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