Abstract
The effect of germination on the antioxidant capacity of pigmented and non-pigmented rice was investigated. The blackish purple Superjami, reddish-brown Superhongmi, and ordinary non-pigmented brown rice were germinated for 72 h. The germinated rice grains were extracted with 80% methanol and their antioxidant activities and compounds were analyzed. Germination substantially increased the free radical scavenging activity, reducing power, ferrous chelating ability, and superoxide dismutase activity in all the rice samples. The anthocyanin, tannin, phenolic, phytic acid, tocopherol, and tocotrienol contents were markedly higher in germinated rice compared to those of the non-germinated ones. The pigmented varieties exhibited greater antioxidant capacity and higher amounts of antioxidant compounds than the non-pigmented brown rice in both germinated and non-germinated forms. Superjami showed higher antioxidant activities and anthocyanin, phenolic, tocopherol, and tocotrienol contents than Superhongmi. These findings illustrate that germination could increase the antioxidant compounds and enhance the antioxidant capacity of pigmented rice which may be useful as functional foods.
