Why do people wash rice?

Removing surface starch: Rice grains have a layer of starch on their surface which, if left unwashed, can make the cooked rice sticky and gummy. Washing the rice helps to remove this excess starch, resulting in fluffier and separate rice grains.

Removing impurities: Washing rice helps to remove any impurities or debris, such as dust, dirt, or small stones, that may be present. These impurities can affect the taste and texture of the cooked rice.

Reducing cooking time: Washing rice shortens the cooking time since the washed rice absorbs water more efficiently. Unwashed rice may require longer cooking time as some of the water is used to remove surface starch during cooking.

Improving flavor and texture: Some people believe that washing rice enhances the flavor and texture of the cooked rice. Washing helps to remove any off-flavors or odors from the rice and allows it to cook evenly.

Reducing arsenic levels: Certain types of rice, particularly brown rice, may contain higher levels of arsenic, a naturally occurring element that can be harmful to health. Washing rice can help to reduce arsenic levels by removing some of the arsenic present on the rice grains.

It's worth noting that the need for washing rice can vary depending on the type and quality of rice. Some pre-packaged rice may already be washed and ready for cooking. Always refer to the package instructions provided by the manufacturer to determine if the rice needs to be washed or not.
