Twenty species of rice were selected as sample. The main effects of physical-chemical characteris-tics, cooking quality and flavor on eating quality of rice were investigated. Eating quality of rice were estimated by sensory evaluation, correlation analysis results showed that:water, protein and fat content of japonica rice had significant effects on eating quality, and the protein content was negatively correlated with eating quality (p≤0.01);water, appearance and cold cooked rice texture of indica rice had significant positive effects on the eating quality(p≤0.05) , but the protein was negatively correlated with eating quality(p≤0.01). In cooking characteristics, rate of water absorption and expansion for japonica rice were negatively correlated with gloss and viscoelasticity of the cooked rice (p≤0.05);on the other hand, expansion rate of indica rice were posi-tively correlated with gloss, and cold texture of cooked rice (p≤0.05);moreover, dry material and iodine blue value of japonica rice had positively correlation with eating quality(p≤0.05), iodine blue value of indica rice had negatively correlation with softness(p≤0.05).%选取粳米、籼米共20种,测定大米的化学特性、蒸煮特性、食味值等对食味品质有主要影响的因素,通过感官评价对米饭的口感品质进行测定,经相关性分析结果表明:粳米的水分、蛋白质、脂肪对食味品质均有显著影响,其中蛋白质与食味品质呈极显著负相关(p≤0.01);而籼米水分与米饭外观、冷饭质地呈显著正相关(p≤0.05),其中蛋白质与食味品质呈极显著负相关(p≤0.01).蒸煮特性中,粳米的吸水率、膨胀率对米饭的光泽、黏弹性影响显著,均呈显著负相关(p≤0.05),而籼米的膨胀率与米饭光泽、冷饭质地呈显著正相关(p≤0.05);粳米的干物质、碘蓝值与食味品质呈显著正相关(p≤0.05),而籼米的碘蓝值与软硬度呈显著负相关(p≤0.05).
