TREATMENT OF RICE BRAN WITH YEAST AND APPARATUS THEREFOR

摘要

PURPOSE:To prevent the oxidation of fat of rice bran and to obtain a high- quality rice bran having high nutrient value and suitable for feed by adding a specially treated yeast to bran and heat-treating the mixture. CONSTITUTION:A polysaccharide-assimilating yeast is added to the waste water generated by the water-washing of polished rice. The proliferated excess yeast and the remaining excess sludge are added to rice bran produced by the polishing of unpolished rice and heat-treated e.g. at 130 deg.C to obtain the objective rice bran. The ratio of the yeast and sludge to the bran is preferably adjusted to 10:1.
