back-slopping, the operator must have a control program in place to prevent the transmission of pathogens from when using the inoculum from a previous batch to initiate the fermentation process of a new batch. These must include:

The storage temperature must be maintained at 4°C or less and a pH of 5.3 or less.

Samples for microbiological analysis must be taken to ensure that the process is in line with the specifications.

The frequency of sampling is to be adjusted according to compliance to specifications.

Any batch of inoculum which has a pH greater than 5.3 must be analysed to detect at least Staphylococcus aureus. Only upon satisfactory results will this inoculum be permitted for use in back slopping.

This can be an expensive and a time exhaustive process and is generally avoided due to food safety concerns. AHS does not allow back-slopping.

[Chef WK was in communication with the U of A to get his method, a starter mix, studied.]

4. Chemical Acidification

If product is chemically acidified by addition of citric acid, glucono-delta-lactone or another chemical agent approved for this purpose, controls must be in place and records kept to ensure that a pH of 5.3 or lower is achieved by the end of the fermentation process. These acids are encapsulated in different coatings that melt at specific temperatures, which then release the powdered acids into the meat batter and directly chemically acidulate the protein.

Summer sausage is a very common chemically acidified product. The flavor profile tends to be monotone and lacking depth. 

5. Water Activity Critical Limits

The aw may be reduced by adding solutes (salt, sugar) or removing moisture.

Approximate minimum levels of aw (if considered alone) for the growth of:

molds: 0.61 to 0.96

yeasts: 0.62 to 0.90

bacteria: 0.86 to 0.97

Clostridium botulinum: 0.95 to 0.97

Clostridium perfringens: 0.95

Enterobacteriaceae: 0.94 to 0.97

Pseudomonas fluorescens: 0.97

Salmonella: 0.92 - 0.95

Staphylococcus aureus: 0.86

parasites: Trichinella spiralis will survive at an aw of 0.93 but is destroyed at an aw of 0.85 or less.

The above levels are based on the absence of other inhibitory effects such as nitrite, competitive growth, sub-optimum temperatures, etc., which may be present in meat products. In normal conditions, Staphylococcus aureus enterotoxins are not produced below aw 0.86, although in vacuum packed products this is unlikely below aw 0.89.

6. Time and Temperature for Fermented Products

Certain strains of the bacteria Staphylococcus aureus are capable of producing a highly heat stable toxin that causes illness in humans. Above a critical temperature of 15.6°C, Staphylococcus aureus multiplication and toxin production can take place. Once a pH of 5.3 is reached, Staphylococcus aureus multiplication and toxin production are stopped.

Degree-hours are the product of time as measured in hours at a particular temperature multiplied by the "degrees" measured in excess of 15.6°C (the critical temperature for growth of Staphylococcus aureus). Degree-hours are calculated for each temperature used in the process. The limitation of the number of degree-hours depends upon the highest temperature in the fermentation process prior to the time that a pH of 5.3 or less is attained.

The operator is encouraged to measure temperatures at the surface of the product. Where this is not possible, the operator should utilize fermentation room temperatures. The degree hour calculations are based on fermentation room temperatures. Temperature and humidity should be uniform throughout the fermentation room.

A process can be judged as acceptable provided the product consistently reaches a pH of 5.3 using:

fewer than 665 degree-hours when the highest fermentation temperature is less than 33°C;

fewer than 555 degree-hours when the highest fermentation temperature is between 33° and 37°C; and

fewer than 500 degree-hours when the highest fermentation temperature is greater than 37°C.

This means that as the temperature increases, the amount of time that you have available to reach 5.3 or under is shorter. The warmer the temperature, the sharper the log growth phase of bacteria, which equates to more overshoot in lactic acid production, faster.

8. Examples of Degree-hours at constant room temperatures

Example 1:

Fermentation room temperature is a constant 26°C. It takes 55 hours for the pH to reach 5.3.

Degrees above 15.6°C: 26°C - 15.6°C = 10.4°C Hours to reach pH of 5.3: 55 Degree-hours calculation: (10.4°C) x (55) = 572 degree-hours

The corresponding degree-hours limit (less than 33°C) is 665 degree-hours.

Conclusion: Example 1 meets the guideline because its degree-hours are less than the limit.

