The study examined the effect of moisture content on maize shelling speed using a manually operated hand Sheller (cone type). Twenty (20) unthreshed maize cob samples (A-J) were used for the study. The samples were analysed in the laboratory for parameters such as weight of samples before and after drying, moisture content and shelling speed. The result indicated that sample J, after sixty nine...

the presented study shows a simple way for optimization of extrusion process, which was used for deterioration of cyanogenic glycosides – antinutritive components of linseed, with minimum damage of essential alpha-linolenic acid (ala) at the same time. extrusion of the material was done on a laboratory single screw extruder. content of hydrogen cyanide (hcn) as a measurement of cyanogenic glyco...

Background: Edible films and coatings are biodegradable that can preserve the quality and extend the shelf life of foods. The aim of this study was to investigate the physical and mechanical properties, and antimicrobial activity of carboxymethyl cellulose (CMC) film containing Artemisia sieberi Essential Oil (AEO). Methods: The studied parameters were the antibacterial activity and physical p...

In most studies, moisture sorption into amorphous foods is expressed as a change in the bulk moisture content, which does not provide detail on how a moisture front moves into the food. This study was targeted towards characterization of the moisture behavior in amorphous saccharide materials of different molecular weight (MW), glass transition temperature (Tg) and moisture content. Various sug...

The production of microcystins (MC) from Microcystis aeruginosa UTEX 2388 was investigated in a P-limited continuous culture. MC (MC-LR, MC-RR, and MC-YR) from lyophilized M. aeruginosa were extracted with 5% acetic acid, purified by a Sep-Pak C(18) cartridge, and then analyzed by high-performance liquid chromatography with a UV detector and Nucleosil C(18) reverse-phase column. The specific gr...

An NMR imaging technique published in literature was adapted to investigate the role of glass transition on Fickian and non-Fickian modes of moisture transport in pasta. The modified technique allowed measuring the moisture distribution in samples with initial moisture content from 10% to 50% or higher. A change in slope in the signal intensity versus moisture content curves indicated different...

in the past decades, environmental pollution caused by plastic packing materials, restrictions of petroleum resources and their high price attracted many researchers to produce biodegradable packaging materials. poor mechanic properties and high water vapor permeability are two main defects of biodegradable polymers. nanotechnology is a modification method in this case. in the current study, th...

The condition of oil-paper insulation is closely related to the life expectancy of a transformer. The accurate results of oil-paper have not been obtained due to the impact of influencing factors. Therefore, in order to improve the evaluation accuracy of oil-paper insulation, in this paper, oil-paper samples which were prepared with different aging and moisture content were analyzed by frequenc...

To estimate the order of importance of factors affecting the stability and maturation of compost, cow feces and maize stalks were co-composted at different aeration rates “AR” (22, 44 and 66 L kg-1 DM . min-1) of C/N ratios (16, 19, 22), and moisture contents “MC” (60 %, 65 %, 70 %). A composting process was monitored by physical and chemical methods. The thermophilic phase with all treatments ...
