Conclusion Under the optimized fermentation conditions,the degree of hydrolysis of rapeseed meal protein reached 13.1% with high contents of free amino acids and small peptides.

结论发酵过程参数优化后的菜粕蛋白水解度达到了13.1%,增加了游离氨基酸和小肽含量。

It is only used for animal feed and fertilizer ,thus leading to the waste of resources. Therefore,it's significant to work on the value-added process of rapeseed meal.

因此对菜籽饼粕的升值加工是一项重要的应用研究工作。

Rapeseed meal is a by-product of oil extraction ,which is formed after the squeezing and defatting process. The content of total protein reaches 28%-40% and can be exploited as food additive because of its good quality.

菜籽粕是菜籽榨油过程中经压榨脱脂后产生的一种副产物,其粗蛋白含量一般为28～40%,为全价优质的植物蛋白。

The main results are as follows:(1) In this paper, we found that Rapeseed Meal does contain genistin which is one of the isoflavones by extraction of rapeseed meal. and the content range of genistein is 0.100%-0.290%.

其主要实验结果如下：(1)本文发现油菜饼中含有异黄酮类化合物为染料木素(genistin)，油菜饼中染料木素的含量范围为0.100％—0.290％。
