摘要
采用分光光度法测定鱼皮(鱿鱼皮和狗鲑鱼皮)中的羟脯氨酸(Hyp)含量具有较高的准确度和精密度。采用该法测定两种鱼皮中羟脯氨酸的含量分别为0.823%和2.247%,平均回收率分别为98.47%和98.39%,变异系数分别为1.65%和0.64%。该法重复性好,可信度高,可作为判定鱼皮中胶原蛋白含量的一个定量指标。
Hydroxyproline（Hyp） content in fish skins was determined by the spectrophotometric method. Spectrophotometric method has high veracity and precision. The Hyp contents of squid skin and chum salmon skin were 0.823 % and 2.247 %, respectively. The average recovery rates and the CV of Hyp from squid skin and chum salmon skin were 98.47 % and 98.39 %, and 1.65 % and 0.64 %, respectively. This method can be used as a reliable quantitative method of the collagen in fish skins.
