Method for determining moisture content of rice to be cooked, immersion time determination device, and rice cooking equipment

摘要

PROBLEM TO BE SOLVED: To easily and surely evaluate a moisture state of rice to be immersed to water, and preferably control texture of rice after being cooked.SOLUTION: The rice to be cooked which is disposed in a state of being immersed to water, is optically monitored, for measuring moisture content-related information which relates to a moisture content of the rice to be cooked, chronologically, then, a saturation state of the moisture content of the rice to be cooked which is estimated based on the moisture content-related information is detected, for determining that the rice to be cooked is in a moisture state suitable for rice cooking.SELECTED DRAWING: Figure 1
