What is the main ingredient used in puffed corn snacks?
The main ingredient used in puffed corn snacks is cornmeal, which is derived from corn kernels. The cornmeal is usually made from a specific type of corn called “zea mays everta,” which is a special kind of flint corn that “pops” when heated. This type of corn is ideal for making puffed corn snacks because of its hard outer shell and soft inner starch.
The cornmeal used in puffed corn snacks is often enriched with vitamins and minerals to enhance its nutritional value. Additionally, other ingredients such as vegetable oils, seasonings, and preservatives may be added to the cornmeal to give the puffed corn snacks their desired flavor and texture.
What is the process of puffing cornmeal?
The process of puffing cornmeal involves heating the cornmeal to a high temperature, typically around 200°C (392°F), under high pressure. This causes the water molecules inside the cornmeal to turn into steam, which builds up pressure and eventually causes the cornmeal to “pop” into a puffed shape. The heat and pressure are carefully controlled to ensure that the cornmeal puffs evenly and consistently.
The puffing process can be done using various methods, including extrusion, gun puffing, or toasting. Extrusion involves forcing the cornmeal through a heated die to create the puffed shape, while gun puffing involves using a high-pressure gun to puff the cornmeal. Toasting involves heating the cornmeal in a rotating drum to create a puffed texture.
