A method of preparing the composition of natural vitamin C and a fish scale collagen peptide comprising following steps:
- (1) adding ultrapure water into a formula amount of the fish scale collagen peptide to prepare an aqueous solution;
- (2) adding a pH regulator into the aqueous solution of the fish scale collagen peptide to adjust a pH value to 5-7;
- and adding, under a negative pressure condition, a formula amount of the natural vitamin C to prepare a mixed solution of the natural vitamin C and the fish scale collagen peptide;
- (3) concentrating the mixed solution, obtained in the step (2), under a negative pressure to give a concentrate of ¼-½ of an original volume;
- and (4) cold drying, freeze drying or spray drying the concentrate under a negative pressure condition, to give the composition of natural vitamin C and the fish scale collagen peptide.
