Biochemically assisted rice whitening for improving head rice yield

The maximum attainable head rice yield in conventional long grain milling is approximately 64%, with around 15% being lost as a result of broken kernels. primary objective this project was, therefore, to improve the yield. To achieve goal, biochemically assisted whitening processes involving application different aqueous solutions were evaluated. Head was increased for all tested liquids (3.3–3.8% depending on liquid) Gladio-type brown treated 0.5% liquid prior 40 Kett using lab-scale horizontal friction-type McGill whitener. However, moistening led caking chamber. In comparative trials, use containing enzymes, sorbit, or sodium chloride instead pure water delivered slightly, but nevertheless, significantly higher degree whiteness directly after while it did not significant reduction number Since average has 43% commercial value than kernels, 3.6% improvement achieved by adding would an estimated increase profit 7.5 t/h mill 0.83%.
