Several bioactive components are known to accumulate in rice during germination process. This study was to investigate the effect of germination process on γ-oryzanol levels in selected Sarawak local rice cultivars. Approach: Rice seeds were germinated for 4, 8, 12, 16, 18, 20 or 24 h at 25°C and samples were processed and analyzed for γ-oryzanol content. A partial extraction method was used for quantitative γ-oryzanol analysis. Results: Result showed γ-oryzanol concentrations in the rice cultivars varied from 0.099-0.340 mg g-1 on dry weight basis. Cultivars Udang Halus and Silah showed the highest concentration of γ-oryzanol after 16 h germination. Conclusion: The germination process exhibited diverse effects on the γ-oryzanol accumulation in rice and it was cultivar dependent.
