摘　　要：为探究偏高水分粳稻谷低温储藏中的安全性和品质变化规律,在模拟低温环境(温度15℃)下对偏高水分粳稻谷(15.3%)储藏2.5年,监测了储藏期间稻谷霉菌数量、质量指标和储存指标的变化,并以常规水分(14.3%)的粳稻谷作对照进行了比较。结果表明,偏高水分粳稻谷在整个储藏期霉菌数量均低于105 cfu/g,未出现霉变现象。储藏期间,偏高水分和常规水分粳稻谷在质量指标和储存指标上的变化规律基本一致,但变化幅度略有差异。储藏结束时,偏高水分粳稻谷仍保持良好的品质,水分含量为14.2%,出糙率为80.2%,整精米率为66.8%,黄粒米含量为0.6%,脂肪酸值为23.2 mg/100 g,品尝评分值为77.2。In order to study the safety and quality change of high-moisture japonica rice stored at lowtemperature condition,the high-moisture japonica rice(moisture content 15.3%)was stored at simulated low-temperature condition(15℃)for 2.5 years.The changes of high-moisture japonica rice in mold contents,quality index and storage index during storage were monitored.Ordinary-moisture japonica rice(moisture content 14.3%)was used as control.The results showed that the mold content of highmoisture japonica rice was lower than 105 cfu/g during the whole storage period and there was no mildew phenomenon occurring to the rice.During storage,high-and ordinary-moisture japonica rice generally exhibited similar change trend in quality index and storage index,but there were some differences in change extents of the indexes.After the whole storage period,the high-moisture japonica rice retained excellent quality attributes:moisture content 14.2%,husked rice yield 80.2%,head rice yield 66.8%,yellow-colored rice content 0.6%,fat acidity 23.2 mg/100 g,taste assessing value 77.2.
