GC-TOF-MS定性和定量评估5种木本油料种籽油的脂肪酸（英文）

论文摘要

采用气相色谱-飞行时间串联质谱和超临界二氧化碳提取技术,分析评价5种木本油料种籽油的脂肪酸组成及相对含量。油茶和榛子种籽油中富含油酸,亚油酸是沙棘和文冠果种籽油中的主要脂肪酸,牡丹种籽油中的亚麻酸含量最高。沙棘种籽油的单不饱和脂肪酸与饱和脂肪酸比值为1.57:1,亚油酸与亚麻酸的比值为1.56:1,符合功能性健康食用油的标准;牡丹种籽油是补充人体ω-3脂肪酸的优质食用油;油茶和榛子种籽富含单不饱和脂肪酸,适合食品加工;文冠果种籽油含有3种长链单不饱和脂肪酸（如神经酸等）。本实验评价了5种木本油料油脂脂肪酸的组分,对指导企业生产生物活性油和人们的健康消费具有重要意义。
