Fish maw collagen peptide, preparation method and application in functional beverages thereof

Abstract

The present invention discloses a fish maw collagen peptide, its preparation method, and its application in functional beverages, belonging to the field of marine bioactive ingredient extraction and application. Through the steps of softening, deodorising, enzymatic hydrolysis, deodorization, refining, and concentration, the present invention produces a low-molecular-weight fish maw collagen peptide. This peptide is then combined with anthocyanins, vitamin C, concentrated fruit juice, and excipients to formulate a product suitable for consumption as a beverage. Experimental results demonstrate that the fish maw collagen peptide and its product prepared according to the present invention can significantly improve indicators such as skin hydration, elasticity, and firmness, exhibit outstanding reparative effects on gastrointestinal mucosa, and demonstrate a synergistic effect among the fish maw collagen peptide, anthocyanins, and vitamin C. The product exhibits high sensory acceptability, safety, stable quality, and meets the requirements for large-scale production and market promotion.
