Application of sodium alginate in food
1. Sodium alginate can be made into various gel foods, maintaining good colloidal shape, without seepage or shrinkage, and is suitable for frozen food and artificial imitation food.
2. Can be used to cover fruits, meat, poultry and aquatic products as a protective layer, not in direct contact with the air, extending the storage time.
3. It can be used as a self-coagulating agent for sugar coating of bread, filling stuffing, coating layer of snacks, canned food, etc. It can maintain its original shape in high temperature, freezing and acid medium.
Stabilizing agent; Thickener; Emulsifier; Dispersant; Gelling agent. By industry, Suspending agent. Japan for ice cream and cold point to improve shape retention and make the tissue delicate, its dosage is 0.1% ~ 0.4%. When making fillings, give adhesiveness, and the dosage is 0.1% ~ 0.7%. Because of its hydrophilic polymer, it has strong hydration, which makes it difficult for the water adsorbed on the stabilizer to form ice crystallization. Fillings, meat sauces, gravy, frozen foods, chocolate, cream flavored hard candies, cold point gels, gel gels, syrups, emulsions, etc., used in the United States, the amount of 0.1% ~ 0.5%. In beer production as copper solidification removal agent, and protein, tannin together after coagulation removal. Can be made into film, used for candy anti-stick packaging.
Stabilizing agent. Thickener. Make artificial semi-permeable membrane. Mordant.
The biochemical level is used to fix cells and enzymes; For example, sodium alginate immobilized glutamate decarboxylase. Alginate substrates can be liquefied by the addition of chelating agents.
Application of sodium alginate in pharmaceutical preparations
1. Used in the production of suspensions, gels and concentrated emulsions based on fats and oils.
2. Used in some liquid medicines, it can enhance the viscosity and improve the suspension of solids.
3. Propylene glycol alginate can improve the stability of the emulsion.
Sodium alginate in the pharmaceutical industry
1. PSS is a kind of sodium alginate diester sodium developed with alginic acid as raw material, which has the functions of anticoagulation, lowering blood fat and lowering blood viscosity.
2. Use algae glue instead of rubber and gypsum as dental impression material, not only cheap, easy to operate, but also the tooth shape printed is more accurate.
3. Hemostatic agents of various dosage forms, including hemostatic sponge, hemostatic gauze, hemostatic film, scald gauze, spray hemostatic agent, etc.
