| Abstract: | "BACKGROUND: Non-volatile and volatile flavor compounds of six Pleurotus mushrooms including Pleurotus citrinopileatus, P. cornucopiae, P. djamor, P. floridanus, P. ostreatus and P. sapidus were studied. RESULTS: The content of total free amino acids ranged from 21.80 to 40.60 g kg(-1) and the content of monosodium glutamate (MSG)-like amino acids ranged from 3.10 to 8.64 g kg(-1) . The content of total 5'-nucleotides ranged from 4.16 to 8.80 g kg(-1) while the content of flavor 5'-nucleotides ranged from 2.00 to 4.51 g kg(-1) . Sixty-three volatile compounds were identified in six Pleurotus mushrooms, including 17 aldehydes, 10 ketones, 14 alcohols, 2 ethers, 5 acids, 5 hydrocarbons, 10 heterocyclic and aromatic compounds. 1-Octen-3-one and 1-octen-3-ol were the key odor compounds in P. citrinopileatus, P. djamor, P. ostreatus, P. floridanus and P. sapidus, while 1-octen-3-one, 1-octen-3-ol and 2-octenal were the key odor compounds in P. cornucopiae. CONCLUSION: Pleurotus citrinopileatus had highest content of total free amino acids (40.60 g kg(-1) ), total 5'-nucleotides (8.80 g kg(-1) ) and flavor 5'-nucleotides (4.51 g kg(-1) ) than other Pleurotus mushrooms. Moreover, eight-carbon compounds were the most abundant compounds in six Pleurotus mushrooms. Our study should be helpful in promoting the cultivation and consumption of these Pleurotus mushrooms.
