Research on new technology for detection of rice milling degree

Abstract

Rice processing precision is an important index to evaluate rice quality. In this paper, a new technology for the detection of rice processing precision was studied. The rice samples were dyed by eosin y-methylene blue method, and then placed in the rice processing accuracy tester to determine the degree of leather retention, and then determine the rice processing accuracy level. Through the statistical analysis of the validation results among different laboratories, it was showed that the method has good repeatability, reproducibility, stability in line with the requirements of national standards, and meets the needs of quantitative detection of rice processing accuracy. The repeatability limit R and reproducibility limit r were calculated according to the inter laboratory validation data, and the method was standardized to guide the practical application.
