Local residents who habitually consume cadmium-contaminated rice (Oryza sativa L.) can be exposed to cadmium toxicity in Mae Sot District, Tak Province, Thailand. This study aimed to investigate an alternative for utilizing cadmium-contaminated rice without compromising their health with hazard risks. First, cadmium (Cd) concentration in rice grain and crude rice oil was determined (0.203 ± 0.030 and 0.007 ± 0.002 mgCd/kg dry weight, respectively). Then crude rice oil extracted from cadmium-contaminated rice grain was studied for its anti-oxidative property using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging approach. Next, quantitative analysis of γ-oryzanol in crude rice oil was conducted. Results indicated that the level of cadmium concentration in the rice grain could cause adverse effects on human health. However, the amount of cadmium in the crude rice oil was safe for consumption. In crude rice oil anti-oxidative property, crude rice oil extracted from cadmium-contaminated rice was significantly higher than the control (P < 0.05). The concentration of γ-oryzanol in crude rice oil extracted from cadmium-contaminated rice was significantly higher than that in the control crude rice oil (P < 0.05). This study demonstrates an alternative way to use the rice grown in cadmium-contaminated areas for crude rice oil production for its anti-oxidative properties. 相似文献