Example 2:

Fermentation room temperature is a constant 35°C. It takes 40 hours for the pH to reach 5.3.

Degrees above 15.6°C: 35°C - 15.6°C = 19.4°C Hours to reach pH of 5.3: 40 Degree-hours calculation: (19.4°C) x (40) = 776 degree-hours

The corresponding degree-hours limit (between 33 and 37°C) is 555 degree-hours.

Conclusion: Example 2 does not meet the guideline because its degree-hours exceed the limit

9. Fermentation Done at Different Temperatures

When the fermentation takes place at various temperatures, each temperature step in the process is analyzed for the number of degree-hours it contributes. The degree-hours limit for the entire fermentation process is based on the highest temperature reached during fermentation.

Example 1:

It takes 35 hours for product to reach a pH of 5.3 or less. Fermentation room temperature is 24°C for the first 10 hours, 30°C for second 10 hours and 35°C for the final 15 hours.

Step 1

Degrees above 15.6°C: 24°C - 15.6°C = 8.4°C Hours to reach pH of 5.3: 10 Degree-hours calculation: (8.4°C) x (10) = 84 degree-hours

Step 2

Degrees above 15.6°C: 30°C - 15.6°C = 14.4°C Hours to reach pH of 5.3: 10 Degree-hours calculation: (14.4°C) x (10) = 144 degree-hours

Step 3

Degrees above 15.6°C: 35°C - 15.6°C = 19.4°C Hours to reach pH of 5.3: 15 Degree-hours calculation: (19.4°C) x (15) = 291 degree-hours

Degree-hours calculation for the entire fermentation process = 84 + 144 + 291 = 519

The highest temperature reached = 35°C

The corresponding degree-hour limit = 555 (between 33°C and 37°C)Conclusion: Example 1 meets the guideline because its degree-hours are less than the limit.

10. Fermentation done at Different temperatures

Example 2:

It takes 38 hours for product to reach a pH of 5.3 or less. Fermentation room temperature is 24°C for the first 10 hours, 30°C for the second 10 hours and 37°C for the final 18 hours.

Step 1

Degrees above 15.6°C: 24°C - 15.6°C = 8.4°C Hours to reach pH of 5.3: 10 Degree-hours calculation: (8.4°C) x (10) = 84 degree-hours

Step 2

Degrees above 15.6°C: 30°C - 15.6°C = 14.4°C Hours to reach pH of 5.3: 10 Degree-hours calculation: (14.4°C) x (10) = 144 degree-hours

Step 3

Degrees above 15.6°C: 37°C - 15.6°C = 21.4°C Hours to reach pH of 5.3: 18 Degree-hours calculation: (21.4°C) x (18) = 385.2 degree-hours

Degree-hours calculation for the entire fermentation process = 84 + 144 + 385.2 = 613.2

The highest temperature reached = 37°C

The corresponding degree-hour limit = 555 (between 33°C and 37°C)

Conclusion: Example 2 does not meet the guidelines because its degree-hours exceed the limit.

11. What happens if fermentation fails to hit critical limit?

What happens if the batch takes longer than degree-hours allows? For restaurant level production, it's always safer to discard the product. The toxin that Staph. Aureus produces is heat stable and cannot be cooked to deactivate. In large facilities that produce substantial batches, the operator must notify the CFIA of each case where degree-hours limits have been exceeded. Such lots must be held and samples of product submitted for microbiological laboratory examination after the drying period has been completed. Analyses should be done for Staphylococcus aureus and its enterotoxin, and for principal pathogens, such as E. coli O157:H7, Salmonella, and Clostridium botulinum and Listeria monocytogenes.

If the bacteriological evaluation proves that there are fewer than 104 Staphylococcus aureus per gram and that no enterotoxin or other pathogens are detected, then the product may be sold provided that it is labelled as requiring refrigeration.

In the case of a Staphylococcus aureus level higher than 104 per gram with no enterotoxin present the product may be used in the production of a cooked product but only if the heating process achieves full lethality applicable to the meat product.

In the case where Staphylococcus aureus enterotoxin is detected in the product the product must be destroyed.

