【摘要】 通过GC-MS分析10种不同品牌的转基因大豆油和传统普通大豆油中的脂肪酸结构组成,评价基因改性对大豆油脂肪酸营养成分的影响,为人们在转基因的选择上提供依据。结果表明大豆油中富含不饱和脂肪酸,相对含量最高的是多不饱和脂肪酸C18:2,高达60%。转基因大豆油中的脂肪酸含量与传统普通大豆油无显著性差异。脂肪酸成分的聚类分析显示,10种大豆油交织在一起,无分类现象。研究结果表明,转基因大豆油中的脂肪酸与传统普通大豆油实质等同,食用转基因大豆油能够提供等同的饱和脂肪酸营养成分。更多还原

【Abstract】 The composition of fatty acids in 10 different kinds of brand’s soybean oil were analyzed by GC-MS. The results showed that soybean oils were abundant with unsaturated fatty acids. The highest content in soybean oils was fatty acid C18:2, which was as high as 60%. There were no significant differences on the contents of fatty acids between transgenic soybean oils and conventional soybean oils. Hierarchical clustering analysis(HCA) of fatty acids in soybean oils showed that all soybean oils were intersect together, not clearly cluster as transgenic soybean oils and conventional soybean oils. The research indicated that fatty acids in transgenic soybean oils were substantially equivalent with those in conventional soybean oils, which could provide equivalent nutrient of fatty acids for people.更多还原
