In this research, the collagen peptide powder from flatfish skin (FSCP) was prepared and compared with commercial collagen peptide powder from tilapia scale (TSCP) in the aspect of physiochemical property. The physical property and nutritional components of FSCP appeared almost similarly to those of TSCP, and also in calorie. No differences in calorie between FSCP and TSCP. Amino acid contents of FSCP for example, aspartic acid, serine, histidine, tyrosine and methionine were higher than those of TSCP. In contrast, the hydroxyproline, proline, alanine contents in FSCP were lower than those in TSCP. Especially, the content of essential amino acid of FSCP, which was 22.74%, was higher than that of TSCP evaluated as 13.64%. In the distribution of molecular weight, FSCP was 1000 Da, which showed a comparatively low distribution compared with TSCP, and in emulsion property and stability both FSCP and TSCP showed an excellent trend.