12. E. coli and Salmonella Control in Fermented Sausages

Business' that manufacture fermented sausages are required to control for verotoxinogenic E. coli including E. coli O157:H7 and Salmonella when they make this type of product. This includes:

establishments which use beef as an ingredient in a dry or semi-dry fermented meat sausage;

establishments which store or handle uncooked beef on site;

Establishments which do not use beef and do not obtain meat ingredients from establishments which handle beef are not currently required to use one of the five options for the control of E. coli O157:H7 in dry/semi-dry fermented sausages. 

Any processed RTE product containing beef or processed in a facility that also processed beef, must be subjected to a heat treatment step to control E. coli O157:H7. Heating to an internal temperature of 71°C for 15 seconds or other treatment to achieve a 5D reduction is necessary. This is a CFIA requirement and is not negotiable.

Uncooked air dried products produced as RTE, must meet shelf stable requirements as detailed for Fermented-Dry products.

13. Options for E. coli validation

Without lab testing, the two main methods of validation are with heat treating by either low temp and a long duration, or various hotter processing temperatures for a shorter timeframe.

A challenge study to validate a process can take 1 year and over $100,000!

14. Option1; Heating

15. Option 2; pH, heating, holding, diameter

16. Safety and consistency

The aw and pH values are critical in the control of pathogens as well as to ensure shelf-stability in all semi-dry and dry fermented meat products. Each batch must be tested for aw and/or pH in order to verify that the critical limits are met.

Although aw measurement is mandatory only for shelf stable products, it is strongly recommended that the producer determine the aw values achieved for each product type they manufacture and for each product. Once this has been established, frequent regular checks should be made to ensure consistency. In the U.S., they rely on moisture to protein ratio and have set targets. This lab-tested value is a direct correlation of the % water to % meat protein and not aw. This gives more consistency to common names. For example, to legally call a product "jerky" it must have a MPR of 0.75:1 or lower. Remember your ABCs:

Always be compliant.

Before you can sanitize a surface, you first need to make sure it’s properly cleaned.

Start by using a surface cleaner or surfactant to remove any visible dirt, grease, or organic matter from the area. It’s important to do this cleaning step thoroughly, as any leftover debris can protect microbes from the sanitizing agent.

Once the surface is visibly clean, you’ll need to rinse it well with clean water to wash away any residual cleaner.

Now that the surface is clean and rinsed, you can move on to the sanitizing step. What I do in my workspaces, is: a diluted bleach solution (10% bleach to 90% water) or other applicable sanitizer to spray or wipe down the area. This kills off most bacteria and viruses that could contaminate your reesesech.

Something to consider that many dont realize: you should allow the sanitized surface to fully air dry before using it. Wiping it down could reintroduce contamination and beach, for wxample, has an ancillary disinfection that occurs drom its fumes as it dries ;).

Worth considering: there will be some disconnect between people considering this due to sanitization, sterilization, disinfection, aseptic, etc all kinda mixing together.

Aseptic technique is essentially “maintaining an environment that does not introduce microbes onto a workspace”.

Sanitization and disinfection are, imo, same coin but sanitization is of a lesser degree of microbial reduction. More appropriate for getting a workspace clean enough to run a food manufacturing process-line.

Disinfection is the next step up, requiring more concentrate strength in solution used and kills more shit. Sterilization is more like … autoclave.

“Bleach is a strong and effective disinfectant – its active ingredient sodium hypochlorite is effective in killing bacteria, fungi and viruses, including influenza virus – but it is easily inactivated by organic material. Diluted household bleach disinfects within 10–60 minutes contact time (see Table G.1 below for concentrations and contact times), is widely available at a low cost, and is recommended for surface disinfection in health-care facilities. However, bleach irritates mucous membranes, the skin and the airways; decomposes under heat and light; and reacts easily with other chemicals. Therefore, bleach should be used with caution; ventilation should be adequate and consistent with relevant occupational health and safety guidance. Improper use of bleach, including deviation from recommended dilutions (either stronger or weaker), may reduce its effectiveness for disinfection and can injure health-care workers.“

Photosynthesis is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism. Photosynthesis usually refers to oxygenic photosynthesis, a process that produces oxygen. Photosynthetic organisms store the chemical energy so produced within intracellular organic compounds (compounds containing carbon) like sugars, glycogen, cellulose and starches. To use this stored chemical energy, an organism's cells metabolize the organic compounds through cellular respiration. Photosynthesis plays a critical role in producing and maintaining the oxygen content of the Earth's atmosphere, and it supplies most of the biological energy necessary for complex life on Earth.

