Abstract

This study was conducted to investigate the proximate composition, free sugars, amino acids, and minerals in five Lentinula edodes cultivars collected in Korea. No significant differences in the content of crude fat and crude fiber were found between the samples; however, there was significant variation in the contents of nitrogen free extract, ash, and crude protein. Three kinds of free sugars (fucose, arabinose, and glucose) were identified by HPLC, with the glucose content ranging from 5.94% to 12.08%. Sixteen kinds of free amino acids were identified: the highest content of amino acids was found in 'Sanlim5ho' (13,768.33 mg%), while the highest content of free amino acids was found in 'Sanlim4ho' (6,790.57 mg%). The minerals detected in the L. edodes cultivars were potassium, calcium, magnesium, and sodium, the contents of which ranged from 567.16-2,356.09 mg%, 3.85-7.42 mg%, 9.79-20.88 mg%, and 19.60-22.62 mg%, respectively.

이 연구는 국내에서 개발된 표고의 성분차이에 의한 특성을 분석하고자 5 품종을 수집하여 일반성분 및 유리당, 아미노산 및 무기성분 함량을 비교하였다. 일반성분 분석 결과, 조지방과 조섬유 함량은 품종간에 큰 차이를 나타내지 않았으나, 가용성 무질소물, 회분, 조단백질 함량은 시료구별로 유의적인 차이가 나타났다. 유리당 함량을 분석한 결과 총 3종의 유리당이 검출되었으며, glucose 함량은 시료별로 5.94~12.08%까지 큰 차이를 보였다. 구성아미노산은 총 16종이 검출되었으며, '산림 5호'가 13,768.33 mg%로 가장 높게 나타났고, 유리아미노산은 총 16종이 검출되었으며, '산림 4호'의 총 유리아미노산 함량이 6,790.57 mg%로 가장 높게 나타났다. 무기성분 함량을 분석한 결과 potassium, calcium, magnesium 및 sodium 4개의 미네랄이 검출되었으며, sodium의 함량은 567.16~2,356.09 mg%를 차지하여 가장 큰 함량을 보였고, magnesium의 함량은 9.79~20.88 mg%였으며, calcium은 3.85~7.42 mg%로 나타났고, sodium은 19.60~22.62 mg%로 품종간 유의적인 차이가 나타나지 않았다.
