Abstract

본 발명은 녹차잎으로부터 녹차 고유의 색, 향, 풍미 등을 손상없이 추출, 농축하며 제조된 농축액이 고품질의 상품성을 유지하는 방법에 관한 것으로 녹차잎에 50-80%의 알콜을 20-300분 처리한 후 적당량의 에리소르빈산(erythorbic acid)과 싸이클로덱스트린(cyclodextrin)을 녹인 탈이온수로 추출하고 평균입자경 0.1-1.0㎛ 필터로 미세여과 후 역삼투막을 이용하여 15-16°brix까지 농축하고 이 농축물에 탄네이스(tannase)를 0.005-0.05%로 처리하여 가스치환 용기에 저장함을 특징으로 하는 것이다.The present invention relates to a method of extracting and concentrating green tea's inherent color, aroma, and flavor without damaging the green tea leaves and maintaining the high quality commercially available concentrate. After treatment, extracted with deionized water dissolved with an appropriate amount of erythorbic acid and cyclodextrin, and after microfiltration with an average particle diameter of 0.1-1.0㎛ filter, concentrated to 15-16 ° brix using reverse osmosis membrane, and this concentrate It is characterized in that the tannery (Tannase) is treated with 0.005-0.05% and stored in a gas replacement container.

품질이 우수한 녹차 침출 농축물 및 그 제조방법Green tea leaching concentrate with excellent quality and manufacturing method

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

Claims (2)

녹차 본래의 색, 맛, 향기의 손실이 없고 농축 후 저장중에 침전물 형성을 방지하기 위해 먼저 원료 녹차잎에 50-80%의 알콜을 20-300분 처리하여 미생물 살균으로 초기 오염을 방지하고 지용성 비타민 등 녹차의 유효성분 용출을 유도한다.In order to prevent the formation of sediment during storage after concentration and without losing the original color, taste and aroma of green tea, 50-80% alcohol is first treated with 20-300 minutes of alcohol to prevent microbial sterilization to prevent initial contamination and fat-soluble vitamins. Induces the dissolution of active ingredients of green tea. 제1항에 있어서 전처리된 원료녹차잎에 적당량의 에리소르빈산(erythorbic acid)과 싸이클로덱스트린(cyclodextrin)이 용해된 탈이온수로 추출하고 여과 후 역삼투막을 이용하여 15-16°brix정도로 농축되었을 때 95% 주정을 가해 알콜 농도를 40-70%정도로 조성하여 10-60분간 유지하고 멸균수를 첨가하면서 계속 농축하여 20-25°brix까지 농축물을 제조한 다음 탄네이스(tannase)를 0.005-0.05%로 처리하여 가스치환 용기에 저장함을 특징으로 하는 녹차침출 농축물의 제조방법.The method of claim 1, extracted with deionized water in which an appropriate amount of erythorbic acid and cyclodextrin are dissolved in the pretreated raw green tea leaves, and filtered and concentrated to 15-16 ° brix using a reverse osmosis membrane. The alcohol is added to 40-70% alcohol concentration, maintained for 10-60 minutes, and concentrated continuously with the addition of sterile water to produce a concentrate up to 20-25 ° brix, and then the tanaceous to 0.005-0.05%. Process for producing a green tea leaching concentrate, characterized in that stored in the gas replacement container. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
