초록

본 연구에서는 대부분 폐기 처분되어 활용되지 않는 유자씨의 활용도를 높이기 위하여, 냉압착 방법으로 추출한 유자씨 오일의 이화학적 특성, 멜라닌 생성 저해 및 항노화 효과에 관한 연구를 수행하였다. 유지에서 가장 중요하게 생각하는 부분인 산화안정성에서는 유자씨를 냉풍건조한 시료가 자연건조한 시료보다 thiobarbituric acid (TBA) 값이 약 30% 감소한 것으로 나타나 산화안정성이 다소 높은 것으로 확인되었다. 유자씨 오일은 주로 불포화지방산인 oleic acid와 linoleic acid로 이루어졌고 약 74% 함유하였다. 유자씨 오일과 유자씨 오일이 함유된 미스트의 미백 효과를 확인하기 위해 세포 내 tyrosinase 활성, 멜라닌 함량을 시험하였다. 그 결과 유자씨 오일의 함량이 증가할수록 tyrosinase 활성 및 멜라닌 함량이 감소하는 경향을 나타내었고 특히, 유자씨 오일이 5% 함유된 미스트 0.05%와 0.1% 처리 시 멜라닌 생성량은 각각 145.83%, 139.23%로 나타냈으며, 이는 MSH 군 대비 hydroquinone 50 µM 처리군의 멜라닌 억제능의 40% 수준에 해당하였다. 유자씨 오일을 함유한 유자미스트가 MMP-1 생성을 저해하고, pro-collagen 및 히알루론산 합성을 촉진하는 항주름 기능성 제품의 가능성을 시사하며 피부 미용 성분으로써 유자씨 오일의 활용에 대한 높은 가능성을 확인하였다.

In this study, in order to increase the utilization of yuzu (Citrus junos) seeds, which are mostly discarded and not utilized, the physicochemical properties, melanin production inhibition, and anti-aging effects of yuzu seed oil extracted by the cold pressing method. In terms of oxidation stability, which is the most important part of oil, the TBA value decreased by about 30% in the cold air drying yuzu seed sample compared to the naturally dried sample, indicating that the oxidation stability was somewhat higher. The yuzu seed oil mainly consisted of oleic acid and linoleic acid, which are unsaturated fatty acids, and contained about 74%. In order to confirm the whitening effect of the mist containing yuzu seed oil and yuzu seed oil, intracellular tyrosinase activity and melanin content were tested. As a result, the tyrosinase activity and melanin content tended to decrease as the yuzu seed oil content increased, and in particular, when treated with 0.05% and 0.1% yuzu seed oil, the melanin production was 145.83% and 139.23%, respectively, which was 40% of the melanin inhibitory capacity of the hydroquinone 50 µM treatment group compared to the MSH group. Yuza mist containing yuzu seed oil inhibits MMP-1 production, suggests the possibility of anti-wrinkle functional products that promote procollagen and hyaluronic acid synthesis, and confirms the high possibility of using yuzu seed oil as a skin care component.
