Background : Hippophae rhamnoides L. are known for antioxidant, immunodeficiency, skin protection, influenza infection and prevention of heart disease. This study was carried out to confirm the possibility of functional food by changing the antioxidant effect using H. rhamnoides L. leaf extracts to the Gamju (sweet rice drink).
Methods and Results : A total of 12 samples were made of different processes. Briefly, the H. rhamnoides L. leaf were extracted at 60℃ in two different conditions (EtOH 100%, water 100%). Gamju was fermented into three different koji (Aspergillus oryzae – red, yellow, black). In addition, The addition of H. rhamnoides L. leaf extracts were mixed in two ways (simultaneous saccharification, mixed after saccharification). Antioxidant activities were estimated by 2,2-diphenyl-1-picryl-hydrazil (DPPH) and reducing power assay. Total phenolic content (TPC) was determined by Folin-Ciocalteu method. In this study, we found that Gamju mixed with H. rhamnoides L. leaf increased antioxidant effects and TPC than the control (original Gamju). Moreover, the anti-oxidant effects of the mixed H. rhamnoides L. leaf with Gamju after saccharification exhibited more activity than simultaneous saccharification in DPPH assay.
Conclusion : These results demonstrated that samples of added to the H. rhamnoides L. leaf could be use as functional food.
