基于GC-IMS技术分析湿提和热榨 油茶籽油风味的差异Flavor difference between wet extracted and hot-pressed oil-tea camellia seed oils based on GC-IMS

open access: yesZhongguo youzhi, 2023
为探究不同工艺对油茶籽油风味的影响,采用气相色谱-离子迁移谱(GC-IMS)技术对湿提和热榨油茶籽油风味物质进行分析。结果表明:湿提和热榨油茶籽油中均鉴定出32种风味物质;醛类是湿提和热榨油茶籽油主要的风味成分,其在湿提和热榨油茶籽油含量分别为62.62%和70.52%;湿提和热榨油茶籽油风味成分差异主要在于醛类和醇类物质含量,湿提油茶籽油的醇类和酯类物质含量高于热榨油茶籽油,糠醛含量(1.96%)远低于热榨茶籽油(11.18%);通过主成分分析和样品间相似度分析比较,两种工艺油茶籽油整体风味差异明显 ...
