More Information
Summary:The invention aims at providing collagen powder rich in collagen tripeptide and a preparation method thereof. The preparation method comprises the following steps of: firstly extracting fishskin collagen from fishskin serving as a raw material by adopting compound protease, and degrading fishskin collagen into micromolecular peptide; then further directly degrading the micromolecular peptide into the collagen tripeptide by utilizing autonomously-screened collagenase; and then carrying out centrifugalization, deodorization, decolouration, concentration and spray drying to obtain the collagen powder rich in collagen tripeptide. According to the preparation method provided by the invention, fishskin with low fat content is used as the raw material and the procedure that the fishskin is soaked in a dilute alkalis solution to remove fat is omitted in a preparation process, thereby decreasing the harmful substances generated due to acid and alkali treatment. Besides, commercially available protease is used for carr
