检测项目

饱和脂肪酸含量测定：测定样品中不含双键的直链脂肪酸总量，用于评估样品的氧化稳定性和营养特性。

单不饱和脂肪酸含量测定：分析油酸等含有一个双键的脂肪酸比例，与样品的流动性和生理功能密切相关。

多不饱和脂肪酸含量测定：定量亚油酸、亚麻酸等含有两个及以上双键的脂肪酸，对评价营养价值至关重要。

顺反异构体分析：区分脂肪酸分子中双键的顺式与反式构型，反式脂肪酸的含量是食品安全的重要指标。

ω-3系列脂肪酸分析：专项检测α-亚麻酸、EPA、DHA等ω-3脂肪酸，评估其在保健食品和医药中的应用价值。

ω-6系列脂肪酸分析：定量亚油酸、花生四烯酸等ω-6脂肪酸，研究其与ω-3脂肪酸的比例关系。

短链脂肪酸分析：检测碳原子数小于等于6的挥发性脂肪酸，常见于发酵产物和肠道微生物代谢研究。

中长链脂肪酸分析：分析碳链长度为C8至C20的脂肪酸组成，是食用油和脂肪制品的主要检测内容。

游离脂肪酸含量测定：测定未与甘油酯化的游离态脂肪酸含量，反映油脂的新鲜度与水解程度。

脂肪酸甲酯化效率验证: 评估样品前处理中将脂肪酸转化为挥发性甲酯衍生物的转化率，确保后续质谱分析的准确性。

检测范围

食用植物油与动物脂肪: 包括大豆油、花生油、橄榄油、猪油、黄油等，分析其固有脂肪酸组成以鉴别品质和真实性。
