초록
본 연구는 가자미껍질에서 콜라겐 펩타이드 파우더(FSCP)를 제조하여 시판 틸라피아비늘 유래 콜라겐 펩타이드 파우더 (TSCP)와 이화학적 특성을 비교 검토하였다. FSCP의 물리적인 특성 및 영양성분은 TSCP와 유사하게 나타났으며, 열량에 있어서도 FSCP는 3.82 kcal로 TSCP의 3.84 kcal와 차이가 없는 것으로 나타났다. 아미노산 조성은 FSCP가 TSCP보다 aspartic acid, serine, histidine, tyrosine, methionine의 경우 높았으나, hydroxyproline, proline, alanine은 오히려 낮았다. 특히 필수아미노산 함량은 FSCP가 22.74%로, TSCP의 13.64%보다 높았다. 분자량 분포는 FSCP가 1000 Da 으로, TSCP에 비하여 비교적 낮은 분포를 보이고, 유화성 및 유화안정성은 FSCP와 TSCP가 유사한 경향으로 우수하였다.
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.
