Does Sodium Alginate produce a different texture slime or something? I looked it up online and while it is used for thick water, a lot of pharmacies will sell thick water that uses cornstarch or xanthan gum as a thickener. And its use in dyemaking is mostly because it won't chemically bond to the coloring agents.

Is there any reason to make slime out of sodium alginate-thickened water instead of just school glue or cornstarch? Or is this just online trends being stupid as online trends often are?

apparently people are now purchasing thick water to make slimes with because of a trend on tiktok

thick water is for disabled people who can’t swallow properly. stores usually have extremely limited supplies of it.

please don’t buy thick water for fun or to make slime with. it’s literally the only way some disabled people can drink anything. It’s not a fucking toy

Sodium alginate is a commonly used thickener and gelling agent with a wide range of applications in food and other fields. This article will introduce the characteristics and main uses of sodium alginate.

Sodium alginate is a natural polysaccharide extracted from seaweed. Its chemical structure is a linear polysaccharide containing alginic acid units and sodium ions. Sodium alginate has many unique characteristics that make it a popular thickener and gelling agent.

First, sodium alginate has excellent thickening capabilities. When it is dissolved in water, it can form a viscous colloidal solution due to the special structure of its molecular chain. This solution has high viscosity and viscosity, so it is suitable for various foods and beverages, such as jams, jelly, salad dressings, milkshakes, etc., and can give the products good texture and taste.

Secondly, sodium alginate has good stability. It can combine with calcium ions in water to form a gel state, thereby increasing the stability and ductility of the product. This is particularly important in dairy and frozen products, preventing the product from separating or crystallizing, increasing its shelf life and improving taste.

In addition, sodium alginate also has excellent gelling ability. When sodium alginate is combined with calcium salts or other multivalent cations, a strong gel is formed. This gel can be used to make frozen foods such as jelly, pudding, etc. The formation of gel also helps retain moisture and nutrients in food, improving food quality.

In addition to the food field, sodium alginate is also used in many other fields. In the pharmaceutical field, sodium alginate is often used to prepare capsules, tablets and suppositories for controlled release and stabilization of drugs. In the field of cosmetics, it is often used to thicken lotions, gels and facial masks to improve the texture and use experience of the product. In addition, sodium alginate is also used in the textile, paper and printing and dyeing industries as a binder and thickener.

All in all, sodium alginate is a versatile thickener and gelling agent that plays an important role in food and other fields. Its characteristics include good thickening ability, stability and gelling ability, which can give the product good texture, mouthfeel and stability. Whether in food, medicine, cosmetics or industry, sodium alginate is a high-quality additive worth using.

Study on the storage stability of phycocyanin from Spirulina obtusususiae

Abstract: The effects of temperature, sunlight and different additives on the stability of aqueous solutions of phycocyanin were studied. It was concluded that phycocyanin should be stored at 40 ℃ and protected from light, and should be stored under neutral conditions; glucose, sodium chloride and sorbitol could effectively improve the stability of phycocyanin, and the pigment preservation rate of phycocyanin increased from 50.90% to 78.10%, 67.02% and 69.08% after 72 h at room temperature, respectively; the stabilizers of phycocyanin were compounded with glucose, sodium chloride and sorbitol in the mass ratio of 1 : 1 : 0.3 and left at 4 ℃ for 14 days. After adding glucose, sodium chloride and sorbitol as stabilizers in the mass ratio of 1:1:0.3, the pigment retention rate of the alginate was increased by 54.4% compared with that of the unadded alginate after being placed at 4 ℃ for 14 d. The pigment retention rate of the alginate added with the additive was increased by 16.1% compared with that of the unadded one after being placed at 25 ℃.

Spirulina (English name spirulina), also known as "spirulina", belongs to the family of Cyanobacteria, Chlamydomonas; at present, there are three types of large-scale cultivation at home and abroad, namely, Spirulina major, Spirulina obtususus and Spirulina indica. Spirulina obtususus is a blue-green seaweed (cyanobacteria) belonging to the Candida family.

