It is known that black sticky rice with giant embryo (BSRGB, Milyang 263) and giant embryo rice (GER) contains higher levels of GABA than rice. Therefore, feeding BSRGB, GER, or rice freely to C57BL/6 mice with two-hour alcohol intake for 16 days was investigated. For two-hour alcohol intake, a repeated measure ANOVA (three treatment groups repeated across 16 days; 8 two-day blocks) yielded a significant group by block interaction (df=16, F=3.109, p=0.004). The independent t-test showed that significant suppression of two-hour alcohol intake was observed when subjects were administered with BSRGB, compared with the rice alone across all the two-day blocks (p<0.05). The paired t-test revealed that a significant suppression of two-hour alcohol intake was observed starting 4 to 16 days after freely feeding with BSRGB compared to before feeding. However, there is no significant difference in the two-hour alcohol intake observed between the before and after administration of rice. A repeated measure ANOVA revealed no significant group by block interaction for 22-hour water intake and body weight. However, a repeated measure ANOVA revealed a significant grouping by block interaction for food intake. These results indicate a change of two-hour alcohol intake is presumably caused by GABA, which is found in higher levels in BSRGB than in rice.
