This study arose from the need to meet request of consumers for healthy, ready-to-eat foods. The behavior pigmented rice was investigated during extrusion in terms nutritional (i.e., phenolic acids, anthocyanins and antioxidant capacity (AC)) physical starch pasting properties, texture, porosity biometric indices) properties. Snacks were produced brown, red, black rice, by means a co-rotating t...

Intermeshing co-rotating twin-screw extruders are very versatile because their screw configurations can be tailored both to the application and properties of materials used. Finding best configuration is one main purposes extrusion modeling, requires models that accurately predict conveying power consumption. The better process predicted, requirements final product met. We present novel predict...

Abstract Background and Objectives Intermediate wheatgrass ( Thinopyrum intermedium , IWG) is a perennial grain crop being explored for mainstream food applications. The impact of extrusion on the nutritional physicochemical characteristics IWG was investigated first time. Extrudates were produced using corotating twin‐screw extruder. Findings Extrusion resulted in slight decreases dietary fibe...

A combination of different levels of distillers dried grains processed for food application (FDDG), garbanzo flour and corn grits were chosen as a source of high-protein and high-fiber extruded snacks. A four-factor central composite rotatable design was adopted to study the effect of FDDG level, moisture content of blends, extrusion temperature, and screw speed on the apparent viscosity, mass ...

This study was conducted to investigate the effect of extrusion conditions (moisture content 20% and 30%, screw speed 200 and 250 rpm, barrel temperature 115℃ and 130℃) on the acidic polysaccharide, ginsenoside contents and antioxidant properties of extruded Korean red ginseng (KRG). Extruded KRGs showed relatively higher amounts of acidic polysaccharide (6.80% to 9.34%) than nonextruded KRG (4...

Abstract The paper presents the results of research on influence used plasticizing system structural and thermal properties thermoplastic starch (TPS). granulate was obtained by extrusion native in presence a using twin-screw extruder. Glycerol urea were as plasticizers various proportions. In order to evaluate effectiveness plasticization process, changes its chemical structure analyzed infrar...

The use of hot-melt extrusion for preparing homogeneous API-excipient mixtures is studied for miconazole-PEG-g-PVA [poly(ethylene glycol)-poly(vinyl alcohol) graft copolymer] solid dispersions with a 5 cm(3) table-top, twin-screw corotating microcompounder (DSM Xplore). Phase behavior of PEG-g-PVA, miscibility of miconazole in PEG-g-PVA and the partitioning of miconazole between PEG and PVA amo...

Peptides from soybean meal were subjected to extrusion and the effects of extrusion conditions, such as moisture of the materials, barrel temperature, screw speed and nozzle diameter, on the antioxidant properties were studied. The extrusion conditions that had the highest free radical-scavenging activity were further separated into three peptide fractions (using ultra filtration); hydrolysis o...

The application of twin screw extrusion (TSE) as a scalable and green process for the manufacture of cocrystals was investigated. Four model cocrystal forming systems, Caffeine-Oxalic acid, Nicotinamide-trans cinnamic acid, Carbamazepine-Saccharin, and Theophylline-Citric acid, were selected for the study. The parameters of the extrusion process that influenced cocrystal formation were examined...

The aim of this study consisted of manufacturing renewable binderless fiberboards from coriander straw and a deoiled coriander press cake, thus at the same time ensuring the valorization of crop residues and process by-products. The press cake acted as a natural binder inside the boards owing to the thermoplastic behavior of its protein fraction during thermopressing. The influence of different...
