It is a kind of high molecular polymer with hydrophilic group. It appears odorless and tasteless white powder or granule. It will form transparent solution of great viscosity while slowly dissolved into water. The viscosity is engendered by the dissociation of numerous anions and hence causes the growth of molecular chain not by expansion of water absorption that normally happens to CMC and sodium alginate. The viscidity is about 15~20 times higher than CMC and sodium alginate. It shows high alkali-resistant, minor change in viscosity after longtime storage, and not easily decaying.
4.PAAS for edible application examples
Noodle industry (flour, noodle, bread, Dumpling wrappers, wonton wrappers,tang-yuan) style="text-indent: 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.
5. Packing and storage:
1)Packed in net 25kg polywoven bag lined with well-sealed PE inner bags. Pretected from moisture and avoid contact with acid, alkaline and metal ions.
Mainly application area:
(1) food manufacturing sodium polyacrylate could use for thickening: emulsification, figuration.
swelling,steady, the viscosity is 15-20 times higher than carboxymethyl cellulose sodium and sodium alginate can replace the role of CMC,
gelatin, agar, sodium alginate and reduce costs,increase food grade, improve the taste and extend the retention period; as the thickener,
it can be use for many kinds of food, the addition we suggested is 0.1%-1.2%
The following are examples :
a Noodle industry Flour products like instant noodle, noodle, various types of flour,bakery food and so on.Enhance the protein cohesive
force of flour,prevent the soluble starch and nutrients emulation, improve dough extensibility and raw material utilization.To improve the
taste and flavors,control of dry bread and other food products caused by natural drying. In the deep-fried food processing, like instant noodle, to spread fat of raw materials steady in dough, decrease oil absorption rate and save oil.
b. Beverage industry as a compound emulsion stabilizer ingredient components, replace the role of CMC gelatin,agar and so on, play
enhancement effect and reduce the cost.
