World rice basically fall into two categories: Jing rice (Japonica rice) and rice (Indica rice), the difference in appearance is, Jing rice rounder a grain of rice, Indica rice longer. As regards quality, direct steel-of the Jing rice starch ratio is lower, more soft sticky rice; rice straight chain starch of high quality hard.
Variants of glutinous rice is rice, glutinous rice is Jing rice varieties, long is Indica glutinous rice varieties. Rice due to the composition of the starch refining and otherwise rice is different, direct steel-extremely low proportion of starch, therefore higher viscosity. And because of the starch granules have pits, refraction occurs when light through, causing rice white opaque, translucent with the General m different creature.
Just harvest of rice, because it contains water, fill the void of starch, therefore rendering transparent appearance, and rice is difficult to, respectively, after Sun Valley will become opaque.
Researcher at the COA agricultural improvement station in Taichung said Dr. Sheu Chih-Sheng, straight chain starch over 20% of rice, because of high hardness over Taiwan consumer acceptance. Currently nearly 85% Jing rice of rice, Indica rice and glutinous rice are mostly used for processing, rarely as the staple food rice.
If you compare the rice planting area in the world, will find that Jing rice than Indica minimal. The former originated in Japan, and Korea, and later extended to Northeast China and parts of the coastal area, Taiwan and the United States, such as California, which are grown in mainland China, Southeast Asia, South Asia, Africa, Latin America and other places.
Dr. Sheu Chih-Sheng pointed out that this difference in distribution due to the temperate Jing rice varieties on the one hand, poor heat resistance, Taiwan is already planted areas with the lowest latitude, on the tropical Asian residents are used to his fingers for food, so therefore you have Jing rice wouldn't like to high viscosity. Although Jing rice as the staple food of Chinese, the Government stationed in the South Pacific, Africa and Latin America mission, local extension of the uniform are rice, because of taking into account the climate and culture.
