| 摘 要： | 通过对初始水分为20.13%的稻谷进行间歇干燥试验,研究不同相对真空度以及不同干燥温度对稻谷干燥后品质的影响,测定干燥后稻谷爆腰率、脂肪酸值以及直链淀粉含量的变化,并对其进行相关性分析。试验结果表明:随着相对真空度的增加,稻谷的爆腰率小幅上升,脂肪酸值随之增加。随着干燥温度的增加,稻谷的爆腰增率、脂肪酸值以及直链淀粉含量也随之增加。相关性分析表明:稻谷的爆腰增率与脂肪酸值以及直链淀粉含量呈极显著正相关性,脂肪酸值与直链淀粉含量没有显著的相关性。

| Abstract: | The effects of relative vacuum and drying temperature on drying qualities of paddy with the initial moisture content of 20.13% were investigated by the intermittent drying tests. The fissuring rate, the fatty acid value and the amylose content were determined and their correlation analysis was conducted. The results showed that the fis- suring rates and the fatty acid value of paddy increased with the increase of relative vacuum. The fissuring rate, the fatty acid value and the amylose content increased with the drying temperature. The correlation analysis showed that the fissuring rate showed a highly significantly positive correlation with both of the fatty acid value and the amylose content. However, there was no significant correlation between the fatty acid value and the amylose con- tent. |
