Study on Sterilization Processes on Germinated Brown Rice

The sterilizing effects of distilled water,electrolyzed acid water,electrolyzed alkaline water and 1%(V/V)aqueous sodium hypochlorite on the germinated brown rice were stutied respectively in this paper,with Japonica rice Yu Ying 6 as raw material.The results indicated that the growth of microorganisms is inhibited by washing brown rice grains with electrolyzed acid water or aqueous solution of sodium hypochlorite,without adverse effects of rice germination.The growth of roots is also inhibited by the washing.Furthermore,the sterilization effect of electrolyzed acid water is slightly better than aqueous solution of 1%(V/V)sodium hypochlorite.The growth of both microorganisms and roots can be inhibited significantly by incubating rice grains in electrolyzed acid water and aqueous solution of sodium hypochlorite during the germination process,but poor germination is observed by the incubation.
