摘要:

研究鼓风恒温干燥、真空恒温干燥和真空冷冻干燥这3 种干燥方式对香菇挥发性成分的影响,确定香菇的最佳干燥方式。以二氯甲烷为萃取溶剂,采用同时蒸馏萃取 (simultaneous distillation extraction,SDE)萃取香菇及其干制品的挥发性成分,使用气相色谱-质谱联用技术进行分析,结合主要挥发性成分的相对含量和权重值,对香菇干制品进行综合评分。结果表明,香菇及其干制品共被检出51 种挥发性化合物,采用真空恒温干燥制得的干制品的综合评分最高,为5.42,远远高于鼓风恒温干燥(1.02)和真空冷冻干燥(1.38)。

Abstract:

The effects of hot air drying, electro-temperature vacuum drying and vacuum freeze-drying on volatile compounds
in Lentinus edodes were investigated to find out the best drying process. The volatile compounds in Lentinus edodes and
its dry products were extracted by simultaneous distillation extraction (SDE) using dichloromethane as the extractant and
detected by gas chromatography-mass spectrometry (GC-MC). Comprehensive evaluations of dried Lentinus edodes were
conducted according to the relative contents and contributions of major volatile compounds. The results indicated that 51
compounds were detected and the product dried by electro-temperature vacuum drying showed the highest score of 5.42,
which was significantly higher than that of hot air drying (1.02) and vacuum freeze-drying (1.38).

Key words: drying process, Lentinus edodes, volatile compounds, simultaneous distillation extraction (SDE), gas chromatography-mass spectrometry (GC-MC)
