Puffed grain

Puffed grains have been made for centuries with the simplest methods like popping popcorn. Modern puffed grains are often created using high temperature, pressure, or extrusion.

People eat puffed grains in many ways, but it can be as simple as puffed grain alone and with salt for taste. Commercial products such as Corn Flakes and Corn Pops mix many ingredients into a homogeneous batter. The batter is then formed into shapes then toasted and/or extruded. This causes them to rise, but not puff or pop. Puffed grains are very healthy if plain, but when other ingredients are mixed with them they lose some of their previous health benefits.
