双低油菜是指商品菜籽中芥酸含量在5%以下,菜饼中的硫苷含量低于30微摩尔/克的油菜品种。发展双低油菜前景广阔。1.发展双低油菜可提高菜油的营养价值,改善人民生活,提高健康水平。传统菜油的显著特点是芥酸含量很高,一般为45%～50%。芥酸沸点高,凝固点也高,在人体内的消化率低,降低芥酸含量可以提高菜油的营养价值。另一方面,菜油中各种脂肪酸的比例具有相互消长的关系。油中芥酸含量降低以后,油酸和亚油酸含 Canola is the rapeseed cultivars that contain less than 5% erucic acid in their rapeseed meal and less than 30 μmol / g in their salads. Prospective development of double-low rape. 1. The development of double-low rapeseed can increase the nutritional value of vegetable oil, improve people’s lives and improve their health. The distinctive feature of traditional vegetable oil is high erucic acid, usually 45% to 50%. Erucic acid boiling point high freezing point is also high in the human body, low digestibility, reduce erucic acid can increase the nutritional value of vegetable oil. On the other hand, the ratio of various fatty acids in vegetable oils has a relationship of mutual depletion. After the erucic acid content of the oil is reduced, oleic acid and linoleic acid are contained
