Abstract

Free amino acids in water-extracts and total amino acids in hydrolysates of three cultivated mushrooms, Agaricus bisporus, Pleurotus ostreatus and Lentinus edodes were analyzed by amino acid analyzer to know the compositional differences depending on species and portions (pileus and stipe). Eighteen amino acids were identified and quantified. The total nitrogen and protein nitrogen contents were in the range of 1.67-6.24% and 0.88-2.42% (dry basis), respectively. The considerable differences were often found among species and portions of mushrooms. All of them were found to be higher in the pileus part. The free amino acids conents in water-extracts were in the range of 10.04-37.85mg/g(dry weight) and the total amino acids contents in hydrolysates were in the range of 53.37-120.15mg/g(dry weight). Glutamic acid, serine, histidine, and alanine were dominent in the free amino acids pool and glutamic, aspartic acid, histidine, and alanine were in the total amino acids pool.

국내에서 널리 인공재배 되고 있는 식용버섯인 양송이 (Agaricus bisporus), 느타리(Pleurotus ostreatus) 및 표고버섯(Lentinus edodes)의 부위별 유리아미노산 및 전아미노산을 아미노산 자동분석기로 비교 검토하였다. 3종의 버섯에서 18종의 아미노산들을 확인 정량하였다. 이들이 함유한 총질소의 함량은 $1.67{\sim)6.42%$이었고 단백태질소는 $0.88{\sim}2.42%$의 범위로 종류 및 부위에 따라 큰 차이를 보였으며 이들 질소화합물들은 자루보다도 갓부위에 더 높게 분포하고 있었다. 유리아미노산의 분포범위는 $10.04{\sim}37.85mg/g(dry\;weight)$, 전아미노산의 범위는 $53.37{\sim}120.15mg/g(dry\;wieht)$로 나타났다. 유리아미노산중 가장 많이 분포하는 아미노산은 glutamic acid였으며 그 다음으로는 serine, histidine, alanine 순이었다. 전아미노산중 가장 많이 분포하는 아미노산은 glutamic acid이었으며, 그 다음으로는 aspartic acid, histidine, alanine순이었다.