Some bacteria also perform anoxygenic photosynthesis, which uses bacteriochlorophyll to split hydrogen sulfide as a reductant instead of water, producing sulfur instead of oxygen. Archaea such as Halobacterium also perform a type of non-carbon-fixing anoxygenic photosynthesis, where the simpler photopigment retinal and its microbial rhodopsin derivatives are used to absorb green light and power proton pumps to directly synthesize adenosine triphosphate (ATP), the "energy currency" of cells. Such archaeal photosynthesis might have been the earliest form of photosynthesis that evolved on Earth, as far back as the Paleoarchean, preceding that of cyanobacteria (see Purple Earth hypothesis).

While the details may differ between species, the process always begins when light energy is absorbed by the reaction centers, proteins that contain photosynthetic pigments or chromophores. In plants, these proteins are chlorophylls (a porphyrin derivative that absorbs the red and blue spectrums of light, thus reflecting green) held inside chloroplasts, abundant in leaf cells. In bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas. The hydrogen freed by the splitting of water is used in the creation of two important molecules that participate in energetic processes: reduced nicotinamide adenine dinucleotide phosphate (NADPH) and ATP.

In plants, algae, and cyanobacteria, sugars are synthesized by a subsequent sequence of light-independent reactions called the Calvin cycle. In this process, atmospheric carbon dioxide is incorporated into already existing organic compounds, such as ribulose bisphosphate (RuBP). Using the ATP and NADPH produced by the light-dependent reactions, the resulting compounds are then reduced and removed to form further carbohydrates, such as glucose. In other bacteria, different mechanisms like the reverse Krebs cycle are used to achieve the same end.

The first photosynthetic organisms probably evolved early in the evolutionary history of life using reducing agents such as hydrogen or hydrogen sulfide, rather than water, as sources of electrons. Cyanobacteria appeared later; the excess oxygen they produced contributed directly to the oxygenation of the Earth, which rendered the evolution of complex life possible. The average rate of energy captured by global photosynthesis is approximately 130 terawatts, which is about eight times the total power consumption of human civilization. Photosynthetic organisms also convert around 100–115 billion tons (91–104 Pg petagrams, or a billion metric tons), of carbon into biomass per year. Photosynthesis was discovered in 1779 by Jan Ingenhousz. He showed that plants need light, not just air, soil, and water.

Photosynthesis is vital for climate processes, as it captures carbon dioxide from the air and binds it into plants, harvested produce and soil. Cereals alone are estimated to bind 3,825 Tg or 3.825 Pg of carbon dioxide every year, i.e. 3.825 billion metric tons.

That reminds me of the Krebs cycle, which creates ATP instead of using it. I am learning just how much lifeforms rely on each other to survive. Destroying one could cause many others to crumble. Interesting.

(OOC: Sorry, but I do not understand plants very well at all. I like anatomy of animals, humans, and bugs more).

In a world teeming with microbial assailants, the quintessence of human ingenuity has manifested in a simple, elegant solution: vaccines. These minute miracles, conjured through the alchemy of modern science, have transcended the mundane and achieved the extraordinary, transforming our collective fate.

Vaccines, the stalwart sentinels of our immune system, have unequivocally altered the trajectory of human health. They have extirpated smallpox from the annals of endemic diseases and relegated polio to the brink of oblivion. Their efficacy is not merely anecdotal but robustly corroborated by empirical data. Consider the paradigm of the measles vaccine: a triumph that has diminished the global incidence of this virulent scourge by 99% since its inception. Such statistics are not mere happenstance but the result of meticulous research and rigorous clinical trials, which have consistently demonstrated the unparalleled efficacy of vaccines.

The statistics delineating the benefits of vaccination are irrefutable. The World Health Organization (WHO) attests that vaccines prevent 2-3 million deaths annually. The historical reduction in morbidity and mortality rates from diseases such as diphtheria, tetanus, and pertussis is a testament to their unparalleled potency. Moreover, the introduction of the human papillomavirus (HPV) vaccine has precipitated a precipitous decline in the prevalence of HPV-related cancers, illustrating the prophylactic prowess of vaccination.

