RICE QUALITY AND PROCESSING A Comparison of Methods Used to Quantify Chalkiness of Head Rice
نویسنده
چکیده
Chalkiness of rice impacts functionality, visual perception, and marketability. A study was initiated to compare chalkiness scores resulting from the current, manual Federal Grain Inspection Service (FGIS) method and newer, semi-automated, digitalimaging systems. Chalkiness of head rice was determined for one mediumand two long-grain cultivar lots using the FGIS method and two digital-imaging methods. For the least-chalky lot, the digital-imaging methods predicted similar chalkiness values to those of the FGIS method. As surface chalkiness increased, the digital-imaging methods indicated increasingly greater chalkiness than did the FGIS method. However, alternative reporting formats show promise in reconciling chalkiness scores of digital-imaging methods with those of the manual FGIS method.

RICE QUALITY AND PROCESSING Differential Grain Development and Endosperm Gene Expression as Tools to Understand Rice Cultivar Responses to Increased Nighttime Air Temperatures
Mounting evidence has made it clear that increasing nighttime air temperatures contribute to decreased head rice yields and decreased grain quality due to chalkiness and altered physicochemical properties. Our goal is to determine some of the fundamental changes that occur in developing rice kernels as they respond to high air temperatures, especially at night. Panicles collected from field-gro...

متن کاملRICE QUALITY AND PROCESSING Impacts of Thickness Grading on Milling Yields of Long-Grain Rice
As variations in kernel uniformity can affect rice milling performance, limited thickness-grading to remove thin kernels was evaluated for effects on milling yields. Along with unfractioned (UNF) rice of four long-grain cultivars, rough rice was mechanically sieved, resulting in two thickness fractions, Thick (>0.079 inch) and Thin (<0.079 inch). Milled rice yield (MRY) and head rice yield (HRY...
