With the increasing consumption power of people, food is becoming more and more colorful. Food moisture retention agent plays an important role in food industry. Sodium tripolyphosphate is one of the food additive water retention agents.

Water retention agent of food is a kind of food additive which is helpful to keep the stable water content in food. It belongs to the quality improver, mainly refers to the phosphate used in meat and aquatic products processing to enhance water stability and improve water retention. Condensed phosphates are hydrophilic substances, which can stabilize the water content in food.

Food additive sodium tripolyphosphate can improve the PH value of meat, chelate the metal ions in meat and increase the ionic strength of meat. Dissociation of some meat proteins can keep the maximum water content of meat products, improve the binding power, tenderize the meat quality and maintain more nutrients. It is an important additive for meat products, especially for minced meat, sausage, meat stuffing, etc.

Sodium tripolyphosphate is hydrolyzed in aqueous solution. The hydrolysis rate varies with the temperature and PH of the solution. The hydrolysates are pyrophosphate and right acid salt. The addition of sodium tripolyphosphate in the internal food can improve the product quality, such as regular appearance, fresh meat, bright color, etc. It can separate calcium pectinate and calcium oxalate on the surface of fruits and vegetables, and promote the softening of skin.

Water retention agent of food additive sodium tripolyphosphate adds luster to life. The water retention agent sodium tripolyphosphate produced by Chongqing Chuandong Chemical Group has stable quality and few impurities.