Yet, in an era rife with misinformation, the discourse surrounding vaccines is often obfuscated by fallacious narratives. The specter of adverse reactions is frequently invoked by detractors, yet the preponderance of evidence elucidates that such occurrences are exceedingly rare. The incidence of severe allergic reactions, anaphylaxis, is approximately 1 in a million. By contrast, the morbidity and mortality associated with vaccine-preventable diseases are exponentially higher. The juxtaposition of these statistics underscores the irrefutable verity that the benefits of vaccination overwhelmingly eclipse the infinitesimal risk of adverse effects.

To deny the efficacy of vaccines is to eschew reason and embrace anachronism. It is to dismiss the incontrovertible evidence amassed through decades of scientific inquiry.

Photosynthesis is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism. Photosynthesis usually refers to oxygenic photosynthesis, a process that produces oxygen. Photosynthetic organisms store the chemical energy so produced within intracellular organic compounds (compounds containing carbon) like sugars, glycogen, cellulose and starches. To use this stored chemical energy, an organism's cells metabolize the organic compounds through cellular respiration. Photosynthesis plays a critical role in producing and maintaining the oxygen content of the Earth's atmosphere, and it supplies most of the biological energy necessary for complex life on Earth.

Some bacteria also perform anoxygenic photosynthesis, which uses bacteriochlorophyll to split hydrogen sulfide as a reductant instead of water, producing sulfur instead of oxygen. Archaea such as Halobacterium also perform a type of non-carbon-fixing anoxygenic photosynthesis, where the simpler photopigment retinal and its microbial rhodopsin derivatives are used to absorb green light and power proton pumps to directly synthesize adenosine triphosphate (ATP), the "energy currency" of cells. Such archaeal photosynthesis might have been the earliest form of photosynthesis that evolved on Earth, as far back as the Paleoarchean, preceding that of cyanobacteria (see Purple Earth hypothesis).

While the details may differ between species, the process always begins when light energy is absorbed by the reaction centers, proteins that contain photosynthetic pigments or chromophores. In plants, these proteins are chlorophylls (a porphyrin derivative that absorbs the red and blue spectrums of light, thus reflecting green) held inside chloroplasts, abundant in leaf cells. In bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas. The hydrogen freed by the splitting of water is used in the creation of two important molecules that participate in energetic processes: reduced nicotinamide adenine dinucleotide phosphate (NADPH) and ATP.

In plants, algae, and cyanobacteria, sugars are synthesized by a subsequent sequence of light-independent reactions called the Calvin cycle. In this process, atmospheric carbon dioxide is incorporated into already existing organic compounds, such as ribulose bisphosphate (RuBP). Using the ATP and NADPH produced by the light-dependent reactions, the resulting compounds are then reduced and removed to form further carbohydrates, such as glucose. In other bacteria, different mechanisms like the reverse Krebs cycle are used to achieve the same end.

The first photosynthetic organisms probably evolved early in the evolutionary history of life using reducing agents such as hydrogen or hydrogen sulfide, rather than water, as sources of electrons. Cyanobacteria appeared later; the excess oxygen they produced contributed directly to the oxygenation of the Earth, which rendered the evolution of complex life possible. The average rate of energy captured by global photosynthesis is approximately 130 terawatts, which is about eight times the total power consumption of human civilization. Photosynthetic organisms also convert around 100–115 billion tons (91–104 Pg petagrams, or a billion metric tons), of carbon into biomass per year. Photosynthesis was discovered in 1779 by Jan Ingenhousz. He showed that plants need light, not just air, soil, and water.

Photosynthesis is vital for climate processes, as it captures carbon dioxide from the air and binds it into plants, harvested produce and soil. Cereals alone are estimated to bind 3,825 Tg or 3.825 Pg of carbon dioxide every year, i.e. 3.825 billion metric tons.

Why are we suddenly in a science lesson? Its interesting nontheless though!

