【摘要】 用比色法测定鱼鳞中的羟脯氨酸 ( Hyp) ,具有较好的稳定性和较高的回收率。鱼鳞经过脱钙处理 ,羟脯氨酸的保留率为 96.1 9% ,经过第一次提取胶原蛋白后 ,提取率达到了总胶原蛋白的 70 %以上 ,同样的条件下进行第二次提胶 ,二次胶原蛋白的提取率较低更多还原

【Abstract】 The Hydroxyproline (Hyp) content in the fish scales was determined by the photocolorimetric method in this paper. The determination method is stable with a high yielding rate. After the de-calcification of the fish scales, the retaining rate of Hyp is 96 19%. The extract yield of Hyp from fish scales is more than 70% of the total collagen in the first time. However, under the same condition, the extract yield in the second time is rather low.更多还原