It is a non-branched, multicellular spiral mycelium with a length of about 200 μm~300 μm and a width of about 5 μm~10 μm [1]. The amino acid composition of the proteins contained in Spirulina obtusususiformis is very uniform and reasonable, which suggests that it can be used as a potential health food for human beings [2].

Phycocyanin is one of the photosynthesizing proteins in the phycobilins, which are chromophore polypeptides consisting of α and β subunits with a molecular weight of about 20,000 daltons [3]. The phycobilisome in the cyanobacterium Spirulina obtususus is composed of an alpha and beta subunit in the center and a phycocyanin in the periphery. Phycocyanin is the most important bile protein in Spirulina, accounting for about 20 % of the dry weight [4-6]. It has a blue color in aqueous solution and fluoresces in purple. The UV-Vis spectra of phycocyanin in Spirulina obtusususiformis show characteristic absorption peaks at 278, 360 and 620 nm [7]. It has also been shown that the maximum absorption peak of L. obtususus is at 620 nm and its fluorescence emission peak at room temperature is at 645 nm [8].

Natural pigments are very rich in variety and are classified according to a variety of bases. According to solubility can be divided into fat-soluble pigments, water-soluble pigments; according to the source can be divided into animal pigments, microbial pigments and phytochromes; in order to classify the different chemical structures for anthocyanins, carotenoids and other five categories [9-10].

Alginin is a natural blue pigment with high application value. It has been shown to be anticancer[11-12] and can be used as a health food for patients with enteritis[13] . It is highly water-soluble and can be easily extracted from Spirulina. In the process of extraction and purification, the control of pH value and ionic strength is very crucial for the stability of algal blue protein. The discoloration and denaturation of phycocyanin is determined by the grade of protein polymers, and its polymer form is mainly affected by light intensity, light time, temperature, pH value, irradiation and protein concentration [14-17].

It has been studied that the higher concentration of sodium chloride can protect the stability of alginate, and the appropriate amount of sodium benzoate can protect the color and preservation of alginate to a certain extent [18-19], but the stability of alginate is still low. Therefore, on the basis of previous studies, this experiment was carried out to investigate the effects of different food-grade additives as well as glucose, sodium chloride and sorbitol additives on the stability of alginate.

1 Materials and Methods

1.1 Materials and Main Instruments

Appropriate amount of spirulina powder was dissolved in distilled water according to the material-liquid ratio of 1:40 (mass ratio), and then stirred with a stirring rotor at a speed of 1,000 r/min for 1.5 h. It was frozen at -18 ℃, and then thawed rapidly in a 37 ℃ water bath for 24 h. After repeating this procedure for four times, it was centrifuged at a high speed for 10 min at 10,000 r/min, and the absorbance at 620 and 280 nm was measured after taking the supernatant and diluting it with appropriate multiplicity.

1.3 Research on storage stability of algal blue protein

1.3.1 Effect of temperature on the stability of phycocyanin[19]

30 mg of alginate was dissolved in 30 mL of citrate phosphate buffer at pH 5.0, 6.0 and 7.0, and incubated in 6 temperature gradients (20, 30, 40, 50, 60 and 70 ℃) for 30 min. The absorbance was measured at 620 nm after appropriate dilution, and the pigment retention rate was calculated. The pigment retention rate was calculated according to equation (1):

Pigment retention rate/% = ×100 Equation (1)

1.3.2 Effect of daylight illumination on the stability of phycocyanin [19]

Two groups of 1 mg/mL aqueous phycocyanin solution were taken, one group was irradiated under a single light source (sunlight) and the other group was stored away from light, and then diluted appropriately after 12, 24, 36, 48, 60, and 72 hours, respectively, and the absorbance value was measured at 620 nm to compare the changes in the retention rate of phycocyanin pigments.

