Brown rice is also called 'unpolished rice' and is brown in color. It is actually how all rice would look before it goes through the entire process of polishing. Every rice grain has an outer layer of a slightly stiff cover called the 'hull' or husk. The husk is always removed from the seed for both white and brown rice. Under this layer is a thin brownish layer called the 'bran' layer. This brownish layer on the rice seed clings to the seed and is removed through a polishing process. In the case of brown rice, the brownish bran layer is left intact and only the top stiff cover is removed. Brown rice is believed to be more nutritious as compared to white rice as, there are many nutrients in the brown layer that normally get taken off in the polishing process. When you cook brown rice, you would need to soak it in water for around 25 minutes to 30 minutes before doing the normal cooking process. If you thought that brown rice would be cheaper than white rice as it is only partially processed, you are wrong. You will find that in most shops and grocery stores, brown rice costs much more than white rice.
