커피원두의 분쇄입도에 따른 커피 추출물의 이화학적 품질특성 및 휘발성 향기성분 분석

커피원두의 분쇄입도에 따른 커피 추출물의 이화학적 품질특성 및 휘발성 향기성분 분석 ABSTRACT In this study, we investigated the physicochemical properties of coffee brews according to coffee bean grinding grade. We also examined the effect of grinding grade on amounts of volatile flavor compounds. Coffee brew samples were separated using standard sieves (with pore sizes of 850, 600, and 425 μm), making particle sizes of ground bean..
