Abstract
This invention discloses yak milk small molecule peptides and their preparation method. The preparation method of yak milk small molecule peptides achieves precise cleavage of proline-rich regions by specifically recognizing specific proline-rich regions in yak milk proteins, thus solving the technical challenge of enzymatic cleavage of proline regions. Furthermore, by establishing a triple control mechanism of gentle defatting, antioxidant protection, and phospholipase synergistic action, the oxidative off-flavor caused by the high fat content of yak milk is avoided. This invention also discloses yak milk small molecule peptides prepared by the above method, with a yield of 87.5% ± 2.5% for 2-3 amino acid small molecule peptides and a conjugated linoleic acid retention rate of 95.0%–97.0%.
