The present study aimed to investigate the biological activities and nutritional contents of extracts from three types of edible mushrooms (Pleurotus ostreatus, P. eryngii, and Hericium erinaceus) following different roasting treatments. Roasting by a household multi-oven (HR60) decreased the total polyphenol contents, as well as DPPH radical scavenging and nitrite scavenging activities compared with the fresh samples, and no significant difference was observed between the different roasting times. As a result of rotary drum roasting (CR) treatment, we could observe a decrease in the DPPH radical scavenging activity in all roasted mushroom samples compared with the fresh samples, whereas nitrite scavenging activity increased in roasted P. eryngii and H. erinaceus. Additionally, total polyphenol contents increased significantly in roasted H. erinaceus. In each roasted sample dried by HR60 and CR, the amount of palatable-taste amino acids (e.g., glutamic acid) and sweet-taste amino acids, including glycine, serine, alanine, and threonine, increased in P. ostreatus, whereas the amount of bitter amino acids , including leucine, isoleucine, histidine, valine, and methionine, decreased compared with the fresh samples. In P. eryngii and H. erinaceus samples, we also observed an increase in the amount of palatable and sweet-taste amino acids upon the roasting treatments; however, the amount of bitter amino acids increased simultaneously following the roasting treatments. These results suggest that CR treatment is more effective in increasing the biological activities and nutritional contents, such as palatable and sweet-taste amino acids, compared with HR60 treatment.
