The flow of ruminal undegradable protein (RUP) to the small intestine can be increased if ruminal degradation of dietary protein is reduced. The objective of this study was to evaluate the effect of extrusion on ruminal degradability of dry matter (DM) and crude protein (CP) from dehulled lupin (Lupinus albus L.) (DL) and rapeseed (Brassica napus L.) meal (RM). Unextruded soybean (Glicine max L.) meal (SBM) was used as a control. The DL was extruded at 130 ºC with 20% moisture and RM was extruded at 120 ºC with 20% moisture. Ruminal degradability was evaluated in situ by incubating feed samples for 2, 4, 8, 12, 24, and 48 h of fermentation in the rumen using three rumen-fistulated dairy cows. Values of CP soluble fraction (a) in SBM, DL, extruded... |

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... |

O objetivo deste trabalho foi otimizar as condições de processamento por extrusão termoplástica de misturas de farinhas de mandioca, de banana verde e de castanha-do-brasil, visando à obtenção de uma farinha pré-gelatinizada para consumo na forma de mingau. Para a obtenção das farinhas pré-gelatinizadas, utilizou-se um delineamento do tipo composto central rotacional 23, contendo 3 pontos centrais e 6 axiais. Os ensaios foram processados em extrusor monorrosca. Duas formulações destacaram-se em termos nutricionais (elevado teor proteico), tecnológicos e aceitação sensorial: a Formulação 6 (40% de farinha de mandioca, 20% de farinha de banana verde, 40% de farinha de castanha-do-brasil, 14% de umidade, temperatura de 100 °C) e a Formulação 16 (40% de... |

El contenido de calcio (Ca) y de compuestos que afectan su absorción son relevantes en dietas ricas en harinas integrales y frutos secos, tanto en vegetarianos estrictos, individuos con intolerancia a lácteos, como en celíacos. Se determinaron Ca, fibra dietaria y perfil de inositoles fosfato (IP) en harinas integrales/refinadas y/o extrudidas de cereales (trigo, maíz, arroz, sorgo), pseudocereales (trigo sarraceno, amaranto), leguminosas (arveja), oleaginosas (soja, lino). Se cuantificó Ca por espectrometría de absorción atómica, fibra dietaria por método enzimático-gravimétrico y perfil de IP por HPLC. Mediante factores de conversión, se calculó el contenido de ácido fítico (AF) y la relación molar AF/Ca como indicador de su disponibilidad potencial. El... |

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... |

Considering the importance of cassava starch for Brazilian industries, the current work aimed at evaluating the effects of extrusion parameters on the physical characteristics, mainly viscosity properties of extruded cassava starch. A factorial central composite design (2³) with three independent variables and the response surface methodology were used to evaluate the results of expansion index, specific volume, water absorption index, water solubility index, color and paste properties, according to the variations in the moisture content, barrel temperature and screw speed. Results indicated that barrel temperature influenced the expansion index, specific volume, water absorption index, all the color parameters, the initial viscosity, peak and final... |

Effect of particle size, feed moisture content and screw speed with different levels (250, 500 and 600 μm; 14, 16 and 18%; 300, 350 and 400 rpm) using a co-rotating twin screw extruder on physical and chemical properties (color, expansion ratio, bulk density, water absorption index (WAI), water solubility index (WSI), rheological and amylose/amylopectin content) of modified extruded products was investigated. Increasing feed moisture content results in extrudates with a higher bulk density, WAI and cold paste viscosity, but reduced the expansion ratio and WSI. Increasing particle size caused with a brighter color and higher amylose content. In case of higher screw speed increased the expansion ratio, WSI and amylopectin content. |
