Sodium Polyacrylate(PAAS) is a water-soluble macromolecule compound with strong function of thickening and water retention. It has high purity, stable performance, no smell, no smell and no corruption for a long time. It is beautiful

Food additives approved by FDA, ministry of health of Japan and ministry of health of China are harmless to human body and easy to preserve and store.


(1) Noodle industry (flour, noodle, bread, dumpling wrappers, wonton wrappers, tang-yuan). PAAS can enhance protein adhensive of flour and prevent soluble starch and nutrient from seepage. It can make dough more extensive, improve the texture and taste, inhibit bread and other food from drying caused by natural aging. In the fried food, such as instant noodles, PAAS can make oil fully dispersed in the dough, reduce the absorption rate of oil and save oil.

(2) Bean vermicelli, bean noodles, bean sheet jelly PAAS can highly increase the flexibility and boiling fastness of vermicelli, bean starch sheets made from sweet potato, corn, oat, potato,etc.

(3) Ice industry. As a mixed emulsifier stabilizer and dispersant composition of the ingredients, it can partially replace guar gum,CMC, and so on.. Enhance the effect at lower costs.

(4) Meat products. It is used for meat processing, such as sausage, meatballs, artificial meat, increasing the viscosity and ductibility of protein fibers and taste.

(5) Cream and jam. PAAS can be used as thickener and stabilizer in flavoring source, ketchup, jam and cream,improving its taste and texture and maintaining its shape for long time.
