在5℃、20℃、30℃、40℃四种储藏温度下和调质保湿密封恒温与自然通风恒温两种储藏状态的环境条件下,分别对水分为13.0%、14.0%、15.0%左右(±0.1%)的“鄂香1号”、“二优培九”、“汕优63”三个不同优劣品种的籼稻谷进行为期2个月的实验室模拟储藏试验,每间隔10天对其脂肪酸值、粘度、发芽率等进行测定,实验结果表明:稻谷品种越优,含水量越大,储藏温度越高,其储藏品质劣变率和劣变速率越大。相比而言,稻谷含水量在14.0%以下,储藏环境温度在20℃以下,品质下降变化较小。
Under the environmental conditions of 5 ℃, 20 ℃, 30 ℃, 40 ℃ storage temperature and the two conditions of sealed moisture and sealed natural temperature and natural temperature, respectively, the water content was 13.0%, 14.0% and 15.0% ± 0.1%) of “Hubei Hong 1”, “Youyoupeijiu”, “Shanyou 63” three different advantages and disadvantages of indica rice for 2 months in the laboratory simulated storage test, every 10 days Its fatty acid value, viscosity and germination rate were measured. The experimental results showed that the better the rice varieties, the higher the water content, the higher the storage temperature, the worse the quality deterioration and deterioration rate of the storage quality. In contrast, rice moisture content below 14.0%, storage temperature below 20 ℃, the change in quality is smaller.
