Chinese name sodium polyacrylate
English name
Chinese alias sodium polyacrylate (series)
.
Molecular formula ()
Sodium polyacrylate is a type of polyanionic polymer dielectric that has been developed in modern times and is an important chemical product with a wide range of uses. It is widely used in environmental protection, food, medicine, textile, water treatment, petrochemical, metallurgy and other sectors. Sodium polyacrylate includes two categories: water-soluble and water-swellable. Water-swellable sodium polyacrylate belongs to the category of super absorbent resin.
2. [Use of sodium polyacrylate]
Thickening agent. It has the following effects in food: enhancing the protein binding force in raw flour.
The starch particles are combined with each other, dispersed and penetrated into the protein network structure.
Form a dense dough with a smooth and shiny surface.
Form a stable dough colloid to prevent soluble starch from exuding.
Strong water retention allows moisture to be evenly maintained in the dough to prevent drying.
Improve the extensibility of dough.
Stably disperse the fat content in the raw materials into the dough.
, as the interaction between electrolytes and proteins changes the protein structure, enhances the viscoelasticity of food, and improves the tissue. , Application examples:
Bread, cake, noodles, macaroni, improve the utilization rate of raw materials and improve the taste and flavor. Dosage.%. Strengthen the structure of aquatic products, canned food, dried seaweed, etc. to maintain freshness and enhance taste
Seasoning sauce, tomato sauce, mayonnaise, jam, cream, soy sauce thickener and stabilizer.
Dispersing agent for fruit juice, wine, etc.
Ice cream and caramel sugar improve taste and stability.
Gelling agent on the surface of frozen food and aquatic products (preservation).
Since it dissolves slowly in water, it can be mixed with sugar, powdered starch syrup, emulsifier, etc. in advance to increase the dissolution speed.
Used as a clarifying agent (polymer flocculant) for sugar liquid, salt water, beverages, etc.
3. [Sodium polyacrylate method]
Stir water quickly and slowly and evenly add sodium polyacrylate powder (do not add a large amount at one time). Slowly sprinkle the rubber powder into the weighed water and do not add it. Pour water into the rubber powder, otherwise it will easily form micelles that are difficult to dissolve.) Stir for a few minutes until the particles are swollen and suspended, then stand still for an hour to dissolve. Due to its extremely large molecular weight, the solubility concentration of this product is generally not exceeded.
. The viscosity of sodium polyacrylate of the same specification differs greatly when water with different water qualities (soft water, hard water) dissolves it. It is recommended to dissolve in soft water.
Influence of salt concentration: The viscosity of sodium polyacrylate decreases with the increase of salt concentration.
4. [Product Packaging]
The outer packaging is made of kraft paper bags lined with high-pressure polyethylene film bags. Kilogram/bag can also be packaged according to customer agreement.
