| 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... |

| Abstract Nowadays the demand for practical food like snacks increases worldwide, however the nutritional value in most these formulations is reduced. Due to its chemical composition with high protein concentration, the microalga Spirulina has been used on the production of enriched foods. The present study aimed to evaluate the effects of Spirulina sp. LEB 18 addition on snacks formulations and extrusion conditions on the physicochemical and structural properties of snacks. Protein concentration and physical properties such as expansion index, bulk density, hardness, water absorption index, water solubility index and color were determined. The results showed that the addition of Spirulina sp. LEB 18, temperature in the last zone of the extruder and feed... |

| The opportunity to supplement common cassava biscuits with a product of higher nutritional value meets consumer expectations. In this work it was studied the effects of process parameters and flaxseed addition on physical properties of expanded snacks. Extrusion process was carried out using a single screw extruder in a factorial central composite rotatable design with four factors: flaxseed flour percentage (0-20%), moisture (12-20%), extrusion temperature (90-130 °C) and screw speed (190-270). The effect of extrusion variables was investigated in terms of expansion index, specific volume, water absorption index, water solubility index, color parameters (L*, a* ,b*) and hardness. The data analysis showed that variable parameters of the extrusion process... |

| Abstract The present study aimed to develop extruded corn breakfast cereal enriched with whole peach palm flour. A 22 central composite rotatable design was used, and the cereal was processed in a ZKS-30 co-rotational twin-screw extruder (Werner and Pfleiderer), followed by its physicochemical, technological and microbiological characterization. The technological analysis revealed higher expansion and lower hardness as well as adequate lightness and water-absorption and water-solubility indices of the breakfast cereal at low moisture and intermediate peach palm flour contents. Moreover, 3.84% moisture, 0.63% ash, 6.09% protein, 0.39% lipids, 85.94% carbohydrates, 3.11% fiber and 246 RE of total carotenoids were found in the physicochemical analysis, and... |

| The demand for low-fat beef products has led the food industry to use fat substitutes such as modified starch. About 14% of broken rice is generated during processing. Nevertheless, this by-product contains high levels of starch; being therefore, great raw material for fat substitution. This study evaluated the applicability of chemically and physically modified broken rice starch as fat substitute in sausages. Extruded and phosphorylated broken rice was used in low-fat sausage formulation. All low-fat sausages presented about 55% reduction in the fat content and around 28% reduction in the total caloric value. Fat replacement with phosphorylated and extruded broken rice starch increased the texture acceptability of low-fat sausages, when compared to... |

| A blend of 50% Potato Starch (PS), 35% Quality Protein Maize (QPM), and 15% Soybean Meal (SM) were used in the preparation of expanded pellets utilizing a laboratory extruder with a 1.5 × 20.0 × 100.0 mm die-nozzle. The independent variables analyzed were Barrel Temperature (BT) (75-140 °C) and Feed Moisture (FM) (16-30%). The effect of extrusion variables was investigated in terms of Expansion Index (EI), apparent density (ApD), Penetration Force (PF) and Specific Mechanical Energy (SME), viscosity profiles, DSC, crystallinity by X-ray diffraction, and Scanning Electronic Microscopy (SEM). The PF decreased from 30 to 4 kgf with the increase of both independent variables (BT and FM). SME was affected only by FM, and decreased with the increase in this... |

| 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... |
