| 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... |

| 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... |

| Two experiments were carried out to determine the nutritional value and verify piglets' performance in the nursery phase fed with diets containing common corn (CC), extruded common corn (ECC), high-lysine corn (HLC), extruded high-lysine corn (EHLC), high-oil corn (HOC) and extruded high-oil corn (EHOC). In the total digestibility trial 14 barrows averaging 6.49 ± 0.16 kg initial body weight were allotted in metabolism cages, distributed in a randomized design with seven diets, six replicates, and one piglet per experimental unit. The values of digestible energy (DE), as well as metabolizable energy (ME) as-fed basis for CC, ECC, HLC, EHLC, HOC and EHOC were: 3,428 and 3,327 kcal/kg; 3,439 and 3,355 kcal/kg; 3,533 and 3,414 kcal/kg; 3,515 and 3,427... |

| 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... |

| Effect of extrusion conditions on pasting properties (Cold peak (I), Raw peak, Hold, Breakdown, Final viscosity, Set back, Peak time and Cold peak (II)) of modified corn grit from extrusion process were investigated using Rapid Visco Analyzer (Software: Thermocline for windows Version 2.1 with extrusion profile method). A co-rotating twin screw extruder was used for modified corn grit with three operating factor such as particle size (250, 500 and 600 μm), feed moisture content (14, 16 and 18%) and screw speed (300, 350 and 400 rpm). Increasing feed moisture content results in extrudates with a higher pasting viscosity, but otherwise increasing screw speed shows with a lower response. Particle size has a slightly effect for this experiment. All of... |

| 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... |

| 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... |

| 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... |

| Legumes are prime source of plant proteins, calories and other nutrients. Extrusion cooking of legumes increases the digestibility of legume protein. Extrusion technology has been applied to generate analogues of foods made from animal products, as well as snacks using blends of various plant raw materials e.g. oil seeds [soybeans, peanut with a cereal flour]. Present work was under taken for producing extruded product from pigeon pea. The legumes viz. pigeon pea and Bengal gram were cleaned and ground to required particle size by multipurpose grinder mill to pass through sieve ASTM No. 20. The moisture content of sample was adjusted to 14% moisture level (w.b.). Before extrusion, the feed was allowed to come to ambient temperature and then remixed, after... |

| 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. |
