Rice is main food crops that all human consumes in all over the world, especially in Asia, regardless types of rice in each country they have. It is primarily classified according to its grain shape. There are various grain shape and specialty rice categories. Rice that has been harvested from the plant with its hull (husk) intact is known as rough or paddy rice. Sometimes, the hull is burned for use as an energy source since it is not eaten by humans. When the hull is removed from paddy rice it is known as brown rice. However, not all rice with the hull removed is brown in color. The bran and germ that gives brown rice its color can vary from light yellow to red to dark purplish black. Rice bran and germ contains greater amounts of dietary fiber, vitamins, minerals and other health-related components than the white center portion of the kernel (endosperm). But those outer portions of the kernel also contain more lipid (fats) material, making brown rice more susceptible to becoming rancid. It therefore has a shorter shelf life compared to milled white rice. Storage under cool conditions will lengthen its shelf life. Cooked brown rice is chewier in texture than its white rice counterpart and is described as having a slightly nutty flavor. Rice that has had its bran and hull layers removed by milling is called milled rice. White rice cooks faster than brown rice and has a longer shelf life. However, within the grain shape categories there are differences in qualities.