Bed and Sleeping pad Guide

In the event that you find you are not sleeping great it could be because of an old and uncomfortable bed. How long we spend in bed can influence its solidness. Assuming the sleeping pad is uneven and the springs are too fun it very well may be an ideal opportunity to go out to shop. We additionally change as we age. An individual who has once dozed best on a delicate sleeping cushion might be more suited to a harder sleeping pad further down the road, or, the other way around. Weight gain and weight reduction can all impact how we respond to our beddings. A sleeping pad may be ideally suited for one individual however in the event that two people begin utilizing it there could be troubles. Studies visit site here have demonstrated the way that beds can lose up to 70% of their unique solidness more than 10 years.

How Would I Choose a Sleeping pad? Prior to looking for a bedding you really want to arm yourself with relevant data. First figure out what type of bed is best for you. Do you like delicate or hard beds? Could you prefer a standard bedding or a froth sleeping pad? In the event that you are don't know, go evaluate one or two bedding types. Second, think about your spending plan. This isn't a buy you need to ration, as an unfortunate night's sleep can influence your entire day. Attempt to get as much worth as possible for your financial plan. At last, size is a vital variable particularly in the event that there is more than one individual sleeping in the bed. Preferably, you ought to both have the option to lie on the bed with your arms behind your heads and not touch. A bed should be 10-15 cm longer than the tallest individual sleeping in that bed. Likewise focus on the level. Lower beds can be not difficult to get into however more earnestly to escape. High beds can be difficult to get into, particularly for more diminutive people, yet extremely simple to jump out of toward the beginning of the day.

The Outside of a Sleeping pad The sleeping pad outside is called ticking. Outwardly it is truly not excessively important to choose a "pretty" sleeping cushion as it will be covered more often than not. Rather you need to ensure the ticking is durable and all around made and not inclined to tearing. The better ticking is made of material that is sewn or woven utilizing cotton or thick yarn. Less expensive beddings are made of polypropylene or polyester. The least expensive sleeping cushions are made of stitchbond or fortified material. Producers currently make outer sleeping cushion covers with extraordinary features like enemy of sensitivity, hostile to bacterial and against static. They might be impervious to staining, water and fire. Incredibly enough, there are even beddings that emit various fragrances helpful for a decent night's sleep.

Spring Sleeping pads There are three essential types of spring sleeping cushions. A consistent spring sleeping cushion is produced using a solitary piece of wire woven into many springs. The springs are connected in an upward design. The wire is delicate and the curls are small. This produces additional response from the sleeping pad. An open curl sleeping pad is the most widely recognized type of bedding. The springs are organized evenly and associated at their tops and on the base by a bending wire. The poles that go around the edge of the loops add strength. A pocket spring sleeping cushion has curls that are set in fabric covers. Rather than working as a unit, these springs function independently. Accordingly development between accomplices on a similar bed can not be felt by the other.

Froth Sleeping cushions Plastic froth sleeping cushions are very responsive as they are really produced using elastic tree sap. Known for their solidness, they additionally have hostile to sensitivity and against microbial attributes. These sleeping cushions return to their unique shape when you get off the bed. Pressure is uniformly appropriated as well. A thick versatile or adaptive padding bed is made of polyurethane froth. It doesn't answer as fast as a plastic froth sleeping cushion yet is superb at easing pressure focuses on the body. This froth sleeping cushion has a few unique densities making some harder than others. Polyurethane froth beds are petrol based. They too come in various densities and are one of the more popular froth beds.

The Benefits of Using Soil Conditioner for Healthy Crop Growth

Soil conditioners play a crucial role in enhancing soil quality and promoting healthy crop growth. These products, which can be organic or synthetic, improve soil structure, fertility, and overall health, leading to more robust plants and higher agricultural yields. By integrating soil conditioners into farming practices, growers can optimize their soil’s physical, chemical, and biological properties, resulting in healthier crops and sustainable agricultural practices.

What is a Soil Conditioner?

A soil conditioner is a substance added to soil to improve its physical and chemical properties. Unlike fertilizers, which provide essential nutrients to plants, soil conditioners focus on enhancing the soil environment, which helps plants better utilize available nutrients. Common soil conditioners include compost, peat moss, vermiculite, perlite, and gypsum, among others. Each type of soil conditioner serves a specific purpose and offers unique benefits to soil health.

Key Benefits of Soil Conditioners

Improved Soil Structure: Soil conditioners enhance soil texture by improving its aggregation. For example, organic matter such as compost or peat moss helps bind soil particles together, creating a more crumbly and aerated structure. This improved structure facilitates better root penetration, water infiltration, and air circulation, all of which are essential for healthy plant growth.

