Abstract

이 발명은 녹차류를 클로로포름으로 1차 추출하여 녹차에 함유된 카페인을 제거하고 여과 잔사를 에틸아세테이트, 물 및 에타놀과 그 혼합물 중에서 선택한 용매로 2차 추출 여과하고 여액을 감압 농축하여 농축물을 얻는 방법에 관한 것임. 이 발명에 의하면 녹차류를 열수 추출한 다음 유기용매로 추출액중의 카페인을 추출제거하는 경우보다 폴리페놀 등 유효성분이 다량 함유되면서 카페인이 거의 없는 녹차류 농축물을 간단한 공정으로 얻을 수 있음. 농축물은 농축액 또는 분말상으로 얻어지며 식품 첨가제나 드링크제의 원액으로 사용됨.The present invention is a method of primary extraction of green teas with chloroform to remove caffeine contained in green tea, and the filtrate residue is extracted by secondary extraction with a solvent selected from ethyl acetate, water and ethanol and mixtures thereof, and the filtrate is concentrated under reduced pressure to obtain a concentrate. It is about. According to the present invention, green tea concentrates containing little amount of caffeine can be obtained by a simple process, since the green teas are extracted with hot water and then the caffeine in the extract is removed with an organic solvent. Concentrates are obtained in concentrate or powder form and are used as raw materials for food additives and drinks.
