3.2. Bioactive Compounds
Rice Formula 2 (before cooking) contained all levels of γ-oryzanol, α-tocopherol and phenolic substances of 42.91 mg/100g, 0.30 μg/ml and 0.85 mg GAE/g, respectively, which were higher than 29.15 mg/100g, 0.24 μg/ml and 0.43 mg GAE/g for Rice Formula 2 (after cooking), respectively (Table 2). When Rice Formula 2 was compared (before and after cooking), all levels of γ-oryzanol, α-tocopherol and phenolic substances were found to be different with statistical significance (p0.05), possibly because cooking rice at mildly reduced α-tocopherol levels leaves fewer benefits to be gained from significant substances in rice grains.