1.3.3 Effect of pH on the stability of algal blue protein

Take 0.1 g of alginate powder and dissolve it in 100 mL of citrate phosphate buffer with pH value of 5.0, 5.5, 6.0, 6.5 and 7.0 respectively, there are 5 groups in total, and take samples at 30 min intervals to dilute appropriately, and measure the absorbance value at the wavelength of 620 nm, and then compare the changes of the preservation rate of the alginate pigment.

1.3.4 Effect of food additives on the stability of algal cyanoproteins [20-21]

Take 100 mL of algal blue protein solution with a concentration of 1 mg/mL, and add the following additives in order according to the maximum additive amount of food additives stipulated in GB 2760-2011 Standard for the Use of Food Additives: glucose (5 g), sucrose (5 g), sodium chloride (5 g), sorbitol (0.003 g), sodium benzoate (0.000 2 g), ascorbic acid (0.002 g), and sodium benzoate (0.000 2 g), and the following additives are added to the solution. 0.002 g). After 24, 48 and 72 hours of exposure to sunlight at room temperature and appropriate dilution, the absorbance value at 620 nm was measured to compare the changes in the retention rate of phycocyanin pigments. The effects of different concentrations of glucose and sodium chloride on the stability of algal blue protein were measured according to the above method. Select appropriate concentrations of glucose, sodium chloride and sorbitol and add them into the aqueous solution of phaeocyanin, and carry out the test according to the above method to observe the change of pigment retention rate.

2 Results and analysis

2.1 Effect of temperature on the stability of phycocyanin

The effect of temperature on the stability of phycocyanin is shown in Fig. 1.

As can be seen from Fig. 1, the pigment retention rate of algal blue protein decreased with the increase of temperature when it was placed at different temperatures for 30 min. When the temperature was 20 ℃

The pigment retention rate of alginate stored at 40 ℃ was almost unchanged; the pigment retention rate of alginate stored at 50 ℃ and 60 ℃ decreased by 11.68% and 20.71%, respectively, compared with that of the initial one after 30 min, and the pigment retention rate of alginate stored at 70 ℃ showed the greatest decrease, which was 58.58% lower than that of the initial one.

High temperature will destroy the structure of algal blue protein and cause its denaturation, resulting in a decrease in the pigment retention rate of algal blue protein. It can be seen from the results that phycocyanin has the highest and most stable pigment retention rate between 20 ℃ and 40 ℃. Therefore, high temperature storage should be avoided below 40 ℃.

2.2 The effect of light on the stability of phycocyanin

The effect of sunlight illumination on the stability of phycocyanin is shown in Fig. 2.

As can be seen from Fig. 2, under the irradiation of room temperature and single sunlight source, the pigment retention rate of the algal blue protein solution decreased greatly from 48 h. At the same time, the color fading was obvious, and the color gradually changed from sapphire blue to light blue from 48 h, and became almost colorless and transparent at 60 h. The pigment retention rate decreased by 59.31% compared with that at 0 h, and the rate of the pigment retention rate was only 29.26% of the initial one at 72 h. The color retention rate of the solution decreased from 0 h to 60 h, and the color retention rate of the solution was only 29.26% of the original one at 72 h. After 72 h, the pigment retention rate was only 29.26%. The pigment retention rate of phycocyanin stored at room temperature under the condition of light protection was higher than that of sunlight, but the effect was not great, and the pigment retention rate of phycocyanin at 72 h was 13.51% higher than that of sunlight. It can be concluded that the sensitivity of phycocyanin to heat is greater than that to light, but light also has a certain effect on the pigment stability of phycocyanin. Therefore, phycocyanin should be stored under light-proof conditions.

2.3 Effect of pH value on the stability of algal blue protein

The effect of pH on the stability of phycocyanin is shown in Fig. 3.

Figure 3 shows that the pigment retention rate of phycocyanin solution at pH 5.0, 5.5, 6.0, 6.5 was small, and the pigment retention rate was kept in the range of 95.49%~102.19%; and it can be seen that the phycocyanin was the most stable and the highest pigment retention rate was found at pH 6.0. At pH 7.0, the pigment retention rate decreased greatly, from 100 % to 87.46 % gradually. This may be due to the fact that the alkaline condition damaged the structure of phycocyanin, so it should be preserved in neutral condition instead of alkaline condition.

