Parboiling is a hydrothermal process in which the crystalline form of starch present in the paddy rice (the rice grain from the field) is changed into an amorphous one as a result of the irreversible swelling and fusion of starch. This is accomplished by soaking, steaming, drying, and milling the rice. The parboiling process produces physical, chemical, and organoleptic modifications in the rice, with economic and nutritional advantages
