| ABSTRACT: This study aimed to evaluate potato flour from 'Ibituaçú' cultivar as raw material for extrudates. Potato flour was processed in a single-screw extruder following central composite rotational design for three factors, being considered as independent parameters: temperature in the third zone, humidity and screw speed. The products obtained were characterized by expansion index (EI), specific volume (SV), water solubility index (WSI), water absorption index (WAI), hardness (H), color (L*, a* and b*). Results showed an effect of the independent parameters on the extruded physical characteristics. The parameters varied from: 3.22 to 5.47 (EI); 2.08 to 11.23 mL g-1 (SV), 32.88 to 63.72% (WSI), 4.02 to 8.97 g gel g-1 (WAI), 7.54 to 29.85 kgf (H), 53.89... |

| ABSTRACT Whey has proteins of high biological value, which has been used as an ingredient in the elaboration of yogurt, milk beverages and as protein concentrates. Food extrusion stands out as one of the most efficient cooking techniques, allowing a number of product types, from soluble flour to convenience products, such as snacks, which have high acceptability by the consumers. Products processed by extrusion, such as those expanded by frying (pellets), have high carbohydrate content, and its enrichment with protein can favor its nutritional aspect. This study aimed to use the whey protein concentrate (WPC) in combination with corn grits in the preparation of pellets. Absolute density, density of expanded pellets, color, crispness index, and pellet... |

| Short cooking time and ability to blend varieties of food ingredients have made extrusion cooking a medium for low-cost and nutritionally improved food products. The effect of moisture, extrusion temperature and amount of turmeric flour mixed with cassava flour on physical characteristic of puffed snacks was evaluated in this work. Extrusion process was carried out using a single-screw extruder in a factorial central composite design with four factors. Results showed effect of extrusion parameters on dependents variables. High expansion, low browning, low water solubility index, intermediate water absorption index and high crispness desirable characteristics to puffed snacks are obtained in conditions of 12% moisture, 5% turmeric flour, 105º C of... |
