With the properties of chelating metal ions, increasing protein water holding capacity, PH buffering, stabilization, emulsification, casein thickening and ect, tetrasodium pyrophosphate is widely used in food to improve the gel strength and the tenderness of meat products/analogs.

Also, it is used with other phosphates (e.g. sodium hexametaphosphate, sodium acid pyrophosphate) in seafood to increase the water retention.

Food
Food grade TSPP is mainly used in following two functions:

A buffering agent: with the PH value from 9.8 to 10.8 (1% solution), TSPP can be used as an alkaline to adjust pH in processed food, pudding and etc.
A calcium sequestrant: TSPP can remove naturally occurring calcium ions from proteins and crosslink with proteins, which results in accelerating protein gelation, improving texture (mouthfeel) and reducing cooking loss in meat analog production (e.g. soy protein).
Following food list may contain TSPP:

Meat analogs, such as soy or wheat based food, with the appearance, flavor and mouth-feel the same with meat but not made from meat.
Marshmallows
Pudding
Cheese
Ice cream
Milk protein products
Tuna
Toothpaste
Orally the main purpose of TSPP is to prevent the formation of calculus by reducing the deposition of calcium and magnesium on teeth. Thus it is commonly used as the anticalculus component of many tartar-control toothpastes and mouth rinse. Disodium pyrophosphate also has the same function.

The top toothpaste manufacturer, Crest also uses it as the anti-tartar ingredient in its whitening expressions.

Nowadays, Sodium Alginate is also used in the biological experiments for the immobilization of cells to obtain important products like alcohols, organic acids, etc.Sodium alginate is combined with calcium lactate or similar compound to create spheres of liquid surrounded by a thin jelly membrane as thickeners.Sodium Alginate is a natural amylose carbohydrate distilled from alga.As the natural cellulose, It slow the absorption of fatty sugar .and bilesalt , reduce serum cholesterol , triglyceride in the blood.

Sodium Alginate Application in the food:
Food grade sodium alginate in lieu of starch, gelatin stabilizers for ice cream, can control the formation of ice crystals to improve the taste of ice cream, but also the stability of the sugar ice cream, ice sherbet, frozen mixed drinks such as milk. Many dairy products, such as refined cheese, whipped cream, dry cheese such as the stabilizing effect of the use of sodium alginate to prevent food and packaging with adhesive, can be used as a dairy jewelry covering it to remain stable and to prevent icing cakes skin cracking. Sodium alginate for the salad (a salad) sauce, pudding (a dessert), jam, ketchup, and canned products, thickener, in order to improve the stability properties of the products, and reduce fluid leakage. Sodium alginate can improve the adhesion of the products the organization added to the noodles, vermicelli, rice production, so that tensile strength, bending degree, reduce breakage rates, especially for low-gluten flour, the effect is more obvious. Adding sodium alginate, bread, cakes and other products to improve the homogeneity of the products of the internal organization of the water retention effect, extend the storage time. Add the frozen confectionery products can provide the heat fusion layer of protection to improve the flavor oven to improve the performance of the melting point. Sodium alginate can be made into a variety of gel food, maintain the colloidal form, does not occur exudate or contraction, suitable for frozen food and Man-made food. Can also be used to cover the fruit, meat, poultry and aquatic products as a protective layer, not in direct contact with air to extend the storage time. Also as bread, sugar, pie filling, snacks coated cap rock, canned food, self-curing agent. The artificial egg can still be in the high temperature, freezing and acidic media dimension by adding sodium alginate to hold their original shape. Also instead of agar made from flexible, non-stick teeth, transparent crystal candy.



In pharmaceutical preparations

Sodium alginate as early as 1938 had income of the United States Pharmacopoeia. The alginate income in 1963 British Pharmacopoeia. Alginic acid is insoluble in water, but into the water to swell. Therefore, traditionally, sodium alginate as a tablet binder, while the alginate is used as a rapid release tablets disintegrant. However, sodium alginate tablets nature depends on the amount placed in the prescription, and in some cases, sodium alginate may promote the collapse of the tablet. Sodium alginate can join in the granulation process, rather than in the form of a powder after granulation to join, so that the production process easier. Compared to the use of starch, the greater mechanical strength of the system into a film. Sodium alginate suspensions, gels, and the production of concentrated emulsion matrix of fats and oils. Sodium alginate for some liquid drugs can enhance the viscosity, improve solids suspension. Propylene glycol alginate can improve the stability of the emulsion. Controlled release drug delivery system in the health care account for a very important position. Water-soluble drug particles separated from the colloidal media before the time to be minimized to ensure maximum drug loading. However, this water-insoluble drugs are not important. They found that the drug release and solubility of the drugs used. One researcher reported that the swelling of the alginate gel particles with pH sensitivity, such as particles in distilled water or acidic media (pH1.5KCl-HCl) did not change, the rapid swelling in pH7.0 phosphate buffer, size larger. Sodium alginate on the acid-sensitive This feature is useful to drugs allows drug against acid attack, and in the small intestine dry Swelling allows drugs to the desired rate of release. Another researcher through the controlled release preparation containing diclofenac sodium solution will be sodium alginate cross-linked with glutaraldehyde into ethanol under acidic conditions (slightly soluble in water) sodium alginate small ball. Embedding rate of 30% to 71%, and its value depends on the preparation conditions. Temperature during preparation of the ball or to extend the exposure time of the cross-linked material, make the embedding rate, the drug release time.



