晾晒方法对粳稻稻米物理品质的影响

不同地区的晾晒方式不同,为了探求晾晒方法对粳稻稻米品质造成的影响,采用六种不同的方法对田间成熟的粳稻稻谷进行晾晒处理。结果表明,晾晒温度是影响稻米碾米品质和外观品质的重要原因,高温晾晒环境使整精米率下降,垩白度增加。在晾晒过程中要注意温度不能太高,最好的办法就是置于通风,空气湿度较小的遮荫处晾干。

Effects of Air- drying Methods on Physical Quality of Japorica Rice

Air-drying methods vary in different districts.Effects of six different trentments of air-drying on relative physical quality of japorica rice at maturity was stutied.The results indicated that the temperature was an important fator to effect milling and appearance quality of rice.The percentage of head milled rice was descended with high temperature,but the percentage of chalky rice was increased.The temperature of air-drying methods was not too high.The best way of air-drying methods was to dry in the ventilation and low humidity condition.
