摘要

Problem to be solved: to provide a new method for estimating freshness of rice, a computer program for carrying out the method, and a freshness judgment apparatus provided with the computer program.The first freshness estimation value of rice is calculated by the absorbance measurement, and rice is analyzed by chromatography in the case where the first freshness estimation value is out of the range of the estimated freshness of the rice in the same age.Among the analyzed components, the value of the freshness of rice can be estimated by calculating the second freshness estimate value by comparing the analytical value of the preset component with the contrast data prepared by the pre measurement of a preset component.Diagram
