菜籽多酚的抗营养作用机理及减量措施

Action Mechanism of Antinutrition and Reducing Measures of Polyphenol from Rapeseeds

油菜籽是世界第三大油料,也是我国食用植物油的主要来源和潜在的饲用蛋白源。油菜籽加工过程中,大部分的菜籽多酚留在副产品菜籽粕中,使其合理利用受到制约,尤其作为动物饲料时,不仅其色泽深黑不受欢迎,而且其辛辣味和涩味严重影响动物的适口性,降低动物对营养物质的消化和吸收,对动物体有毒性作用。研究综述了菜籽多酚的组成、结构、抗营养作用机理和减量处理措施,以期为提高菜籽粕利用价值,开发优质蛋白资源提供参考。

Rapeseed is the third oil crop in the world and is not only the main source of edible vegetable oils in China,but also the potential source of feed proteins.Polyphenol from rapeseeds mostly remains in rapeseed meal and the byproduct of rapeseed oil processing,which restricts the utilization of rapeseed meal.In particular,when being used as animal feed,it is not welcomed due to the black color.More,it is pungent and astringent and seriously affects the animals to digest and absorb nutritive materials and is noxious to animal bodies.In this paper,the components,structures,antinutrition mechanism and reducing measures of polyphenol from rapeseeds were summarized so as to provide reference for improving the value of rapeseed meal and developing a high-quality protein resource.
