| Abstract: | To explore the effect of hot air drying temperature on drying characteristics and volatile flavor compounds of Lyophyllum decastes, the applicability of eight common drying kinetic models to drying process was compared, and GC-IMS technology was used to detect the volatile flavor compounds under different drying temperatures. The results showed that hot-air drying of L. decastes was a typical falling rate drying, and the Midilli-Kucuk model could describe the hot-air drying process of L. decastes well (R2>0.99791, RMSE<0.0152, X2<2.31×10-4). Temperature had a significant effect on the volatile flavor compounds of L. decastes. A total of 47 volatile flavor compounds were identified under five drying temperatures, including 13 aldehydes, 8 ketones, 13 alcohols, 5 esters and 8 others. With the rise of drying temperature, the relative content of aldehydes decreased, while the content of alcohols, ketones and other substances (acetic acid, etc.) increased slightly. |
