Claims16
A process for the manufacture of an expanded food product, which consists essentially of the steps of:
- 1. providing a quantity of a particulate rusk material derived by baking a water-containing grain-based dough and thereafter comminuting the resultant baked product;
- 2.
A process for the manufacture of an expanded fried food product, which consists essentially of the steps of:
- 1. formulating a first water-containing dough by admixing water, yeast, and a grain flour selected from the group consisting of wheat, maize, corn and yellow corn;
- 2. baking said first dough;
- 3. reducing the resultant baked product of step (2) to a rusk material in particulate form;
- 4. formulating a second water-containing dough by admixing the particulate rusk material of step (3), water, raw starch and flavoring agents;
- 5. shaping said second water-containing dough by a forming operation selected from the group consisting of extrusion and sheeting out;
- 6. cutting the shaped dough into discrete pieces;
- and
- 7. subjecting the discrete pieces to frying in cooling oil under such time and temperature conditions as to effect expansion of said discrete pieces by at least 1.2 times to produce expanded food product items characterized by having a relatively more porous internal structure within a less porous external structure.
