Article
Phenolic content, antioxidant activity and sensory characteristics of vegetable-enriched extrudates were investigated as a result of extrusion conditions, including extrusion temperature (140-180 °C), screw rotation speed (150-250 rpm) and feed moisture content (14-19 % w.b.). Broccoli flour and olive paste was used in mixtures with corn flour at a...

Following the tendency of replacing common food snacks with healthier food products, extruded snacks with corn flour and broccoli (4-10%) or olive paste (4-8%) were investigated in this study. The effect of material characteristics, including feed moisture content (14-19%), and broccoli or olive paste concentration, and extrusion conditions, includ...
Article
The growing consumers’ demand for healthier snacks is of high importance and is driving research and industry towards developing novel ready to-eat expanded products. Thus, it would be interesting to enrich these products with additives that possibly lead to highly nutrient products. In the present study, extruded snacks based on corn flour enriche...
Article
The present study examines the addition of dehydrated broccoli or olive paste to corn flour for the production of extrudates with increased value and superior quality. Extrudates were prepared using a twin-screw extruder, operated at different conditions, including screw speed (150 rpm, 200 rpm, 250 rpm) and extrusion temperature (140 °C, 160 °C, 1...
Article
Structural properties, such as apparent density, true density, expansion ratio and porosity, of extruded corn grits enriched with plant fibers were measured. The effect of extrusion conditions, including feed rate (0.7–1.9 g/s), feed moisture content (13–19% wet basis) and extrusion temperature (150–230°C) on structural properties of corn based ext...

Physical weathering is usually responsible for the degradation of maxillofacial prosthetic elastomers and the replacement of prostheses. The purpose of this study was to investigate the effects of outdoor weathering on the physical properties of four nonpigmented facial prosthetics after 1 year of exposure. In addition, simple mathematical models w...
Article
The effect of moisture content on structural properties such as apparent density, true density and porosity was investigated in this work for various vegetables after conventional drying. Samples of twelve different fresh vegetables (mushroom, green pepper, courgete, spinach, celery, leek, onion, tomato, garlic, carrot, pea, and corn) were dehydrat...

A Fe-doped titanium dioxide (Fe-TiO2) was prepared using hydrothermal method and used for degradation of phenol from aqueous solution. The samples were characterized by X-ray diffraction (XRD) and showed a presence of both TiO2 and Fe2O3 peaks. The photocatalytic activity of Fe-TiO2 catalyst was evaluated for oxidation of phenol in aqueous solution...
Chapter
Density, shrinkage, and porosity are included in the mass- and volume-related properties that constitute one of the main groups of mechanical properties along with rheological, morphological, acoustic, and surface properties (Rahman and McCarthy, 1999). The importance of these properties is illustrated by the following applications:. Process design...
Article
The effect of extrusion conditions, including feed rate (2.52-6.84 kg/h), feed moisture content (13-19% wet basis), screw speed (150-250 rpm), and extrusion temperature (150-230 degrees C) on structural properties of corn-legume based extrudates was studied. Four different types of legumes, chickpea, mexican bean, white bean, and lentil were used t...
Article
The classical problem of heat recovery from convective dryer exhaust air is considered under modern easy-to-programming techniques towards effective decision making environment. Heat exchangers as well as heat pumps are considered versus various dryer performance characteristics.
