With a little help from USDA, consumer-grade photo scanners could revolutionize rice grading.
Consumers much prefer whole kernels of milled rice over broken pieces. Whole kernels offer more consistent cooking qualities and are in many cases considered more visually appealing. As a result, the price paid to a rice producer for a load of rough rice can be impacted by the percentage of broken kernels within a sample of rice after it has been milled.
USDA’s Grain Inspection, Packers and Stockyards Administration is developing software for use with consumer-grade photo scanners to measure the percent of broken kernels in milled rice quickly and accurately. When rough rice is graded in accordance with USDA’s Rice Grading Standards, the percentage of broken kernels within a sample is determined by a trained grader’s visual inspection.
