Effects of Drying Methods on the Physicochemical Aspects and Volatile Compounds of <i>Lyophyllum decastes</i>
In this study, fresh <i>Lyophyllum decastes</i> was dried using hot air drying (HAD), hot air combined with vacuum drying (HAVD), and vacuum freeze drying (VFD). Additionally, the quality and volatile compounds were analyzed. VFD achieved the best color retention, the highest rehydration...

| description | In this study, fresh <i>Lyophyllum decastes</i> was dried using hot air drying (HAD), hot air combined with vacuum drying (HAVD), and vacuum freeze drying (VFD). Additionally, the quality and volatile compounds were analyzed. VFD achieved the best color retention, the highest rehydration capacity, and the slightest damaged tissue structure; however, it recorded the longest drying time and the highest energy consumption. HAD was the most energy-efficient of the three methods. Furthermore, the products with more hardness and elasticity were obtained by HAD and HAVD—this finding was convenient for transportation. In addition, GC-IMS demonstrated that the flavor components had significantly changed after drying. A total of 57 volatile flavor compounds was identified, and the aldehyde, alcohol, and ketone compounds were the primary ingredient of the <i>L. decastes</i> flavor component, whereby the relative content of the HAD sample was apparently higher than HAVD and VFD. Taken together, VFD was better at preserving the color and shape of fresh <i>L. decastes</i>, but HAD was more appropriate for drying <i>L. decastes</i> because of the lower energy consumption, and was more economical. Meanwhile, HAD could be used to produce a more intense aroma. |
