Utilize dairy products deep-processing to prepare casein's device

Technical Field

The utility model relates to a dairy products deep-processing technical field, in particular to utilize dairy products deep-processing to prepare device of casein.

Background

Casein is the major protein in mammalian milk, including cow, sheep and human milk. The protein of milk is mainly casein, and the protein of human milk is mainly albumin. Casein is a large, hard, dense curd that is extremely difficult to digest and break down. Casein is the protein with the highest content in milk, is mainly used as a food raw material or a microorganism culture medium at present, casein phosphopeptide prepared by utilizing a protein enzymatic hydrolysis technology has various physiological effects of preventing mineral loss, preventing decayed teeth, preventing and treating osteoporosis and rickets, promoting the in vitro fertilization of animals, regulating blood pressure, treating iron-deficiency anemia, magnesium-deficiency neuritis and the like, and particularly can promote the high-efficiency absorption of macroelements (Ca and Mg) and microelements (Fe, Zn, Cu, Cr, Ni, Co, Mn and Se).

Casein is non-crystalline and non-hygroscopic substance, can be dissolved in water at room temperature by 0.8-1.2%, is slightly soluble in water and organic solvent at 25 deg.C, can absorb water, and can rapidly swell when immersed in water, but the molecules are not bonded.
