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)
