In this study, the effective active ingredients of coffee waste extract and the caffeine content of coffee waste were confirmed using a high pressure hydrothermal extraction method to confirm the potential of coffee waste as a circular resource and a recycling material. In order to determine whether extraction of coffee waste affects caffeine reduction, ethanol content was soaked at room temperature for 48 hours at ratios of 0%, 30%, 50%, 70%, 100%, and then extract by high pressure hydrothermal extractor. As a result of quantitative analysis of caffeine on coffee waste using LC-MS, a caffeine reduction rate of 54.7% was confirmed in the coffee waste recovered after extraction with 70% ethanol hydrothermal extractor. Additionally, based on the results of a preliminary experiment that confirmed the highest caffeine reduction rate in high pressure hydrothermal extracted coffee waste with 70% ethanol content, in this experiment, extraction was repeated 3 times using coffee waste with 70% ethanol content in the same method as the preliminary experiment proceeded. Based on the results of a previous experiment that confirmed the highest caffeine reduction rate in hot water-extracted coffee waste with ethanol content of 70% in this experiment additional extraction was repeated three times using coffee waste with an ethanol content of 70% using the same method as the previous experiment. As a result of quantitative analysis of caffeine in coffee waste using LC-MS in this experiment, a high reduction rate of 98.7% of caffeine content was confirmed to be removed from coffee waste recovered by repeated extraction with 70% ethanol three times. The Korean Ministry of Food and Drug Safety confirmed that decaffeination, which removes 90% of the caffeine content, is possible with just two repeated experiments of coffee bean extraction. Therefore, it is expected that application to decaffeinated recycled products will be possible through repeated extraction of coffee grounds, which are discarded waste.

소개
인그리에(Ingrier)란 화장품 성분, 제형, 향, 칼라, 느낌 뿐만 아니라 유효성, 안전성 등을 감별하여 고객의 기호에 맞게 화장품을 추천하여 적합한 사용법을 제공해 고객의 만족을 이끌어 낼 수 있는 화장품 전문가를 말합니다. 본 한국인그리에학회는 대학, 기업 및 다양한 분야의 현장에서 화장품 산업의 발전을 기대하며 뷰티융합의 장을 열어보고자 합니다. 아울러 인그리에가 성장할 수 있는 각 분야의 우수한 연구를 확장하고 선도하는 수준 높은 학술지로서의 역할을 다하고자 합니다.
