Abstract
In this study, the proximate composition, free amino acids content and 5â²-nucleotides in frozen, canned and salted Agaricus bisporus (A. bisporus) were investigated. We found that the three kinds of A. bisporus products were good sources of protein, with amount varying in the ranges of 16.54-24.35Â g/100Â g (dry weight). Freezing, canning and salting process, followed by 6Â months of storage led to a significant reduction in free amino acids, especially tyrosine, alanine, glutamine and cysteine. There were medium levels of MSG-like amino acids in frozen A. bisporus and canned A. bisporus, and low levels of MSG-like amino acids in salted A. bisporus. The mount of flavor 5â²-nucleotides in frozen A. bisporus was higher than that of canned and salted A. bisporus. The present study thus suggests that freezing is beneficial for the preservation of A. bisporus.
