Abstract

Gelatin from salmon () skin with high molecular weight protein chains (-chains) was extracted using trypsin-aided process. Response surface methodology was used to optimise the extraction parameters. Yield, hydroxyproline content and protein electrophoretic profile via sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis of gelatin were used as responses in the optimization study. The optimum conditions were determined as: trypsin concentration at 1.49 U/g; extraction temperature at 45 °C; and extraction time at 6 h 16 min. This response surface optimized model was significant and produced an experimental value (202.04 ± 8.64%) in good agreement with the predicted value (204.19%). Twofold higher yields of gelatin with high molecular weight protein chains were achieved in the optimized process with trypsin treatment when compared to the process without trypsin.

摘要

采用胰蛋白酶辅助法从三文鱼皮中提取具有高分子量蛋白质链(-链)的明胶。运用响应面法优化提取参数。在优化研究中,将明胶的产率、羟脯氨酸含量以及通过十二烷基硫酸钠-聚丙烯酰胺凝胶电泳分析得到的蛋白质电泳图谱用作响应指标。确定的最佳条件为:胰蛋白酶浓度为1.49 U/g;提取温度为45℃;提取时间为6小时16分钟。该响应面优化模型具有显著性,实验值(202.04±8.64%)与预测值(204.19%)吻合良好。与未使用胰蛋白酶的工艺相比,在优化后的胰蛋白酶处理工艺中,具有高分子量蛋白质链的明胶产量提高了两倍。
