基于气相色谱-离子迁移谱法分析不同种类功能性油脂中挥发性成分
Analysis of volatile components in different types of functional lipids using gas chromatography-ion mobility spectrometry
摘要
Abstract
Gas chromatography-ion mobility spectrometry(GC-IMS)was employed to comparatively analyze the differences in volatile components in seven types of functional lipids:rapeseed oil,peony seed oil,walnut oil,sesame oil,shiny-leaved yellowhorn oil,perilla oil,olive oil.A total of 46 volatile components were identified in the seven functional lipids(counting monomers,dimers,and trimers only once),including 10 aldehydes,9 esters,8 alcohols,7 ketones,5 acids,2 alkenes,and 5 heterocycles.A volatile component fingerprint was established for each lipid to identify their characteristic volatiles.There were significant differences in both types and relative contents of volatile components among the seven functional lipids.Characteristic component fingerprinting and principal component analysis(PCA)spectra were used to effectively distinguish these functional lipids based on these differences in volatile components.关键词
