Abstract

The antioxidant activities of the bread made from waxy black rice flour(WBRF) and wheat flour were investigated. The waxy black rice bread was manufactured with 10, 20, 30, or 40% waxy black rice flour(w/w). As the additive amount of WBRF were increased, DPPH(1,1-diphenyl-2-picryl-hydrazyl) radical scavenging activity and TEAC(trolox equivalent antioxidant capacity) were also increased. WBRF group showed the higher activity than the control group in DPPH radical scavenging activity and TEAC. The group with 10% WBRF added was not significantly different from the control group in metal chelating activity, but over 20% of addition, it had the higher metal chelating activity than that of the control group.
