Expansion technology belongs to physical processing technology

Puff food adopt grain, beans, potato nuts, subclass as raw material. It is one of kinds of crispy food which made after extruding,baking or frying puff.etc. Is conducive to digestion and absorption of nutrition material itself.

Puffing, here means the process that the use of phase change and the principle of the thermal effect of the gas, make the water inside of material moisture rapid heating vaporization, supercharged expansion, and rely on the expansive force of the gas to drive components in the structure of the polymer material change, thus making it become the reticular structure characteristics, finalize the design of porous material

Thus, puffing technology belong to the physical processing technology.It just change the shape l, state, and molecular structure in the material of raw material. Puffing technology not only improve the taste and eating, but also make grains and raw material itself with higher survival rate and digestive rate of nutritional ingredients. It is convenient to eat and easy to store. It also can be used as the staple food of dietary nutrition supplement.
