当前国内外油菜科研、生产和市场的特点是高度重视品质。优质油菜目前主要指单低(低芥酸)、双低(低芥酸、低硫代葡萄糖甙)油菜。国际标准对双低的要求是芥酸含量5％(约为普通油菜的1/10)以下、硫甙3‰(约为普遍油菜的1/5)以下。芥酸不易为人体消化吸收,降低芥酸含量的同时,增加了对人体健康有益的亚油酸和油酸含量提高了菜籽油的营养价值。莱籽饼含优质蛋白质40％左右,但有毒性,通常只用来肥田,低硫甙菜籽饼无毒,可代替粮食作高蛋白精饲料,使其转化为畜禽产品和全效性有机肥料。此外,油菜品质改进
At present, the characteristics of rapeseed research, production and market both at home and abroad are to attach great importance to quality. High-quality rape mainly refers to single low (low erucic acid), low (low erucic acid, low glucosinolates) rape. International standards for double low requirements of erucic acid content of 5% (about 1/10 of ordinary rape) the following, glucosinolate 3 ‰ (about 1/5 of the common rape) the following. Erucic acid is not easy for the human body to digest and absorb, reducing erucic acid content, while increasing human health beneficial linoleic acid and oleic acid content increased rapeseed oil nutritional value. Lai seed cake containing about 40% of high quality protein, but toxic, usually only used for fertilizer, low glucosinolate rapeseed cake non-toxic, can replace food for high protein concentrate feed, make it into livestock products and full-effect organic fertilizer. In addition, rapeseed quality improved
