油菜籽榨油后剩下的约60％饼粕,其中含蛋白质约35％,是优良的畜禽饲料。但饼粕中含有3—8％的多种硫代葡萄糖甙(下称芥子甙)在菜籽中的芥子酶作用下生成异硫氰酸酯(ITC)、恶唑烷硫酮(OZT)和腈类等有毒化合物,限制了饼粕的有效利用。为了利用这些蛋白质资源,国内外开展饼粕脱毒研究已有20多年的历史,但关于饼粕化学脱毒产物的定性分析的报道还不多见。为此,我们采用GC/MS/DS联用技术,对饼粕中芥子甙
Approximately 60% of the remaining meal after rapeseed oil extraction contains about 35% protein, which is an excellent feed for livestock and poultry. But the meal contains 3-8% of various glucosinolates (hereinafter referred to as mustard glycosides) in the rapeseed enzyme generated isothiocyanate (ITC), oxazolidine thione (OZT) and Nitrile and other toxic compounds, limiting the effective utilization of cakes. In order to utilize these protein resources, the researches on detoxification of mucopolysites have been carried out for more than 20 years at home and abroad. However, the reports on the qualitative analysis of chemical detoxification products of mucilage are rare. To this end, we use GC / MS / DS combination technology, the gluten in the cake
