摘要: 为了提高鹿托盘中胶原蛋白的提取率,采用高压脉冲电场技术辅助胃蛋白酶的方法提取胶原蛋白。以胶原蛋白提取率为指标,通过对胃蛋白酶添加量、脉冲数和电场强度进行单因素考察,采用正交实验对胶原蛋白提取条件进行优化。优选出鹿托盘胶原蛋白的最佳提取条件为:胃蛋白酶添加量2%、脉冲数8、电场强度20 kV.cm-1,在该条件下鹿托盘胶原蛋白的提取率可达到(73.27±0.73)%。与普通酶法相比,高压脉冲电场辅助提取胶原蛋白的得率比普通酶法提高了10.34%,且处理时间较短。聚丙烯酰氨凝胶电泳结果表明所提取的胶原蛋白由α1、α2和β-亚基组成,结构特征表明胶原蛋白具有完整的螺旋结构和Ⅰ型胶原蛋白的特性。该研究可为高压脉冲电场用于胶原蛋白的提取提供理论参考。

Abstract: In order to find out the optimal extraction conditions of collagen from antler base,high intensity pulsed electric fields(PEF)-assisted pepsin methods were applied in this study.With the collagen withdrawal rate as the evaluation indicator,the effects of pepsin content,pulse number and electric field strength on extraction of collagen were studied,and the orthogonal test was designed to optimize the extraction conditions.The optimal collagen extraction conditions were determined: pepsin content 2%,pulse number 8 and electric filed strength 20 kV.cm-1,and the withdrawal rate of antler base collagen was(73.27±0.73)%.Compared with enzymatic methods,PEF-assisted extraction was less time-consuming with higher extraction efficiency.The result of SDS-PAGE confirmed that the subunits structure of pepsin-soluble collagen from antler base using PEF was mainly of α1、α2 and β.The collagen from antler base greatly maintained the characteristics of type Ⅰ collagen and with intact triple helix structure.This design can provide some reference to the extraction of collagen by PEF.

Key words: antler base, collagen, high intensity pulsed electric fields, orthogonal test
