基于GC-IMS技术分析新疆不同品种核桃油挥发性成分的差异Differences of volatile components of different varieties of walnut oils in Xinjiang using gas chromatography-ion mobility spectrometry

为研究新疆主栽品种核桃油的挥发性成分差异，通过气相色谱-离子迁移谱（GC-IMS）技术对“温185”“新新2”“新早丰”“新萃丰”“扎343”“温81”6个品种低温压榨核桃油中的挥发性成分进行分析，并采用指纹图谱结合主成分分析（PCA）分析不同品种核桃油间挥发性成分的差异。结果显示，6个品种低温压榨核桃油样品中共检测到48种挥发性物质，其中包括醛类13种、醇类10种、酯类10种、酮类7种、烯烃类3种、酸类2种、醚类2种、杂环类1种。酯类是核桃油的主要挥发性成分，其中，乙酸乙酯（单体）相对含量最高，为10.61%~14.95%。指纹图谱结合PCA结果表明，不同品种核桃油挥发性成分存在差异，“新新...
