Why is everyone talking about unpolished rice (brown rice) recently? Why are some of them red or even black? Read on to find out.
White rice* refers to rice which has its hull, bran and germ removed. Since the bran contains small amount of oil that can turn rancid, rice are polished to prolong its shelf life. However, this process also strips the rice of essential nutrients. And because
brown rice** has its bran and germ intact, it is considered as a
wholegrain and hence has a higher nutrition value.
*Polished rice will be known as white rice in the article.**Unpolished rice will be known as brown rice in the article.
There is a variety of
brown rice available in the market. The type and amount of colour pigments (anthocyanins) in the rice bran determines the colour of the rice. Similarly, the amount and type of aromatic compounds and fatty acids in different varieties of brown rice determines its unique flavour and aroma. Generally, brown rice has a nutty flavour and a chewy texture when cooked.
Brown Rice refers to rice that is unpolished where only the hull is removed. The health promoting and protective bran and fibre is retained in brown rice. Brown rice has a shelf life of six (6) months at room temperature.Red Rice contains a variety of anthocyanins that give its bran a red/maroon colour. Anthocyanin is an anti-oxidant that gives certain red-purple fruit and vegetables its colour. Red rice has a earthy and beany flavour. Red rice has a shelf life of about six (6) months at room temperature.Black Rice has a black coloured bran layer due to its unique anthocyanin combination and these anthocyanins cause black rice to turn into a deep purple colour when cooked. Anthocyanin is the same anti-oxidant that gives eggplants, and blueberries its deep purple.
In the past, black/purple rice was also known as forbidden rice because it was cultivated exclusively for Chinese emperors and forbidden to the Chinese commoners. Black rice has a shelf life of about six (6) months at room temperature.

On the other hand, medium and short grains tend to cling together and are more chewy and tender when cooked. Chose the type that best suits your preference.