Application in the pharmaceutical industry

Dispersant made of PS type stomach intestine double contrast barium sulfate preparations, alginate sulfate has a low viscosity, fine particle size, the mural is a good, stable performance. PSS is a Fucoidan diester sodium alginate as raw material, has anti-clotting, lowering blood pressure and reduce blood clotting. Sodium alginate instead of rubber, plaster for dental impression material, not only cheap, easy to operate, and printed more accurate tooth. Sodium alginate can produce various formulations of the hemostatic agent, including hemostatic sponge, hemostatic gauze, hemostatic film, scald gauze, spraying hemostatic agent.



Sodium alginate in the textile industry

Help agent, sodium alginate for reactive dyes used in printing and dyeing industry as a paste of reactive dyes, better than the food starch and other pulp. Printed textile pattern bright, clear lines, high color yield and dye evenly, good penetrability and plasticity. Sodium alginate is the best plasm for modern printing and dyeing industry has been widely used in the printing of cotton, wool, silk, nylon and other fabrics, it is applicable for discharge printing paste. Warp yarn stiffening material Textile department of our sodium alginate starch mixed or instead of starch to confect warp, not only can save lots of food, but also make fiber of warp lint, abrasion breakage rate, thereby improving the efficiency of weaving. Sodium alginate cotton fibers and synthetic fibers.

Sodium Alginate is the sodium salt and is alginic acid. It is a gum, extracted from the cell walls of brown algae.In recent years, It has been used in molecular gastronomy at some of the best restaurants in the world.

Food grade sodium alginate is widely used in food, especially in dairy-based frozen products (e.g.ice creams, yogurts, puddings, cheese sauce and desserts) because of its properties of thickening, gelling, and stabilizing.

It can be used for the following applications:

Ice cream
It provides a smooth and soft mouthfeel, and also stabilizes the bubbles in frozen ice cream and prevents the formation of sugar crystals.

Spherification
Sodium alginate and calcium chloride or calcium lactate can be used together to shape a liquid into squishy beads or worms as calcium ions can make sodium alginate to gel. This way can encapsulate food color and flavor into the spheres.

Meat
Sodium alginate (with calcium chloride) can be used as a texturizer in meat to retain the water, enhance the elasticity and adhesion of meat products, and improve the freshness of finished products.

The principle is that sodium alginate and calcium ions form a gel of calcium alginate that holds the water in the meat.

Supplements
It can be used in dietary supplements to adjust appetite and energy intake. Alginate–konjac–xanthan polysaccharide complex (PGX) is made by blending sodium alginate, konjac glucomannan and xanthan gum in a specific ratio which is used in fortified foods and supplements.

Feed
It can also be used as a binder in pets products, other non-food-producing animals and fish.

Pharmaceuticals
It can be used as an active ingredient to reduce reflux of gastric content or an excipient in pharmaceutical products.

Sodium Acetate Anhydrous in food

Sodium Acetate Anhydrous can be added to food seasonings. Sodium Acetate Anhydrous strains can be used in the form of sodium - a 1:1 complex of sodium acetate, acetic acid, Sodium Acetate Anhydrous up. Frequent use of this form of salt and vinegar chips in the United States. Many U.S. brands, including domestic production and sales "segments lying salt and vinegar" chips, use a small percentage of the lactose Sodium Acetate Anhydrous and other chemicals to salt and vinegar instead of real preparation.

Sodium Acetate Anhydrous in industry:
Sodium Acetate Anhydrous for the textile industry, waste and sulfuric acid, aniline dyes. When using Sodium Acetate Anhydrous photoresist it is also a chrome tanning agent impregnated, and Sodium Acetate Anhydrous help slow the production of chloroprene synthetic rubber vulcanization.

Sodium acetate is a multifunctional ingredient that can be used in food, medicine, DNA isolation, printing and dyeing, photography, electroplating, tanning, rubber, and etc.

Let’s see some of its applications:

Food
This ingredient can be found in salad dressing, sauce, dumpling, sausage, steamed fish paste, bread and rice cake.

There are general three purposes of sodium acetate in food:

PH regulator or a buffer: maintain a specific pH content in food when used together with acetic acid and sometimes in the form of sodium diacetate, which is a molar ratio of 1:1 sodium acetate and acetic acid.
Preservative: prevent microorganism cultivation.
Taste improver: the combination of acetic acid to make the sour (vinegar) taste of acetic acid mild.
Medical use
It can be used as an electrolyte replenisher to prevent low levels of sodium in blood.

Meanwhile, sodium acetate trihydrate can be used in reusable heating pads and hand warmers as it contains three waters of crystallization, which will be released from the crystal if heated to its melting temperature – 58°C.

And then sodium acetate dissolves in three waters of crystallization and forms a supersaturated solution. Such solution (not stable) will not form crystals when cooled to room temperature, but can be crystallized again if with some method.

The process of crystallization is exothermic (emit heat) and this property can be utilized in hot packs and hand warmers.

DNA extraction/precipitation
Sodium acetate and ethanol are commonly added to extract nucleic acids (DNA or RNA) from aqueous solution.

Nucleic acids are polar and soluble in water. Sodium acetate is used to make the nucleic acids molecule insoluble in water by neutralizing the negative charges (PO3- groups) on the sugar phosphate backbone of nucleic acids with the dissociated sodium ions.

Compared with water, ethanol enables the interaction between Na+ and PO3- much easier, making nucleic acids precipitate out of solution.
