谷物磷脂及其与谷物品质的关系研究进展

摘要

磷脂(Phospholipids,PLs)是一类重要的脂质.谷物中PLs含量虽少,但在谷物中起着关键的营养和理化功能,与诸多谷物品质特性的形成与维持密切相关.本文简要综述了目前谷物PLs的研究进展,重点介绍了水稻、玉米、小麦、大麦和燕麦等几种主要谷物中PLs及其脂肪酸的种类、构成与分布,阐述了PLs对谷物贮藏、加工与食用品质的影响,旨在为今后谷物品质改良及粮食贮藏提供新的思路.%Phospholipids (PLs)is a vital class of lipids. Although there is few content of PLs found in cereal grains, it plays funda-mental roles in grain nutrition, physicochemical properties and the formation and maintenance of cereal qualities. In the present re-view, we summarized the classification, composition and distribution of PLs and corresponding fatty acid in rice, maize, wheat, barley and oat. In addition,the effects of endogenous PLs on grain storage, processing and eating qualities have been discussed, for the pur-pose of providing new insight into the improvement of grain qualities and storage with manipulating PLs.
