亚洲种植的大米,根据品种主要分为粳米、籼米两类。大米的主成分是淀粉,有直链与支链两种不同结构,这两种淀粉的不同比例影响了米饭的黏性和口感,例如,籼米的直链淀粉较多,口感较硬,而粳米的支链淀粉较多,黏度较高。
The Asian cultivated rice, the rice, indica rice varieties are divided into two categories. The main component of the rice starch, amylose and amylopectin have two kinds of different structure, different proportions of these two kinds of starch affected the Steamed Rice stickiness and taste, for example, amylose of rice, the taste is hard, and the rice amylopectin is more, high viscosity.
大米在收成后仍具有生命力(酵素活性),其品质在储存期间会逐渐衰变。所以,就有所谓的新米和旧米之分。由于储存期间会有油脂氧化的问题,所以新米的口感和香味一般都比旧米好。而且,旧米的色泽较黄,透明度也较差。
Rice still has vitality in post harvest (enzyme activity), its quality will gradually decay during storage. Therefore, there is the so-called new meters and meters of the old. The lipid oxidation during storage will have problems, so the new rice taste and smell are generally better than the old meters. Moreover, the old meters of color is yellow, the transparency is poor.
若要保留新米的口感和品质,可将大米储存在低温环境中,比如保存在冰箱中就是比较好的方法,可以降低大米油脂氧化和米虫的滋生。醉仙鸭http://www.zuixianya666.com/
If you want to keep the taste and quality of new rice, rice can be stored in low temperature environment, such as stored in the refrigerator is a better method, can reduce the fat oxidation and even the breeding of rice.
但要注意,大米放进冰箱后就不能再拿出来常温存放了。因为,温度变化会令大米表面吸附水分,变得潮湿易变质。而且,厨房的温度相对较高,家里不要一次囤积太多大米,也可避免旧米味道变差。
But it should be noted that, after the rice in the refrigerator can not be out of storage at room temperature. Because of the temperature change, will make the rice surface water adsorption, become moist easy metamorphism. Moreover, the kitchen temperature is relatively high, the house not a hoard too much rice, also can avoid the old rice taste variation.
