Non-Volatile Taste Components of Different Cultivated Mushrooms at Mycelia, Primordium, and Fruit Body Cultivation Stages

Abstract

Free amino acid, flavor 5’-nucleotides, organic acid, and the values of equivalent umami concentration of cultivable mushrooms, namely Pleurotus eryngii, Agrocybe aegerita, and Lentinus edodes, were investigated at different cultivation stages, mycelia, primordium, and fruit bodies. Fruit bodies were higher than mycelia in contents of total free amino acid, flavor 5’-nucleotides, and the values of equivalent umami concentration in three cultivated mushrooms, but lower in contents of total organic acid in P. eryngii and L. edodes, respectively. Contents of total organic acid at three cultivation stages of three cultivated mushrooms ranged from 32.65 to 125.50 mg g^–1 with the primordium stage of L. edodes being the highest. Overall, the amount of the nutrition and flavor components of mushroom might be related with mushroom species, fermentation way, and cultivated time. Some compounds could be also extracted from mycelia or primordium of mushrooms other than fruit body.
