毛细管气相色谱法检测方便面中棕榈油主要脂肪酸含量

Determination of major fatty acids in palm oil in instant noodle by using capillary gas chromatography

方便面经酸水解后用乙醚提取，其中脂肪酸用ＫＯＨ一甲醇快速甲脂化，用毛细管气相色谱法测定。

After instant noodles were hydrolyzed by acid,then fatty acid in palm oil of instant noodle were extracted with ether.Fatty acid was derived as methyl esters using KOH\|CH\-3OH solution and determined by GC.The area normalization method was used to determine the distribution.Instant noodle samples obtained from one mamufacturer were analyzed to investigate the cause of abnormal flavor.
