In order to improve the moisture content of high-quality rice storage before storage, high-quality rice with different water gradients (11.5%, 12.5%, 13.5%, 14.5%, 15.5%, and 16.5%) was placed in 15 ℃ and 20 ℃ for simulated storage. The processing quality changes such as roughness, whole milled rice rate, yellow rice, chalky grain rate, rice gelatinization characteristics and rice taste score were studied during storage. The results showed that the moisture content could be better in range 13.5%~14.5%, and the whole milled rice rate was bette...
