ABSTRACT

This study examined that have excellent antioxidant effect and expand the base of consumption of lotus leaves. We added 1%, 3%, and 5% of lotus leaf powder to traditional gochujang. pH was the highest in the gochujang with lotus leaf powder 1%(p<0.001). The moisture was significantly lower as the addition of lotus leaf powder increased(p<0.01). The viscosity was the lowest with lotus leaf powder 5% was found to be 15.61 dPa·s(p<0.001). In chromaticity, the L value was the highest in the control, the viscosity of gochujang became darker and lessened(p<0.001). The a value and b value showed the highest in the control(p<0.001). The salinity was the lowest in the gochujang with lotus leaf powder 3%(p<0.001). The sugar content decreased as the more amount of lotus leaf. Total phenol and total flavonoid contents was the highest in the gochujang with lotus leaf powder 5%. The DPPH radical scavenging ability was higher as the more amount of lotus leaf. Reducing power and α-glucosidase inhibitory activity was the highest in the gochujang with lotus leaf powder 3%. The gochujang with lotus leaf powder can be expected to have higher antioxidant activities and to be a health functional food.
