Puffed rice and popped rice are types of puffed grain made from rice commonly eaten in the traditional cuisines of Southeast Asia, East Asia, and South Asia. It has also been produced commercially in the West since 1904 and is popular in breakfast cereals and other snack foods. Traditional methods to puff or pop rice include frying in oil or salt. Western commercial puffed rice is usually made by heating rice kernels under high pressure in the presence of steam, though the method of manufacture varies widely. They are either eaten as loose grains or made into puffed rice cakes. While the terms "puffed rice" and "popped rice" are used interchangeably, they are properly different processes. Puffed rice refers to pre-gelatinized rice grains (either by being parboiled, boiled, or soaked) that are puffed by the rapid expansion of steam upon cooking. Puffed rice retains the shape of the rice grain, but is much larger. Popped rice, on the other hand, refers to rice grains where the hull or the bran is intact. When cooked, the kernel explodes through the hard outer covering due to heating. Popped rice has an irregular shape similar to popcorn. There are various methods, both modern and traditional, for making puffed and popped rice.
