<Abstract>
<AbstractText Label="BACKGROUND" NlmCategory="BACKGROUND">Sturgeon (Acipenser sturio Linnaeus) skin contains high amount of nutrients including unsaturated fatty acids and collagen. A pepsin-assisted extraction procedure was developed and optimized for the extraction of collagen from Chinese sturgeon (Acipenser sturio Linnaeus) skins.</AbstractText>
<AbstractText Label="OBJECTIVE" NlmCategory="OBJECTIVE">To determine the optimum conditions with the maximum yield of the pepsin-soluble collagen (PSC) extraction.</AbstractText>
<AbstractText Label="MATERIALS AND METHODS" NlmCategory="METHODS">The conditions of the extraction were optimized using response surface methodology. The Box-Behnken design was used to evaluate the effects of the three independent variables (extraction time, enzyme concentration, and solid-liquid ratio) on the PSC yield of the sturgeon skin.</AbstractText>
<AbstractText Label="RESULTS" NlmCategory="RESULTS">THE OPTIMAL CONDITIONS WERE: solid-liquid ratio of 1:11.88, enzyme concentration of 2.42%, and extraction time of 6.45 h. The maximum yield of 86.69% of PSC was obtained under the optimal conditions. This value was not significantly different from the predicted value (87.4%) of the RSM (P < 0.05).</AbstractText>
<AbstractText Label="CONCLUSION" NlmCategory="CONCLUSIONS">The results of this study indicated that the production of PSC from sturgeon skin is feasible and beneficial. The patterns of sodium dodecyl sulfate-polyacrylamide gel electrophoretic patterns (SDS-PAGE) indicated that the sturgeon skin contains type I collagen, which is made of α-chain and β-chain. The infrared spectra of the collagens also indicated that pepsin hydrolysis does not affect the secondary structure of collagen, especially triple-helical structure.</AbstractText>
