Embodiment 1

[0012] A kind of amino acid-rich bovine bone powder and preparation method thereof, it comprises the following steps:

[0013] (1) Preparation of bone broth: take fresh beef bones, wash them with water and remove the remaining meat and foreign matter on the surface; crush the cleaned beef bones, and use a high-speed universal grinder to crush them into 2-3cm bone pieces; weigh the bone pieces, Add distilled water at a bone-to-water ratio of 1:2, place in a high-pressure reaction axe, and cook the bone at room temperature under high pressure at a temperature of 25°C and a pressure of 0.1MPa. After cooking for 3 hours, filter to remove the bone residue, and take the filtrate at 4°C. Freeze for 36 hours, remove the upper layer of fat, and use a low-temperature refrigerated centrifuge to centrifuge at 5000r / min at 4°C for 30 minutes to obtain the supernatant to obtain bone broth;

[0014] (2) Proteolysis solution: put the bone broth prepared in step (1) in a hydrolysis tank at a t...

Abstract

The invention discloses amino acid-enriched bovine bone powder and a preparation method thereof. The invention relates to the technical field of bovine-resource product deep-processing, and especially discloses amino acid-enriched bovine bone powder which is prepared by deep-processing the bovine bones and a preparation method thereof. A purpose of the amino acid-enriched bovine bone powder is to solve the problems of insufficient developments and utilizations of the fresh bovine bone resources; and the fresh bovine bone resources are deeply developed by modern science and technology, so that the bovine bone can be better absorbed and utilized by the human body. The amino acid-enriched bovine bone powder is successfully prepared from the fresh bovine bones by a normal-temperature high-pressure steam-cooking method and a double-enzyme fractional degradation method. The prepared amino acid-enriched bovine bone powder is high in protein content and strong in antioxidant activity; and the amino acid amount is no lower than 27.54%, which is 34.33-40.34% higher than the amino acid amounts of unprocessed bovine bones, so that the amino acid-enriched bovine bone powder is high in biological values. Thus, the amino acid-enriched bovine bone powder can be taken as a good source of high-quality human proteins.

Description

technical field [0001] The invention provides an amino acid-rich bovine bone powder and a preparation method thereof, relates to the technical field of deep processing of bovine resource products, and belongs to the field of biology. Background technique [0002] The bovine bone is the skeleton of a yellow ox or a buffalo, an animal of the genus Buffalo in the family Bovidae. Bone is rich in nutritional value. In my country, the bones of vertebrates have a long history of medicinal use, which is recorded in "Compendium of Materia Medica" and "Journal of Materia Medica". A large number of experimental studies have shown that: the amino acids that make up protein in bone are complete and balanced in proportion, and the proportion of essential amino acids is relatively high, which belongs to high-quality protein; bone also contains phospholipids, phosphoproteins, and choline, which are indispensable for brain development Nutrients, collagen, chondroitin, etc. can enhance subc...
