芝麻饼(渣)蛋白硒性质及提取条件的研究

The Properties and Extraction Conditionsof Protein-Selenium in Sesame Cake(Meal)

本文研究了芝麻饼（渣）中含硒量、生物效能、溶解性、分布及存在形式等性质。用Ｄ型大柱凝胶电泳分析其可溶性蛋白硒络合分子量范围为２１ＫＤ～３０ＫＤ。提取条件效应综合预测数学模型为：Ｙ１＝０．４６４７Ａ＋１０．０６３７Ｃ＋３６．８１４５Ｄ＋０．１５６７Ｅ－３２．７８４８Ｙ２＝０．００６８Ａ＋０．００２５Ｂ－０．４２５０Ｄ＋０．

The content,biological function,solubility,distribution and forms of Se in sesame cake were investigated.D-sized column PAGE was used to determine the molecular weight range of complex Se,which was found to be 21～30 KD,and the forecasting mathematic model for extraction was as follows:Y1=0.4647A+10.0637C+36.8145D+0.1567E-32.7848Y2=0.0068A+0.0025B-0.4250D+0.1670
