The present application relates to the technical field of bioactive peptides, and in particular to an oat
oligopeptide, preparation thereof and application thereof in preparing a product for regulating the expression of brain
appetite suppressor factor. The oat
oligopeptide can effectively stimulate the release of
cholecystokinin (CCK) from intestinal endocrine cells, and stimulate the
central nervous system through the
vagus nerve pathway, thereby promoting the expression of the
appetite suppressor factor pro-opiomelanocortin (POMC) in the
hypothalamus. Compared with the prior art, the oat
oligopeptide has the advantages of stable structure, high safety, simple preparation process (conventional
enzymatic hydrolysis and chromatographic purification can achieve the preparation), easy scale production and the like. The oat oligopeptide is suitable for being used as a functional ingredient or a
drug precursor to develop a related health product with the functions of regulating
appetite and promoting satiety, and has a wide application prospect in the field of preparing functional products (food,
medicine and the like).
