However, to our best knowledge, although most of the reports are concentrated on the effects of drying methods on mushroom structures, little attention has been paid in the past to investigate the relationship between mushroom flavour compounds and dry- ing methods. Therefore, the objective of this research was to study the changes of tasty compounds in P. eryngii, including soluble sug- ars and polyols, free amino acids, 50-nucleotides and organic acids, using different drying methods, such as hot air, vacuum, micro- wave, freeze and naturally air-drying. The findings of this work might provide theoretical basis for the manufacture of P. eryngii in order to enhance the commercial utilization of mushrooms.
