This is probably a habit of many people because of its convenience. However, the process of washing rice can cause tiny scratches on the non-stick surface of the pot. Over time, the non-stick surface will become increasingly damaged, leading to the failure of the non-stick layer.
Researchers have confirmed that when the non-stick surface of cooking utensils is damaged, the risk of toxic substances from the glue layer between the non-stick layer and the metal layer of the pot contaminating the food is very high, gradually causing the risk of cancer.
Therefore, wash rice in a basin or basket before putting them in the pot to cook, both to be safe and to protect the non-stick layer of the pot.
