초록
밤나무 잎을 이용해 제조한 불발효 처리한 증제차와 반발효차의 항산화 및 항미생물 효과를 탐색하였다. 각각의 밤잎차 물추출물을 동결건조한 시료를 DPPH-radical scavenging activity를 측정하여 항산화 효과를 검토한 결과, 두 종류의 차 모두 대조구로 사용한 BHT보다 동일농도에서 강한 활성이 나타났으며, 이들의
Antioxidative and antimicrobial effects of the extracts of Castanea crenata leaf tea, steamed tea and semi-fermented tea were investigated.
