However,to our best knowledge,although most of thereports are concentrated on the effects of drying methods on musroom structures, little has been paid in the past to investigate the relationship beteeen musroom flavor compounds and drying methods. Therefore, the objective of this research was to study the changes of tasty compounds in P.eryngii, including soluble sugars and polyols,free ammio acids,5-nucleotides and organic acids, using different drying methods, such as hot air, vacuum, microwave, freeze and naturally air-drying. The findings of this work might provide theoreticalbasis for the manufacture of P.eryngii in order to enhance the commercial utilization of musrooms.
