Sodium Phytate with CAS 14306-25-3

1. Food industry: Multi-functional food additives
Sodium phytate is commonly used as an antioxidant, color protector and quality improver. Its specific functions are as follows:
Color protection and preservation: Chelate Fe³⁺ and Cu²⁺ in food (these ions can catalyze the oxidation of oils and the degradation of pigments), delay the Browning of meat (such as beef and pork), fruits (such as apples and pears), and vegetables (such as potatoes), and extend the shelf life;
Antioxidant: Phytic acid sodium salt in edible oils and fried foods inhibits the oxidation and rancidity of oils (to avoid the production of rancid taste), and replaces some synthetic antioxidants (such as BHA, BHT);
Quality improvement: Phytic acid sodium salt in meat products (such as sausages and hams) improves the water-holding capacity and tenderness of the meat. In baked goods (such as bread and biscuits), it delays the aging of starch (maintaining a soft texture);
Metal ion removal: Sodium phytate chelates excessive metal ions in beverages (such as fruit juice and beer) to prevent the formation of precipitates (such as calcium oxalate precipitate in beer), ensuring the clarity of the beverage.
2. Pharmaceuticals and health supplements: Auxiliary functional ingredients
Lowering blood lipids and preventing kidney stones: In health supplements, Sodium phytate can chelate Ca²⁺ and Mg²⁺ in the intestinal tract, reducing the absorption of cholesterol (lowering blood lipids), while inhibiting the formation and growth of calcium oxalate stones (the main component of kidney stones).
Metal poisoning detoxifier: Sodium phytate, as an auxiliary detoxifier, is used in the treatment of heavy metal poisoning (such as lead, mercury, and cadmium). It forms non-toxic chelates through heavy metal ions within the chelate and is excreted through urine.
Oral care: Phytic acid sodium salt is added to toothpaste to chelate Fe³⁺ on the tooth surface, preventing plaque formation and tooth discoloration (reducing tartar).
3. Industrial field: Metal processing and water treatment
Metal corrosion inhibitor: Phytic acid sodium salt. In metal processing (such as steel and aluminum products), the chelating property of sodium phytic acid enables it to form a protective film on the metal surface, inhibiting the corrosion of metals (replacing traditional chromate corrosion inhibitors and being more environmentally friendly);
Water treatment agent: In industrial circulating cooling water and boiler water, it chelates Ca²⁺ and Mg²⁺ in water, prevents the formation of scale (calcium carbonate, magnesium carbonate), and simultaneously inhibits the growth of microorganisms (assisting in sterilization).
Textile printing and dyeing: Sodium phytate, as a chelating and dispersing agent for fabrics, prevents metal ions in water from affecting the uniformity of dye coloring and enhances the printing and dyeing effect.
4. Other fields
Feed additive: Sodium phytate, when added in appropriate amounts to livestock and poultry feed, can improve the stability of the feed (prevent oxidation), but the dosage needs to be controlled (excessive use will chelate trace elements in the feed and affect animal absorption).
Cosmetics: Sodium phytate chelates metal ions in skin care products and shampoos to prevent oxidation and deterioration of the products, while reducing the irritation of metal ions to the skin.
