Different processing methods can be applied to pearl millet (Pennisetum glaucum (L.) R. Br.) grains, like milling, decortication, and extrusion. Significant nutrient losses happen in the production of refined flours by removing the germ and bran, therefore, the use of whole grains in the bakery industry has increased in Brazil. Thus, the objective was to produce refined and whole-grain pearl millet flours, cooked by the thermoplastic extrusion process or not, and to characterize them in terms of granulometry, color, and water absorption index (WAI). The whole grains of pearl millet (ADRG 9070 – Atto Sementes®) were cleaned and the decortication, when applied, was made by mechanical abrasion. To obtain the extruded flours, the raw flours (decorticated or not) were fed at 10 kg.h-1 into a twin-screw extruder with speed of 250 rpm and temperature profile of 25, 25, 60, 90, 120, 120, 120, 90, 60 and 60 ºC, the extrudates were dried in an air circulation oven and milled. The raw whole-grain flour presented a lower value of L* (71.74), due to the reduced content of pigments responsible for a grayish color, and the extrusion did not change the luminosity (p>0.05) of the flours. The raw whole-grain flour showed the highest level (19.3%) of coarse particles, while the raw refined flour showed a higher amount (54.37%) of fine particles. Regarding the extruded flours, similar percentages of fine, intermediate, and coarse particles were obtained (p>0.05). The refined samples showed a lower WAI than the whole-grain flours, because of the reduction in dietary fibers. The extrusion increased (p<0.05) the WAI of the whole-grain flour. It is concluded that the decortication and the extrusion affected the characteristics of the flours and both extruded flours present the potential to be used in the production of different foods, such as in the bakery industry.

The effect of particle size (PS), cultivars (C), and their interactions (PS × C) on the hydration of whole wheat flour (WWF) intended for cookie production was evaluated by different approaches. Three Brazilian wheat cultivars and three particle sizes were evaluated. Total arabinoxylans content was affected by PS, increasing up to 6.18 times with the reduction in particle size. Water-soluble arabinoxylans were more influenced by the cultivar. The water absorption capacity by farinograph indicated that the PS had a greater influence, with high absorption in fine particle size flour. Water absorption based on swelling capacity and absorption kinetics by Enslin-Neff device evidenced high water absorption for coarse particle size flour, regardless the cultivar. ORS Vintecinco cultivar demonstrated the best hydration properties and desired quality for short-dough cookies. The different methods to predict the hydration properties of the flours resulted in different behaviors, demonstrating that the presence of outer layers of the grain of WWF promotes distinct mechanisms in the water absorption capacity, which are significantly influenced by genotype and particle size factors. |
