Abstract

The invention relates to functional peanut small molecule mixed polypeptide, a preparation method and application thereof, belonging to small molecule mixed polypeptide generated by peptide chain hydrolysis.The invention is characterized in that the functional peanut small molecule mixed polypeptide is prepared by adopting the following raw material components by weight part: 100 parts of defatted peanut cake, 6-10 parts of combined enzyme preparations, 6-12 parts of active carbon, 3-8 parts of diatomite, 3-8 parts of pearlite and 100 parts of water; and the following technical indexes are achieved: the molecular weight distribution range Dalton (D) is less than or equal to 3000, the content of the small molecule mixed polypeptide is more than or equal to 80wt, the total nitrogen is more than or equal to 12wt%, the water solubility is 90wt%, the water is less than or equal to 5wt%, and the fat is less than or equal to 0.5wt%.The invention provides a product of the functional peanut small molecule mixed polypeptide with high purity, good solubility, average molecular weight of less than 3000D and strong biological functionality and a preparation method of the functional peanut small molecule mixed polypeptide with short production cycle, high product yield and low preparation cost. The functional peanut small molecule mixed polypeptide is suitable for a raw material of medicines, health food and beverage and functional nutritious food.

Description

technical field [0001] The invention is a functional peanut small molecule mixed polypeptide and its preparation method and application. It belongs to the small molecule mixed polypeptide produced by the hydrolysis of peptide chain. Background technique [0002] Peanut protein is a high-quality plant protein with high nutritional value. It contains 8 kinds of so-called "essential amino acids" that cannot be synthesized in the human body or cannot be synthesized in sufficient quantities, and must be obtained from food. It is also rich in "semi-essential amino acids" The arginine contained in it plays an important role in maintaining human health, improving immune function, and promoting the development of young children. Modern studies have shown that polypeptides are absorbed more easily and quickly by the human body through the small intestine. In particular, small molecule peptides can be absorbed directly from the intestinal tract without degradation. In addition, the ...
