通过对4个水稻品种的直链淀粉含量、蛋白质含量、RVA特性及食味值的测定,研究了不同年份、异地栽培和不同贮藏时间对稻米主要品质性状的影响。结果表明:在不同种植年份,仅蛋白质含量在年度间差异显著;异地栽培的稻米其RVA特征值中除最终黏度外的其他4个指标及食味值表现出显著或极显著差异;稻米贮藏后,蛋白质含量和直链淀粉含量无明显变化,食味变劣,最高黏度和崩解值上升。
Through the determination of amylose content, protein content, RVA properties and taste value of four rice cultivars, the effects of different years, cultivation in different places and different storage time on the main quality traits of rice were studied. The results showed that only the protein content in different planting years was significantly different in the year. The RVA characteristic values of other cultivated rice showed significant or extremely significant differences in the four indexes except for the final viscosity, No significant changes in protein content and amylose content, deterioration of food, the highest viscosity and disintegration increased.