Enhanced Water Retention: Certain soil conditioners, like organic matter and hydrogels, increase the soil's ability to retain moisture. This is particularly beneficial in sandy soils, which tend to drain quickly and can leave plants stressed during dry periods. By improving water retention, soil conditioners help maintain consistent soil moisture levels, reducing the need for frequent irrigation.

Improved Drainage: In clay soils, where drainage can be a problem, soil conditioners like perlite or coarse sand can help increase soil porosity. This prevents waterlogging and reduces the risk of root diseases caused by excess moisture. Proper drainage ensures that plant roots receive adequate oxygen and minimizes the likelihood of water-related issues.

Increased Nutrient Availability: Soil conditioners enhance the soil’s ability to hold and release nutrients. Organic soil conditioners, such as compost, increase the soil's cation exchange capacity (CEC), allowing it to retain more nutrients and make them available to plants. This reduces the need for additional fertilization and ensures that plants receive a steady supply of essential nutrients.

pH Adjustment: Some soil conditioners can help adjust soil pH, making it more suitable for plant growth. For example, lime is commonly used to raise the pH of acidic soils, while sulfur can lower the pH of alkaline soils. Proper pH levels are crucial for optimal nutrient availability and overall plant health.

Enhanced Microbial Activity: Organic soil conditioners promote the growth of beneficial soil microorganisms. These microbes play a vital role in decomposing organic matter, fixing nitrogen, and enhancing nutrient cycling. A healthy microbial community improves soil fertility and plant health.

Reduction of Soil Erosion: Soil conditioners help stabilize soil, reducing erosion caused by wind and water. By improving soil structure and increasing ground cover, these products help maintain the topsoil, which is essential for sustaining productive agriculture.

Types of Soil Conditioners

Compost: Made from decomposed organic matter, compost enriches soil with nutrients, improves soil structure, and supports beneficial microbial activity. It is one of the most versatile and commonly used soil conditioners.

Peat Moss: This organic material enhances soil moisture retention and improves soil structure. It is particularly useful for improving the conditions of sandy or clay soils.

Vermiculite: A mineral-based soil conditioner that improves aeration and water retention. It is often used in potting mixes and for soil amendment.

Perlite: Another mineral-based conditioner that enhances soil aeration and drainage. It is commonly used in horticultural applications to prevent soil compaction.

Gypsum: Used to improve soil structure in clay soils by reducing compaction and improving drainage. It also helps in alleviating soil salinity.

How to Use Soil Conditioners

Reducing Environmental Impact in Aquaculture through Biofloc Technology

As global demand for seafood continues to rise, the aquaculture industry faces the challenge of increasing production while minimizing its environmental impact. Traditional aquaculture systems often involve excessive water usage, pollution from fish waste, and the discharge of harmful effluents into natural ecosystems. Biofloc Technology (BFT), an innovative approach to sustainable fish farming, has emerged as a solution that addresses these environmental challenges by creating a closed-loop system where waste is treated and recycled. This article explores how Biofloc Technology helps reduce the environmental impact of aquaculture and promotes more sustainable practices.

The Environmental Challenges of Conventional Aquaculture

Conventional aquaculture practices, especially those relying on open water systems, have been associated with several environmental issues:

Water Pollution: Fish farms discharge large volumes of untreated wastewater, containing uneaten feed, fish excreta, and other organic waste. This runoff can lead to the eutrophication of nearby water bodies, causing harmful algal blooms, oxygen depletion, and damage to aquatic ecosystems.

Water Resource Depletion: Traditional aquaculture systems require regular water exchanges to maintain water quality, leading to high water consumption. This is particularly problematic in regions facing water scarcity or in areas where freshwater resources are limited.

Feed Waste: Excessive use of commercial feed, much of which remains uneaten and decomposes in the water, adds to the environmental burden by increasing nutrient loads and contributing to water pollution.

Greenhouse Gas Emissions: Conventional fish farming can contribute to greenhouse gas emissions, particularly methane and nitrous oxide, which are released during the decomposition of organic waste in poorly managed systems.

