Hence, it was thought that the rice flour was decontaminated by other effects.Įffects of milling on functional properties of rice flour.Ī commercial long-grain rice flour (CRF) and the flours made by using a pin mill and the Udy mill from the same batch of broken second-head white long-grain rice were evaluated for their particle size and functional properties. The temperature and pressure changes of the sample were not considered to have an effect on reducing the bacterial count during the milling. Although the brown and white rice grains were contaminated with approximately 10(6) and 10(5) CFU/g bacteria, the microbial load of the rice flour decreased as the mean particle diameter decreased, ultimately decreasing to approximately 104 and 103 CFU/g in the brown and white rice flour. In the jet mill, the particles are crushed and reduced in size by the mechanical impact caused by their collision. The decontamination effect of milling by a jet mill was investigated by counting the number of bacteria in brown and white rice flour with mean particle diameters of 3, 20, and 40Âµm prepared by the jet mill.
