Working principle of the puffed food machine

The starch in the cereal raw material will be quickly gelatinized during the puffing process, which significantly increases the hydration rate of the protein and carbohydrates. The gelatinized starch will not be aged after being left for a long time.

This is because after the starch is gelatinized, its crystallite bundle structure is destroyed, and after the temperature is lowered, it is not easy to associate with the crystallite bundle again, so it is not easy to age.

As an economical and practical new processing method, the puffing technology of puffed food machines is widely used in food production and has been rapidly developed.