2.4 Effect of additives on the stability of algal blue proteins

The effect of food additives on the stability of algal blue proteins is shown in Fig. 4.

Additive type

Fig. 4 Effect of food additives on the stability of algal blue proteins

Fig.4 The influence of food additives on stability of phycocyanin

Figure 4 shows that the retention rate of phycocyanin pigments in phycocyanin solutions with different additives increased and then decreased during 72 h of storage at room temperature under sunlight. This may be due to the incomplete dissolution of phycocyanin at the beginning. The highest pigment retention was observed in the alginate with glucose, sorbitol and ascorbic acid, which decreased from the initial 100 % to 78.10 %, 69.08 % and 67.24 %, respectively, which was significantly higher than that of the blank group (50.90 %). This may be attributed to the fact that the additives can protect the color of the algal blue protein and increase its pigment retention rate. However, the solution of phycocyanin with ascorbic acid produced a large amount of precipitation. Therefore, glucose, sodium chloride and sorbitol were selected for further study.

2.5 Effect of glucose concentration on the stability of algal blue proteins

The effect of glucose concentration on the stability of phycocyanin is shown in Fig. 5.

As shown in Fig. 5, the color retention rate of glucose-added phaeocyanin increased after 24 h, and then decreased with time. This may be due to the color protection effect of glucose on phycocyanin. The pigment retention rate of the alginate without glucose did not change much after 24 h at room temperature. When the concentration of glucose was 10 mg/mL, the absorbance value of phycocyanin increased greatly after 24 h, and the pigment retention rate of phycocyanin increased by 16.15%, which was 12.62% higher than that of phycocyanin without added glucose; the pigment retention rate of phycocyanin with added glucose at 10 mg/mL reached 78.09%, which was 27.19% higher than that of phycocyanin without glucose. After 72 h, the color retention rate of the solution with 10 mg/mL glucose reached 78.09%, which was 27.19% higher than that of the solution without glucose, and then the retention rate of alginate color tended to slow down as the concentration of glucose solution increased. Therefore, for the purpose of cost saving, 10 mg/mL of glucose was chosen for the next study.

2.6 Effect of sodium chloride concentration on the stability of algal blue proteins

The effect of NaCl concentration on the stability of algal blue protein is shown in Fig. 6.

Fig. 6 Effect of sodium chloride concentration on the stability of algal blue protein

As can be seen from Fig. 6, the pigment retention rate of the alginate without NaCl remained almost unchanged after 24 h, while the absorbance values of the alginate with NaCl increased, which was attributed to the protective effect of NaCl on the color of the alginate to inhibit the denaturation of the alginate. The color retention rate of the solution with 10 mg/mL NaCl was significantly higher than that of the blank group after 72 h, reaching 75.90%, and then leveled off. Therefore, in order to save the cost of the experiment, 10 mg/mL NaCl was chosen for the next study.

2.7 Effects of sorbitol, sodium chloride and glucose on the stability of phycocyanin

The effects of sorbitol, NaCl and glucose on the stability of phycocyanin are shown in Figure 7.

Figure 7 shows the complex color protection effect of the three additives on phycocyanin. The pigment retention rate of the alginate solutions increased to different degrees after 24 h at room temperature under sunlight, which was attributed to the color protection effect of the additives. In the blank group, the pigment content of the alginate solution remained almost unchanged after 24 h, and then decreased rapidly; the absorbance value of the alginate solution with the addition of sorbitol, dextrose and sodium chloride increased the most obviously, which was 41.29% higher than that at 0 h, and 38.38% higher than that of the alginate solution without the addition of the additives; and the color preservation was 23.01% higher than that of the blank group at 72 h. The effect of color preservation was very obvious. After 72 h, the color preservation rate was higher than that of the blank control group by 23.01%, and the color preservation effect was obvious. The stability of sorbitol-added phycocyanin was second, and its pigment preservation rate was 19.09% higher than that of the blank control group after 72 h at room temperature under sunlight. This is due to the compound effect of sorbitol, glucose and sodium chloride on alginate to play a good role in color protection and preservation, which is better than several other combinations of additives. Therefore, sorbitol, dextrose and sodium chloride can be added as compound stabilizers in alginate at a mass ratio of 1 : 1 : 0.3.

