The objective of this work was to develop a new formulation for a snack made by thermoplastic extrusion from a mixture of broken rice flour and broken common bean flour, and assess the nutritional, sensory and technological potential of the new product. The broken common bean flour was added to the broken rice flour at a rate of 30%, and the snack was produced in a pilot scale single screw extruder. The extrusion parameters were fixed using three extrusion zones (at 40, 60 and 85 °C); screw speed of 177 rpm; feed rate of 292 g.min-1; and a circular matrix with a diameter of 3.85 mm. The snack sample was submitted to physicochemical, technological and sensory analyses. A significant effect of adding the broken common bean flour was observed in increasing the levels of protein and fiber in the snack, when compared with only broken rice flour. With respect to the technological characteristics, a bulk density of 0.17 g.cm-3 was obtained, expansion rate of 7.75 and instrumental hardness of 435.98 g.f. The formulation was well accepted, with an acceptance rate of 76% for overall impression. It was concluded that it was possible to produce extruded snacks by incorporating 30% of broken common bean flour into broken rice flour, resulting in gluten free products with good sensory acceptance and adequate nutritional value.

The present study aimed to characterize the physical and physical-chemical properties and perform sensory evaluation of ripe fruits of three banana cultivars of the subgroup 'Maçã ' at different stages of maturation. Bunches of Caipira, Thap Maeo, and BRS Tropical cultivars were harvested at stage 2 of color peel (green-mature) and stored at room temperature. They were evaluated at color peel stages 2, 3, 5, 7 with respect to length and diameter of the fruits. The following properties of the pulp were investigated: firmness, pH, soluble solids, titratable acidity and sugar concentration (reduced, not reduced and total). Fully ripe fruits were also analyzed regarding the sensory acceptance through the attributes aroma, pulp color, texture, and flavor of fruit. As the ripening progressed, acidity, soluble solids and sugars increased, factors responsible for the fruit flavor, as well as the decrease in fruit firmness and the pH reduction were observed for all cultivars. With respect to sensory analysis, the Tropical and Thap Maeo cultivars presented the highest average scores for all sensory attributes evaluated.
