Chemical composition and functional properties of malted corn flours BABT
Grossmann,Maria Victória E.; Mandarino,José Marcos G.; Yabu,Márcia Cristina.
Flours with different physicochemical and functional properties were obtained from malted corn. Response surface methodology (RSM) was used to study the effects of malting time (1,3, 5 days), malting temperature (20, 25, 30º C) and gibberelic acid concentration (0.0; 0.5; 1.0 %) on these properties. The chemical composition and paste viscosity of flours were significantly affected by malting time and temperature, while water solubility index (WSI) and water absorption index (WAI) varied only with malting time. Gibberelic acid did not significantly influenced any of the studied properties. Germination at 20-25ºC for 3 days was recomended to obtain corn flour with high WAI, low viscosity and medium WSI, without excessive loss of proteins.

Consumer attitudes toward GM food with hypothetical functional characteristics AgEcon
Marin, Floriana; Notaro, Sandra.
Since their introduction in the early 1990s, genetically modified organisms in agriculture tended to emphasize improved yield. Europeans, perceiving unacceptable risk and too little benefit, resoundingly disapproved of GMO use in agro-food processes. More recently, research has turned to developing products that use GMO components that better match consumer interest, including nutritionally enhanced foods, environmentally friendly crops, and other areas. The question that arises is whether Europeans perceive that the new, prospective benefits outweigh the olds risks, opening the market to such products. This paper investigates consumer preferences for a number of hypothetical genetic modifications in a widely consumed food product: yoghurt. We explore the...

Effect of milling process on functional properties of legumes Thai Agricultural
Nipat Limsangouan; Seiichiro Isobe.
This study demonstrated the effect of milling processing (screw crushing, hammer milling and jet milling) on functional properties, such as antioxidant capacity, total phenolic content and resistant starch content of three legumes (broad beans, black soybeans and green beans). The results showed that broad beans possessed the highest antioxidant capacity and resistant starch content. Black soybeans had the highest total phenolic content. Different milling processes changed the functional properties of samples (p<0.05) depending on the particle size of the flour and the volume of the flush air operation. The grinding process, producing a smaller particle size and lower volume of flush air had higher functional properties than the others processes....

Effect of treatment with alkaline hydrogen peroxide associated with extrusion on color and hydration properties of oat hulls BABT
Galdeano,Melicia Cintia; Grossmann,Maria Victória Eiras.
An incomplete factorial design with three independent variables at three levels of variation was used to evaluate the effect of the treatment with alkaline hydrogen peroxide concomitant with extrusion on some properties of oat hulls. The independent variables were hydrogen peroxide level, feed moisture and extrusion temperature. The dependent variables were water retention capacity (WRC), swollen volume (SV) and color. The analysis of variance showed that temperature was the most important variable for the hydration properties. The highest values of WRC and SV were obtained when oat hulls were processed in the condition of 7% hydrogen peroxide, 32% feed moisture and 90ºC extrusion temperature. Modified hulls had a WRC 70% higher and SV 55% higher than the...
