Abstract The extraction of bioactive compounds from malted quinoa flour using different water/ethanol mixtures under subcritical conditions was performed, and two mathematical models to describe the kinetics were compared. variables evaluated temperature, solvent mass flow rate composition, best selected a screening design. extract with highest antioxidant activity 95% inhibition DPPH, 2084 mg ...

OBJECTIVES Compare glycaemic response of foods prepared with finger millet flour, using traditional stone grinding and industrial milling. DESIGN Crossover study. PARTICIPANTS Healthy volunteers (n=11) consisting of five males and six females), aged between 20 and 30 years, with a body mass index of 18.5-23.5 Kgm-2. MAIN OUTCOME MEASURES Blood glucose concentration was measured at fasting...

Polypropylene/wood flour composites were melting compounded in an internal mixer at 190°C and 60 rpm rotor speed and then samples were fabricated by injection molding. Effects wood flour content on the physical properties of composites was investigated. For this purpose, hardness, water absorption and thickness swelling of samples was determined at different levels of wood flour content. The re...

Consumption of unrefined whole flour is thought to affect mineral bioavailability because it contains high levels of fibre and phytic acid. The present experiment was designed to study the absorption of minerals from diets based on wholewheat flour and white wheat flour in rats. Two groups of male Wistar rats were fed on the diets for 3 weeks and absorption and tissue retention of minerals were...

Wheat grain and its products are widely consumed as fodder and basic daily food stuffs in Kyrgyzstan. Mycobiota is known to produce hazardous effects to a consumer since it produces mycotoxins. Henceforth, mycobiota starting from the field stage to flour, grain and flour samples were selected for mycological analysis from eight sites of flour manufacture: grain stored in storehouses before mill...

Potassium methyl siliconate (PMS) was investigated as a new nano modifier of wood fiber and wood flour to improve the compatibility between the fiber/flour and the plastic matrix in fiber reinforced plastic composites. Before injection molding, bleached and brown pulp fibers and mixed species wood flour were pretreated in PMS solutions. The morphology of the treated and untreated fiber and flou...

the effect of shear rate on dissolution of carbon dioxide in viscoelastic wheat flour matrix and cell density in a glass barrel twin screw extruder is investigated. it is found that by increasing the shear rate there will be a decrease in the required thermodynamic conditions and hence, it improves blowing agent dissolution and increases the cell density. shear rate breaks up big bubbles and he...

The study was carried out in order to find out the effect of substitution of wheat flour with sweet potato flour of two local varieties (Local Sada and Local Lal) on the quality of bread. This study was also concerned with the analysis of proximate compositions of sweet potato and results showed that, fresh local sada and local lal sweet potato varieties contained moisture 70.10 and 66.78%; ash...

Tef grain is becoming very attractive in the Western countries since it is a gluten-free grain with appreciated nutritional advantages. However there is little information of its functional properties and starch digestibility and how they are affected by variety type and particle size distribution. This work evaluates the effect of the grain variety and the mill used on tef flour physico-chemic...
