Quality Properties of Oak Mushroom (Lentinus edodes) Based on Extraction Conditions and Enzyme Treatment

표고버섯(Lentinus edodes)의 추출조건 및 효소처리에 따른 품질 특성

  • Published : 2006.09.01

Abstract

The quality properties of oak mushroom were investigated using extraction conditions and enzyme treatments. The physiochemical properties were excellent at the extraction temperatures of $20^{\circ}C\;and\;40^{\circ}C$. The quality was increased as the extraction time increased but was best at the extraction time of 10 hr. The physiochemical properties such as soluble solid, reducing sugar and crude protein contents were best at the solvent ratio of 1:100 (w/v) so that it was set at 1:100. Thus, enzyme treatment was done at $50^{\circ}C$ for 2 hr with the solvent ratio of 1:100. The result showed that the best quality was shown using 0.2% protease and 0.2% cellulase. With the enzyme treatment, the essential amino acid contents increased by two folds but no difference was shown in $\beta-glucan$ content.

표고버섯의 추출 조건 및 효소 처리에 따른 품질 특성을 조사하였다. 추출온도에 따른 이화학적 특성은 $20^{\circ}C$$40^{\circ}C$일 때 우수한 것으로 나타났으나 추출은 시간이 증가함에 따라 품질특성이 높아지는 경향으로 전반적으로 10시간 추출이 우수한 것으로 나타났다. 추출 용매비의 경우 1:100(w/v)일 때 가용성 고형분 함량, 환원당 및 조단백 함량 등의 이화학적 특성이 가장 우수한 것으로 나타나 1:100으로 용매비를 설정하였다. 이상과 같이 설정된 $50^{\circ}C$, 2시간 및 용매비(1:100)의 조건으로 각각의 효소제를 처리하였다. 그 결과 protease 0.2% 및 cellulase 0.2% 구간이 품질특성이 가장 우수한 것으로 나타났다. 효소제 처리에 따라 필수 아미노산 함량은 2배 정도 증가하였으나 $\beta-glucan$ 함량은 차이가 크게 나타나지 않았다.
