Application

  1. the thickening agent. In food has the following function:(1) enhance the raw material of flour proteins in cohesive force.(2) the starch particles combined with each other, permeate into the reticular structure of protein

    (3) forming dense texture of the dough, the surface smooth and with luster.

    (4) to form stable dough colloid to prevent soluble starch.

    (5) strong water retention, keep moisture evenly in the dough, prevent dry.

    (6) improve the ductility of the dough.

    (7) the raw material of the grease composition steadily disperse into the dough.

  2. As electrolyte and protein interaction, change of protein structure, enhance the viscoelasticity of food, improve the organization.
  3. Industrial sodium polyacrylatea. High relative molecular mass for flocculating agent. Water treatment agent, flocculantb. paper chemicals

    c.Making plugging agent for oil field

Utility for food: To enhance the protein in raw material powder binder force. The starch particles together, scattered into the mesh structure of protein. Make raw material (dough) forming dense surface bright and clean. Make raw material (dough) stability of colloid, and thus avoid the leakage of soluble starch. The moisture in wet sex is very strong, make the raw material uniform distribution, prevent dry. To enhance the ductility of the material. Grease composition is uniformly distributed in the raw powder, maintain its stability
