Casein is a non-crystalline, non-hygroscopic substance, 0.8-1.2% soluble in water at room temperature, slightly soluble in water and organic solvents at 25°C, soluble in dilute alkali and concentrated acid, and can absorb water. Expands rapidly, but mosquitoes do not bind.

Casein is a phosphorus-containing protein in animal milk. The structural formula is NH2RCOOH, an odorless, tasteless white to yellow powder with a relative density of 1.25-1.31. Almost insoluble in water, alcohol and ether. Soluble in dilute lye, alkaline carbonate solution and concentrated acid, and precipitate in weak acid. Hygroscopic, stable when dry, and hardens quickly when wet.

1. Thickeners; Emulsifiers; Stabilizers; Nutritional Fortifiers; Binders; Fillers; Carriers. Limit: 0.3%-0.7% of ice cream; 1%-3% of meat products and aquatic meat products; 5% of protein fortified bread and biscuits; 3% of mayonnaise.

2. Acid casein is mainly used as a base material for coatings, adhesives for wood, paper and cloth, food additives, etc. As the base material of the coating, it accounts for about half of the total consumption. It has excellent water resistance and can be well dispersed in the pigment to improve the uniformity of the coating. In addition, rennet 2 protein is mainly used in the manufacture of plastic buttons due to its good fluidity and ease of application. Compared with other resin buttons, casein buttons have good dyeability, processability and bright color, and the quality is in the middle of the buttons. Casein is evenly mixed with slaked lime, sodium fluoride and copper sulfate, and then mixed with kerosene to obtain casein glue, which is a kind of adhesive used in aviation industry and wood processing departments. Casein is also used in medicine and biochemical reagents.

3. Hygroscopic, used as wood glue, paper coating, diabetic food, biological material, textile pulp, etc.

4. Used as a biochemical reagent
