초록

국내외에서 수집한 표고 품종을 대상으로 영양성분 및 ${\beta}$-glucan 함량을 분석한 결과 수집한 표고의 유리당 함량을 분석한 결과 총 4종의 유리당이 검출되었으며, 그 중 trehalose 함량은 시료별로 0.83~9%까지 큰 차이를 보였다. 구성아미노산 함량을 분석한 결과 총 아미노산함량은 중국 톱밥배지 표고 JMI10050에서 17,672 mg%로 가장 높게 나타났으며, 필수아미노산의 함량은 국내 원목재배표고 JMI10059에서 6,211 mg% 가장 높게 나타났다. 유리아미노산 함량을 분석한 결과, 총 16종의 아미노산이 검출되었으며, 주요 유리아미노산으로는 histidine, glutamic acid 및 arginine으로 나타났다. 필수 유리아미노산인 threonine, valine, methionine, isoleucine, leucine, phenylalanine, histidine 및 lysine의 함량은 중국 톱밥배지 표고 JMI10052에서 521.06 mg%로 가장 높게 나타났다. 중국에서 수집한 표고에 비하여 국내에서 재배된 표고의 ${\beta}$-glucan이 약 10% 가량 높게 검출되었고, 그 중 국내원목재배 표고 JMI10066이 31.74%로 가장 높은 함량을 나타냈다.
