发展优质油菜,改善食油营养价值,成为油菜生产的发展趋势。我省从80年代开始大面积试种低芥酸油莱,1985年种植面积28.05万亩,1986年秋种植面积16.44万亩,已逐步扩大到全省许多市县。 一、优质油菜及其营养价值 食用菜籽油的品质是由脂肪酸组成所决定的,它的主要成份有:油酸、亚油酸、二十碳烯酸、亚麻酸、芥酸等。其中芥酸含量高,营养价值就会降低,亚麻酸含量高容易酸败,不耐贮藏。普通油菜,芥酸含量为40~53%,亚麻酸含量约为10%,而国
The development of high quality rape, improve the nutritional value of cooking oil, rape production has become the development trend. Since the 1980s, our province has been experimenting with a large area of low erucic acid Lailai, planting area of 285,500 mu in 1985 and planting area of 164,400 mu in the autumn of 1986, which has been gradually extended to many cities and counties in the province. First, the quality of rape and its nutritional value The quality of edible rapeseed oil is determined by the composition of fatty acids, its main ingredients are: oleic acid, linoleic acid, eicosanoic acid, linolenic acid, erucic acid and so on. Which erucic acid content, nutritional value will be reduced, high linolenic acid content easily rancidity, intolerance storage. Common rape, erucic acid content of 40 to 53%, linolenic acid content of about 10%, while the country
