中文摘要:
      本实验旨在建立明胶中L-羟脯氨酸测定的方法。采用比色法对明胶中的L-羟脯氨酸含量进行测定,结果表明,本方法的检出限为0.26 g/100g,回收率为92.59%~101.25%,RSD为1.42%,可用于明胶中L-HYP含量的测定。
英文摘要:
      This study aim at developing a method to detect L-hydroxyproline(L-HYP) in Gelatin.The Lhydroxyproline content in Gelatin was determined by colorimetiy mehod in this study.The result shows that detection limit of this method is 0.26 g/100g;the recovery ratios and RSD are 92.59%~101.25%and 1.42%,respectively.The method is suitable for the determination of L-HYP in Gelatin.