2.8 Effect of three additives on the stability of algal blue proteins

The initial pictures of phycocyanin (without additive) and phycocyanin (with additive) at (4±5)°C and (25±5)°C are shown in Fig. 8, and the pictures of phycocyanin (without additive) and phycocyanin (with additive) at (4±5)°C and (25±5)°C after 14 d are shown in Fig. 9, and the effects of three additives on the stability of phycocyanin are shown in Fig. 10.

Figures 8, 9 and 10 show the changes in pigment content of phycocyanin after the addition of glucose, sodium chloride and sorbitol as stabilizers for 14 d. The pigment retention rate of phycocyanin solutions decreased with the increase of storage days and varied under different conditions. The pigment retention of phycocyanin solutions decreased with the increase of storage days, and the pigment retention varied under different storage conditions. The most suitable storage condition for phycocyanin solution was 4 ℃ with preservative, and its pigment retention rate only decreased by 30.21% after 14 d of storage, which was 54.5% higher than that of phycocyanin stored at 4 ℃ without additive. However, the pigment retention rate of the unadditive alginate solution was almost zero after 14 d of storage at 25 ℃, with almost total loss of phycocyanin, and the pigment retention rate of the additive solution was 16.1% higher than that of the unadditive one. The pigment retention rate of the additive solution was significantly higher than that of the unadditive one at 25 ℃ and 4 ℃, which was attributed to the excellent color protection and anticorrosive effect of the three additives on the phycocyanin. This is due to the fact that the combination of the three additives has a good effect on the color protection and preservation of phycocyanin. Therefore, alginate is suitable for storage at low temperature with additives.

3 Conclusion

Differences in temperature, sunlight and pH all affect the storage stability of phycocyanin, with temperature having the most pronounced effect on the stability of phycocyanin and sunlight having a lesser effect on the stability of phycocyanin.

Appropriate concentrations of sorbitol, dextrose and sodium chloride can obviously protect the color of alginate and preserve it, and do not affect its properties. In this experiment, the three additives were added into the aqueous solution of phycocyanin, and it was found that they had obvious improvement effects on the storage stability of phycocyanin pigments. The compound additives added to phycocyanin can be widely used in food, cosmetics and other fields, and has high application value.

An edible CBD coating could extend the shelf life of strawberries

Soon, you'll be able to get a box of freshly picked, sweet strawberries from the grocery store or local farm stand. But it's disappointing when you get them home and find that the ones at the bottom have started to rot. To increase the berries' shelf life, researchers reporting in ACS Applied Materials & Interfaces have incorporated cannabidiol—a non-hallucinogenic compound from cannabis known as CBD—and sodium alginate into an edible antimicrobial coating.

CBD is popular because of its potential therapeutic effects. But this cannabinoid has also been shown to have antioxidant and antimicrobial properties. In previous studies, CBD limited the growth of some bacteria and pathogenic fungi, such as the ones that cause fresh fruits and vegetables to rot.

However, the oily compound needs to be evenly distributed in water before it can be widely incorporated into foods or used for food preservation. One possible way to do this is to encapsulate the CBD molecules in edible polymers. So, Pongpat Sukhavattanakul, Sarute Ummartyotin and colleagues wanted to see if a food coating made using CBD-filled nanoparticles could promote antimicrobial activity and extend the freshness of strawberries.

