Abstract:
A method of puffing a food starch material capable of becoming amorphous into a food starch material product comprising:preparing a flour of the food starch material; gelatinizing the floured food starch material in an extruder under a pressure and temperature; extruding the gelatinized food starch material; forming pellets from the extruded food starch material; placing the pelletized food starch material into a puffing chamber having a pressure and temperature; increasing the pressure and the temperature in the chamber until the pelletized food starch material is amorphous; quickly reducing the pressure in the chamber to cause a volumetric expansion of the amorphous food starch material; and constraining expansion of the amorphous food starch material in at least a first dimension, while permitting expansion of the amorphous food starch material in at least a second dimension.
