Abstract
To predict the nutritional quality of seafood proteins using a newer in virto model, 10 species of shellfish protein samples were used in determining the extent of in vitro digestibility, trypsin indigestible substrate (TIS), computed protein efficiency ratio (C-PER), discriminant computed protein efficiency ratio (DC-PER) and predicted digestibility which calculated solely from amino acid profile. The content of TIS in eviscerated samples were ranged from 1.10 to 5.09 mg/g solid, whereas the whole samples were ranged from 1.26 to 7.30 mg/g solid expressed quantitatively as mg of soybean trypsin inhibitor. The in vitro digestibility showed
한국산 10종의 패류단백질을 선정하여 이들의 in vitro 소화율과 trypsin 비소화성 물질을 정량하고, 아미노산 분석결과를 같이 이용하여 이들 단백질의 품질을 C-PER technique 으로 평가하였으며 이를 토대로 패류단백질 품질평가를 위하여 적용가능 한 in vitro technique이 선정되었다. In vitro 소화율은 대부분의 시료가 어류단백질보다 낮은