Medicine Seller (Mononoke) Progress - Kimono + Obi: How I Made It

👾 SLEEVES 👾 These are entirely made of damaged or used kimono — and every piece is also dyed to be a similar shade/tone, so the whole thing has deep colors and is cohesive! I got my kimono from Tangerine Mountain kimono and Yoko Beverly Hills primarily; anything not cut or unused was donated to others. All patches are fused with mistyfuse, then sashiko’d on by hand. Fun fact: all the sashiko patterns are tied with the earth or spirits, with the Seven Treasures of Buddhism for the purple, waves of grass for the green, and ocean waves for the blue! 👾 KIMONO FLOWERS 👾 The white flowers were stenciled with Jacquard textile paint in white, before I mixed sodium alginate (a dye thickener) with Dharma Trading Co ’s Teal Blue fiber reactive dye and blended the outlines, making it look a bit more “worn”. 👾 OBI 👾 This was, by and far, the most challenging thing I’ve ever done. I decided to batik (or wax resist) the obi. I started with white raw silk, dyed Golden Yellow with fiber reactive — vinegar has to be added for it to stick better to silks. I then applied the Jacquard wax by brush (all 4 yards of fabric, bless Dharma Trading Co for their amazing brushes), and then — to prevent the yellow from going orange — did another HEAVY wine colored dye bath (Burgundy dye with a touch of Deep Space), LOTS of salt and vinegar to overwhelm the yellow, and it WORKED! I did over 15 different dye tests for this and it WORKED! 👾 KIMONO 👾 This started as the rayon/linen blend fabric from Dharma Trading Co in white. The whole thing was dyed with their fiber reactive dye in Teal Blue, then, I did arashi shibori, or pole-wrapping shibori, with the dye in Navy and Deep Space.

Sodium Alginate: A Versatile Ingredient for Culinary and Industrial Applications

Sodium alginate is a natural polysaccharide derived from brown seaweed. It has gained significant popularity in recent years due to its diverse applications in various industries, ranging from food and pharmaceuticals to textiles and cosmetics. This blog will delve into the properties, uses, and availability of sodium alginate, including its price and where to buy it.

Properties of Sodium Alginate

Sodium alginate is a white or pale yellow powder that is soluble in water and forms a viscous gel when exposed to divalent cations, such as calcium. Its unique chemical structure enables it to act as an excellent gelling, thickening, and stabilizing agent in various formulations. It is known for its high viscosity and film-forming properties, making it a versatile ingredient in numerous applications.

Food Industry Applications

In the food industry, sodium alginate is widely used for its gelling and thickening properties. It is commonly employed in the production of jelly, pudding, and other gel-based desserts. The ability of sodium alginate to create a gel-like texture when combined with calcium ions makes it ideal for encapsulating flavors and creating unique culinary experiences. Additionally, it is used in the formulation of salad dressings, sauces, and beverages to enhance texture and improve stability.

Industrial Applications

Beyond the culinary world, sodium alginate finds extensive use in various industrial applications. In the textile industry, it is utilized as a sizing agent, imparting strength and flexibility to fabrics. Sodium alginate acts as a binder, preventing the fabric from losing its shape during manufacturing processes. It is also employed in the printing industry as a thickener for textile dyes, ensuring precise and even distribution on the fabric.

Sodium alginate has found a place in the pharmaceutical and cosmetic industries as well. It is used as an excipient in pharmaceutical formulations, providing stability and controlling the release of active ingredients. In cosmetics, it is added to skincare products, such as face masks and lotions, for its moisturizing and film-forming properties. Sodium alginate helps create a protective barrier on the skin, locking in moisture and leaving it soft and supple.

Price and Where to Buy

The price of sodium alginate can vary depending on the supplier, quantity, and quality of the product. Generally, sodium alginate is priced per kilogram (kg) and is available in different grades, such as food-grade and pharmaceutical-grade. It is recommended to purchase from reputable suppliers to ensure quality and authenticity.

Sodium alginate can be obtained from various sources, including local chemical suppliers, specialized food ingredient stores, and online marketplaces. Conducting a quick search using keywords like "sodium alginate where to buy" or "sodium alginate near me" can provide you with a list of nearby stores or online platforms that offer this versatile ingredient.
