Abstract

The invention discloses a peptide-containing milk and process for preparation. The milk of the invention is processed through charging thymus polypeptide extract extracted from fetal bovine thymus tissue into common milk, and then processing through homogeneous process. During preparing the thymus polypeptide extract, steps of homogenate, freezing and thawing, interception, filtering and the like are employed, thereby processing thymus polypeptide extract with molecular weight < 30000 Daltons. A lot of experiments prove that the peptide-containing milk of the invention has the functions of enhancing immunity and stimulating stem cells to proliferate.

Description

technical field [0001] The invention relates to a peptide milk and its preparation process, in particular to a milk containing thymus polypeptide extract and its preparation process. Background technique [0002] There are diet therapy and medicated diet in ancient Chinese traditional medicine, which have lasted for thousands of years. Developed industry promotes social and economic progress while bringing negative impacts. The deterioration of the living environment, the aggravation of air and water pollution, and the tense and fast-paced modern lifestyle have invisibly promoted malignant tumors, hyperlipidemia, and high blood pressure. , the occurrence of arteriosclerosis, diabetes, obesity, etc. and the existence of a large number of sub-healthy people. It stimulates people to pay more attention to their own health and survival, and requires some special functional foods to regulate body functions and increase resistance to diseases. Health food is a new type of food, a...
