Abstract

The invention relates to the technical field of deep processing of animal protein, and particularly relates to a preparation method and application of ternary polypeptide nanoparticles based on yak bone peptide. The preparation method of the ternary polypeptide nanoparticles based on the yak bone peptide comprises the following steps of: mixing the yak bone peptide, rice protein and casein with water to obtain a mixed system; adjusting the pH of the mixed system to be greater than or equal to 11 by adopting an alkaline solution; and after hydration, adjusting the pH of the hydrated system to be 6-8 by adopting an acidic solution, so that the protein is combined in a common frame manner. The nanoparticles with the particle size of 50-200nm can be prepared by utilizing the method, the particle size uniformity is high, and the nanoparticles have good solubility and stability; and meanwhile, according to the method, on the basis of retaining the integrity of the primary structure of the protein to the maximum extent, the secondary structure of the protein is changed through interaction, nutrition complementation is achieved through combination of different proteins, and the potential value of the yak bone peptide is improved.

Description

technical field [0001] The invention relates to the technical field of animal protein deep processing, in particular to a preparation method and application of yak bone peptide-based ternary polypeptide nanoparticles. Background technique [0002] In recent years, the rapid economic development has promoted the improvement of living standards. People's dietary requirements no longer stay at the stage of filling their stomachs. A healthy and reasonable diet has become the mainstream of people's pursuit. Protein is an important part of the daily diet, and it is necessary to ensure a certain amount of high-quality protein intake every day. However, the current supply of protein, especially the supply of high-quality protein, is still insufficient. [0003] At the same time, animal slaughter products are rich in resources, and livestock and poultry bones are not fully utilized as by-products in meat production, and a large amount of high-quality protein is wasted. Among them, ...
