摘要
采用电子鼻和气相色谱-离子迁移谱分析真空冷冻干燥、热风干燥、微波干燥处理后红花挥发性成分的组成及差异.电子鼻结果显示,W1W、W2W、W5S、W1S传感器在分析时发挥主要区分作用,且不同干燥方式处理的红花样品存在差异.气相色谱-离子迁移谱结果显示,不同干燥方式处理下的红花中共鉴定出57种挥发性成分(包括二聚体物质),包括21个醛类、9个酮类、9个酯类、6个醇类、5个烯类、4个含硫化合物、1个吡嗪类、1个酸类、1个呋喃类.经过指纹图谱进行差异性分析,真空冷冻干燥所得红花的挥发性成分种类更为丰富,总体含量更高,微波干燥法处理的红花产生了较多不良风味物质.因此,真空冷冻干燥是保留红花挥发性物质的最佳方式.
Abstract
Electronic nose and gas chromatography-ion migration spectrometry (GC-IMS) were used to analyze volatile components of safflower subjected to vacuum freeze-drying,hot air drying and microwave drying. The electronic nose results showed that W1W,W2W,W5S,and W1S sensors primarily distinguished the samples,revealing substantial differences among safflower samples processed by different drying methods. GC-IMS analysis identified a total of 57 volatile components (including dimers) in safflower under three different drying methods,including 21 aldehydes,9 ketones,9 esters,6 alcohols,5 alkenes,4 sulfur-containing compounds,1 pyrazine,1 acid and 1 furan. Differential analysis via fingerprint profiles revealed that volatile components from safflower subjected to vacuum freeze-drying were more abundant,and the overall content was the highest. Microwave drying treatment produced a relatively large amount of undesirable volatile compounds. Therefore,vacuum freeze-drying was determined to be the optimal method for preserving the volatile substances of safflower.
