The correlation between physicochemical property and the edibility quality of four high-quality rice varieties were studied. And the quality changes of the fresh wet instant rice made from four kinds of rice during storage were studied. At the same time, the effects of soaking time, soaking temperature and cooking temperature on the edibility quality of the instant rice were studied. The experimental results showed that the edibility quality of the instant rice was negatively correlated with amylose content, protein content, fat content and pos...
