摘　　要：植物油脂是人们膳食的主要成份，占人体膳食总供热能的２５％以上。营养科学研究表明，膳食脂肪的含量及组成与人体健康紧密相关。目前，人们很难采用常规的育种手段控制油脂的组成。然而，先进的基因工程技术为获得能满足食品功能和人体营养两方面需要的植物脂质提供了可能，本文介绍了近年来利用基因工程技术改造植物脂质已取得的一些进展。Vegetable oil is a major component of human diet comprising as much as 25% of average caloric intake. Until recently, it was not possible to exert significan control over the chemical composition of vegetable oil derived from different plants. However the advanced genetic engineering has provided opportunities to tailor the composition of plan-derived lipid so tha they are optimized with respect to food function and hurnan dietary needs. This review discusses the progress of using biotechnology in modifying plant lipids.
