How long the rice can not eat, there is no exact time, need to be based on the storage environment and temperature and other factors to elaborate. In winter, or relatively low temperatures, the rice storage time will be relatively long, the taste will not appear in the short term obvious changes, but will also breed relevant pathogenic microorganisms. If the rice is stored in a higher ambient temperature, or the surrounding environment, high humidity, mosquitoes, etc., then the rice deterioration time will be accelerated, may be two hours, the taste will change significantly. In summer, for the rice stored in the refrigerator, although the preservation time is extended, but the taste will be damaged, it is recommended to eat as much as do, to avoid waste. In daily life, if you find that the color, taste, smell of rice has changed, it is not recommended to continue to eat, so as not to cause diarrhea and other uncomfortable symptoms.
