PROBLEM TO BE SOLVED: To provide a health food combined with sprouted brown rice and Bacillus natto, which can securely contribute to the maintenance and promotion of health.SOLUTION: After washing brown rice 1 in water containing Bacillus natto, the brown rice 1 is immersed in Bacillus natto water 4 containing Bacillus natto 3 kept at 15-20°C for 17-21 hours continuously to be sprouted. Then, the sprouted brown rice 6 with a bran layer eroded by the Bacillus natto is steamed in a steam pot with the pressure kept at 1.2 kg/cm3 for 5-7 minutes to be boiled. The boiled sprouted brown rice 6 is immediately cooled and vacuum-packed.COPYRIGHT: (C)2012,JPO&INPIT【課題】発芽玄米,納豆菌が組合わされて確実に健康の保持,増進に寄与する健康食品を提供する。【解決手段】玄米1を納豆菌が入れられた水で洗浄した後、玄米1を納豆菌3が入れられた納豆菌水4に15~20℃に維持して17~21時間継続して浸漬して発芽させ、発芽して糠層に納豆菌が浸食された発芽玄米6を蒸気釜で1.2Kg/cm3の圧力を維持して5~7分間蒸かすことにより炊飯する。発芽玄米6が炊飯された玄米飯を急速に冷却して真空パックする。【選択図】 図1
