| Conduziu-se este trabalho,com o objetivo de estudar as propriedades funcionais tecnológicas de extrusados de terceira geração obtidos de misturas de farinhas de pupunha (Bactris gasipaes Kunth.) e mandioca (Manihot esculenta Crantz), por meio das análises de densidade aparente, índice de absorção de água, índice de solubilidade em água e viscosidade de pasta (RVA). Os extrusados foram formulados, adicionando-se 15, 20 e 25% de farinha de pupunha à farinha de mandioca, sendo processados em extrusora monorosca, escala piloto. Os parâmetros de extrusão foram fixos, utilizando-se cinco zonas de extrusão com temperaturas de 30ºC, 40ºC, 60ºC, 65ºC e 70ºC; velocidade do parafuso 177rpm; taxa de alimentação 292g/min e matriz laminar de 1mm. Os extrusados de... |

| Rice cooking quality is usually evaluated by texture and stickiness characteristics using many different methods. Gelatinization temperature, amylose content, viscosity (Brookfield viscometer and Rapid Visco Analyzer), and sensory analysis were performed to characterize culinary quality of rice grains produced under two cropping systems and submitted to different technologies. All samples from the upland cropping system and two from the irrigated cropping system presented intermediate amylose content. Regarding stickiness, BRS Primavera, BRS Sertaneja, and BRS Tropical showed loose cooked grains. Irrigated cultivars presented less viscosity and were softer than upland cultivars. Upland grain samples had similar profile on the viscoamylografic curve, but... |

| Although Brazil is a country of tradition in both the production and consumption of coffee, the most of the coffee is consumed as a beverage, which reduces greatly the competitiveness on international market, for reducing the chances of supplying the product under other forms of consumption. Owing to that, the aim of this study was developing a precooked mixed flour containing coffee powder and rice for use in coffee flavored products. Mixtures of rice and coffee in the proportions of 900:100, 850:150 and 800:200 g, respectively, were processed in a single screw extruder (Brabender DS-20, Duisburg, German) and the effect of the extrusion process on the variables moisture content (16%, 18% and 20%) and temperature in the third extruding zone (140 °C, 160 °C... |
