Gastric acid-resistant dr. kalan collagen peptide and preparation method therefor

Abstract

The present invention provides a gastric acid-resistant Dr. Kalan collagen peptide and a preparation method therefor. The collagen peptide includes a core active component, a gastric acid-resistant protective system, and functional auxiliary components. The core 5 active component is a pet-derived collagen peptide having a molecular weight ranging from 1000 Da to 3000 Da. The gastric acid-resistant protective system has a layered composite coating structure effective to provide an activity retention rate of at least 85% for the collagen peptide in a gastric acid environment. The preparation method ensures the activity and stability of the product through precise control of enzymatic hydrolysis parameters and a coating process. The product of the present invention integrates triple efficacies of promoting bone and joint repair, improving skin and coat quality, and enhancing immunity in pets.
