Corn-based expanded extruded snacks containing wheat bran as dietary fi ber source were evaluated with respect to instrumental hardness, expansion index and color (L* - lightness). Internal cell structure was observed through Scanning Electron Microscopy (SEM). Snacks were produced following a 23 complete factorial design, in a single screw extruder (model GNF 1014/2, BRABENDER, Germany). The three independent variables studied were: moisture (from 16.3 to 29.7%); temperature of the 2nd and 3rd… 
Extruded snacks from whole wheat supplemented with textured soy flour: Effect on instrumental and sensory textural characteristics.
The effect of adding textured soy flour and whole wheat flour to refined wheat flour in the production of extruded snacks and expanded with hot air was evaluated and showed that the level of substitution of WWF had a significant effect on the hardness perceived by the panelist during sensory evaluation.
Effect of extrusion conditions on the structural properties of corn extrudates enriched with dehydrated vegetables
Abstract 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
Physical and Sensory Properties of High Added Value Rice Extrudates
Rice extrudates enriched with freeze dried carrot powder were produced using a twin screw extruder, operated at various conditions of screw speed (150–250 rpm) and temperature (140–180 °C). Different
Production of high quality expanded corn extrudates containing sesame seed using response surface methodology
Sesame seed, which possess exceptional nutritional and antioxidant properties, was incorporated into corn expanded extrudates to improve their nutritional quality. Expanded corn extrudates with 0, 15
Thermal, textural, and physicochemical analysis of corn extrudates enriched with broccoli or olive paste
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
‘The effect of inulin addition on structural and textural properties of extruded products under several extrusion conditions’
There is a significant effect of extrusion temperature, screw speed, feed moisture content and inulin concentration on the final properties of the extrudates, both density and maximum stress increased when moisture content increased, while they decreased when extrusions temperature and screw speed increased.
Development of whole grain wheat flour extruded cereal and process impacts on color, expansion, and dry and bowl-life texture
Abstract The use of whole grains in extruded products is of great interest for obtaining healthy breakfast cereals (BC). The objective of the study was to investigate the effects of feed moisture and
Physical properties of extruded corn grits with corn fibre by CO2 injection extrusion
Abstract Corn grits and corn fibre mixed at different ratios (0/100, 15/85 and 30/70) were extruded at different melt temperature (90, 105 and 120 °C) using extrusion with and without CO 2 injection.
Fortification of extruded snacks with chitosan: Effects on techno functional and sensory quality.
It is concluded that 1% chitosan can be incorporated in Acetes based extruded snacks for an increased level of functionality.
Third generation snacks manufactured from orange by-products: physicochemical and nutritional characterization
A mixture of orange vesicle flour, commercial nixtamalized corn flour and potato starch was extruded using a Brabender Laboratory single screw extruder (2:1 L/D). The resulting pellets were expanded


Corn Bran as a Fibre Source in Expanded Snacks
Abstract The potential use of corn bran as a component for manufacturing snacks through thermoplastic extrusion was investigated. Corn bran (180, 250 and 320 g/kg) was blended with corn meal

ABSTRACT: The effect of processing variables, including screw speed (200,300, and 400 rpm), moisture content (18, 19.5, and 21%), and four different percentages (55,70,85, and 100%) of oat flour, on
Expanded extrudates from corn starch-lamb blends: process optimization using response surface methodology.
A central composite second-order design was used to study the effects of feed moisture, process temperature, and screw speed on expansion ratio and shear-force of extrudates from blends of corn starch and lean lamb and the predicted models were adequate when tested by the lack of fit and coefficient of determination.