How Biofloc Technology Reduces Environmental Impact

Biofloc Technology offers an alternative to conventional aquaculture by creating a self-sustaining, closed-loop system where waste is converted into useful resources. This approach minimizes environmental damage while enhancing the efficiency of fish farming.

1. Efficient Waste Management and Water Recycling

One of the core benefits of Biofloc Technology is its ability to treat and recycle waste within the system. In a biofloc setup, microorganisms (mainly bacteria) convert nitrogenous waste, such as ammonia from fish excreta, into microbial biomass. This process helps prevent the accumulation of harmful substances in the water, maintaining water quality without the need for constant water exchanges.

The ability to recycle water and reduce wastewater discharge significantly decreases the environmental footprint of aquaculture operations. By lowering the amount of polluted water released into natural ecosystems, Biofloc Technology helps prevent eutrophication and other forms of aquatic pollution, preserving biodiversity and maintaining the health of surrounding water bodies.

2. Reduced Water Usage

Traditional aquaculture systems are water-intensive, often requiring daily water changes to manage water quality. In contrast, biofloc systems recycle water within the farm, reducing the need for frequent water exchanges. Water is conserved, making Biofloc Technology an ideal solution for regions facing water scarcity or for farms seeking to minimize their water consumption.

This reduction in water usage not only lowers the environmental impact of fish farming but also makes aquaculture more accessible in areas where freshwater resources are limited.

3. Lower Dependence on Commercial Feed

In biofloc systems, microorganisms not only purify the water but also form biofloc particles—aggregates of organic matter, bacteria, and nutrients. These bioflocs are rich in protein and can be consumed by fish as a natural feed source, reducing the need for expensive commercial feeds.

By recycling nutrients in the form of bioflocs, Biofloc Technology cuts down on the amount of external feed required. This reduces the environmental impact associated with feed production, including deforestation (for soy-based feeds), overfishing (for fishmeal and fish oil), and the energy-intensive processes involved in manufacturing commercial feeds.

4. Enhanced Fish Health and Reduced Use of Chemicals

Maintaining stable water quality through natural microbial processes helps reduce the incidence of diseases in fish. In conventional aquaculture systems, poor water quality can lead to stress and disease outbreaks, often necessitating the use of antibiotics, pesticides, and other chemicals. These substances can leach into surrounding water bodies, harming non-target organisms and disrupting ecosystems.

By improving water quality and supporting healthier fish, Biofloc Technology reduces the need for chemical interventions, lowering the risk of environmental contamination and promoting more eco-friendly aquaculture practices.

5. Reduced Greenhouse Gas Emissions

In conventional aquaculture systems, the decomposition of uneaten feed and fish waste can produce greenhouse gases, including methane and nitrous oxide. These gases contribute to climate change and are more potent than carbon dioxide. Biofloc Technology mitigates this issue by transforming waste into useful microbial biomass, reducing the likelihood of anaerobic decomposition and the production of harmful gases.

By reducing greenhouse gas emissions and minimizing the release of pollutants, biofloc systems contribute to climate change mitigation and make aquaculture more sustainable.

Additional Benefits of Biofloc Technology for Sustainability

Beyond reducing environmental impact, Biofloc Technology offers several other benefits that promote sustainable fish farming:

High Stocking Density: Biofloc systems allow for higher stocking densities without compromising water quality, leading to more efficient use of space and higher yields. This helps reduce the need for extensive land areas, minimizing habitat destruction associated with traditional fish farms.

Energy Efficiency: While biofloc systems require continuous aeration to support microbial activity, advances in aeration technology and system design have made these systems more energy-efficient. This helps balance the energy input required for sustainable aquaculture practices.

Local and Small-Scale Farming Potential: Biofloc systems can be implemented on a small scale, making them suitable for local farmers and communities. This decentralization of fish farming helps reduce transportation costs and the carbon footprint associated with the distribution of seafood.

Conclusion

Biofloc Technology represents a significant step forward in reducing the environmental impact of aquaculture. By efficiently managing waste, conserving water, and lowering dependency on external resources, biofloc systems offer a sustainable alternative to conventional fish farming methods. As the world faces increasing pressure to produce food in an environmentally responsible manner, Biofloc Technology provides a promising solution for the future of aquaculture—one that balances productivity with the protection of our planet's ecosystems.
