The objective of this work is to study the influence of drying methods and storage period in the industrial quality of wheat. Samples of wheat (Triticum aestivum, L.) produced in a cultivated plain were harvested with moisture near to 19 % (conventional harvest) . The grains were submitted to four drying conditions: drying with natural air, not forced, stationary drying

This research aimed to evaluate the natural contamination by fungi, production of mycotoxins, fatty acids composition and the intergranular CO2 concentration in oat grains stored in a hermetic system for 12 months. The oat grains were... more
This research aimed to evaluate the natural contamination by fungi, production of mycotoxins, fatty acids composition and the intergranular CO2 concentration in oat grains stored in a hermetic system for 12 months. The oat grains were harvested with 16% of moisture, being dried until 15%, 12% and 9% of moisture. Oat grains with 18% and 21% of moisture were obtained

This research was aimed at evaluating the effect of the relationship intermittence and the temperature of the drying air on the physiological and technological quality of oat grains stored in a conventional system for 12 months. Oat, UPF 18 cultivar, harvest in 2002/2003 was submitted to drying at three temperatures (65ºC, 85ºC, 110ºC) and three intermittent relations (1:2,5, 1:3,7, 1:5),

The aim of this study was to evaluate the energetic performance in the process of intermittent drying of white oat grains at three different air temperatures and final moisture. White oat grains (Avena sativa L.), UPFA 20 Teixeirinha cultivar produced at Palma Experimental Station of the Federal University of Pelotas, 2003/2004 crop, were submitted to intermittent drying at three temperatures

Aiming to verify the effect of air thermal handling in the stationary drying and the time of storage on the industrial performance and rice technological properties. For this, long-fine class grains "agulhinha", produced in irrigated system, on the south of Brazil, harvested with 22 % of moisture content, were submitted to four drying conditions: 1) Use of air did not

The aim of this work was to evaluate the effects of drying air temperature and final moisture in conservation and industrial quality of stored oat grains in conventional system for eight months. Grains from oat cultivar UPFA 20 Teixeirinha, produced in the Palma Experimental Station of UFPel, agricultural harvest of 2003/2004 harvest were subjected to three drying temperatures (60 ºC,

This study was done to evaluate the physicochemical properties and to quantify the residual silicon in flour from wheat grains treated with different dosages of DE and stored in a conventional system for 180 days. Samples containing 10.0kg of wheat grain were treated with 0.00, 2.00 and 4.00gkg−1 of DE and then homogenized and stored in cotton bags at 22°C

The objective of the work was to evaluate the effect of drying air temperature and intermittence relation (heating time: resting time) on the enzymatic inactivation and paste viscosity of oat. Oat, UPF 18 cultivar, produced in the Palma Experimental Field of University of Pelotas (UFPel), harvest of 2002/2003 was submitted at three drying temperatures (65ºC, 85ºC, 110ºC) and three intermittent relations (1:2.5, 1:3.75, 1:5 h:h), in rotational composed central delineation applicable to the response surface methodology (RSM). The grains were stored in conventional system and after the installation of the experiments, the chemical composition, residual activity of the enzymes lipase and peroxidase enzymes and paste viscosity were evaluated. The intermittent drying did not provoke substantial enzymatic inactivation in oat grains. The pasting viscosity of the oats did not change with drying temperatures and intermittence relation used. The content of lipids changed the properties of past...
