摘要
脂肪是稻米第3丰富的重要营养组分,是稻米“能量棒”,是水稻生命活动所需能量的重要来源之一。但稻米中粗脂肪含量较少且提取困难,前人对于稻米脂肪的研究多集中于稻米脂肪与品质的关系以及稻米脂肪酸组成成分上,关于稻米脂肪含量和组分调控的研究较少。本文综述了水稻籽粒脂肪的种类及分布、合成和分解代谢及其调控途径,以及稻米脂肪含量及其脂肪酸组分与稻米品质尤其是稻米蒸煮食味品质的紧密联系和影响因素,展望了提高和改善稻米脂肪含量及其组分的技术途径,以期为稻米脂肪与品质协同改良提供帮助。
Lipid is the third most important nutrient component of rice,it is the"energy bar"of rice and the main provider of energy for rice life activities.The crude lipid content in rice is low,and the extraction is difficult.The previous studies on rice lipid mainly focused on the relationship between rice lipid and quality and composition of fatty acids in rice.There were few studies on the regulation of rice lipid content and composition.This paper reviewed the types and distribution of rice grain lipid,their synthesis and catabolism and their regulatory pathways,as well as the close relationship between rice lipid content and fatty acid components and rice quality,especially the cooking and eating quality of rice,and their influencing factors.The technical approaches for improving the lipid content and components of rice were prospected to provide help for the cooperative improvement of lipid and quality.
