Abstract: A process for manufacturing a fiber fortified foodstuff that includes preparing the foodstuff and then topically applying supplemental fiber. In particular, puffed snack products are prepared by mixing cereal with a fiber premix and sufficient moisture to form an extrudable dough base. The dough base is cooked in a cooking extruder and then extruded to form a wet puff which is dried and then coated with an oil slurry. A flavor premix which includes supplemental dietary fiber, particularly a soluble fiber, is topically applied to the oil coated dry puff to form a fiber fortified, puffed snack product.
