Patent ID: 8163324

Claim:
An expanded, extrusion cooked snack having a high resistant starch content comprising at least one flour, and a gelatinized, starch based bulking agent, the amount of said bulking agent being at least about 30% by weight based upon the weight of said bulking agent and said at least one flour, said bulking agent comprising at least 30% by weight of an amylase-resistant starch type III having a melting point with an endothermic peak temperature of at least about 140° C. as determined by modulated differential scanning calorimetry (MDSC), the water-holding capacity of said starch-based bulking agent being less than 3 grams water per gram of said starch-based bulking agent, said snack being extrusion cooked and having an average peak force brittleness of at least about 3000 grams, and an average peak distance brittleness of less than about 4 mm, and a bulk density of from about 0.25 g/cm 3 to about 0.45 g/cm 3 .
