Embodiment Construction
[0016] A preparation method of yak bone collagen peptide, the process steps include raw material pretreatment, gelatin extraction, separation of collagen extract, compound enzymolysis, enzyme sterilization and sterilization, separation of peptide liquid, decolorization and deodorization, concentration and drying, specific steps yes:
[0017] (1) Pretreatment of raw materials: Rinse fresh or frozen yak bones with high-pressure cold water to remove foreign matter, then put the cleaned yak bones into a grinder, crush them to a size of 20-30mm, and place them in a clean container;
[0018] (2) Gelatin extraction: accurately measure the yak bone and put it into the cooking tank, add 1.2 times the weight of the yak bone through a pipeline flow meter, close the feeding port, and cook in hot water to form a mixture containing oil and gelatin;
[0019] (3) Separation of collagen extract: after the extraction, open the drain valve at the bottom of the cooking tank and the feed valve of ...

Abstract
The invention discloses a preparation method of yak bone collagen peptide. The method is characterized by comprising the following technological processes: pretreatment of raw materials, gelatin extraction, separation of a collagen extracting solution, composite enzymatic hydrolysis, enzyme deactivation and sterilization, separation of a peptide solution, decoloring and deodorizing, concentrating and drying. The compound enzyme for composite enzymatic hydrolysis is prepared from protease, amylase, pectinase, cellulose and xylanase. The method has the advantages that the gelatin extraction process is simple, oil and gelatin are completely separated by using flow of a mixed solution, the enzymatic hydrolysis temperature is 48-52 DEG C, the time is 4-6 hours, the temperature is reduced in comparison with common enzymatic hydrolysis temperature, the preparation time of the product is shortened, and the method comprises enzyme deactivation and sterilization procedures, and decoloring and deodorizing procedures, so that the product is good in taste, and applicable to preparation of the yak bone collagen peptide.
Description
technical field [0001] The invention belongs to medical preparations derived from mammals, in particular to a collagen peptide health food made from yak bones. Background technique [0002] Qinghai is rich in yak bone resources. In recent years, it has developed basic biochemical raw materials such as bone meal, gelatin, peptone, yak chondroitin, and health food such as yak bone marrow powder. According to the determination of atomic absorption spectroscopy, yak bones contain K, Na, Ca, Mg, P, Cu, Zn, Fe, Mn, Ni, Pb, Cd and other 12 mineral elements, which play an extremely important role in the growth and development of human bones . [0003] Although there are many health foods made of yak bones, the preparation method is generally to cook the yak bones at high temperature, pulverize, degrease the soup, grind, sterilize, homogenize, concentrate, and spray-dry to make powder. The technological process fails to make small molecules of protein, and the nutritional component...
