Aloe has been widely used as a cosmetic and medicinal plant. Until now, several effects such as antioxidant, anti-cancer, anti-diabetic, immunity and whitening of aloe gel extract have been reported, but research on aloe by-products occurring in food processing has not been actively conducted. In this study, we investigated whether the aloe by-product extract from food processing could be used as a functional biomaterial. Cytotoxicity was not seen in both the mixer and press extracts. Inhibition of 3T3-L1 adipocyte differentiation was detected only in the mixer extract and not in the press. It was confirmed that hyaluronic acid accumulation and tyrosinase inhibition increased according to the treatment concentration of the mixer extract. The antimicrobial activity of the mixer extract was observed in the Porphyromonas gingivalis strain, but not in the Streptococcus mutans strain. Antioxidant activity through DPPH and SOD analysis increased with the concentration of the mixer extract. In summary, it was confirmed that the mixer extract of aloe by-products has the effect of inhibiting adipocyte differentiation, moisturizing, whitening, and antioxidant, suggesting the possibility of using it as a functional bio-material for health drinks or beauty masks.

알로에는 화장품 및 약용 식물로 널리 사용되고 있는 식물로서 알로에 젤 추출물에서 항산화, 항암, 항 당뇨, 면역, 미백 등 여러 효과가 보고되었지만, 알로에 가공에서 발생하는 부산물을 이용한 연구는 많이 수행되지 않았다. 본 연구에서는 알로에 가공 과정에서 나온 부산물을 이용한 추출물이 기능성 바이오 소재로 활용될 수 있는지를 조사하였다. 먼저 믹서 추출물과 착즙 추출물 모두에서 세포 독성은 보이지 않았다. 3T3-L1 지방 세포 분화의 억제는 믹서 추출물에서만 확인되었다. 믹서 추출물의 처리 농도에 따라 히알루론산 축적 및 Tyrosinase억제가 증가하는 것을 확인하였다. 믹서 추출물의 항균 활성은 Porphyromonas gingivalis 균주에서 관찰되었지만, Streptococcus mutans 균주에서는 관찰되지 않았다. DPPH 및 SOD 분석을 통한 항산화 활성은 믹서 추출물의 농도에 따라 증가하였다. 본 연구를 통해 알로에 부산물의 믹서 추출물은 지방 세포 분화억제와 보습, 미백, 항산화 효과가 있음을 확인하였으며, 건강 음료나 미용 마스크 등의 기능성 바이오 소재로 활용이 가능한 것을 시사하고 있다.
