background and objectives: kefiran (kef) is a water-soluble polysaccharide that can form transparent film however, it is brittle. therefore, in order to improve the mechanical properties of kefiran film, a mixture with other polymers can be offered. the expansion of mixed systems can propose kefiran and polyvinyl alcohol (pvoh) as a new composite film. materials and methods: solutions of 20 gra...

physical properties of fruits and vegetables are the subject of many researches because of its importance in designing of agricultural machinery. banana fruit is one of important fruit. in this study some physical properties of banana fruit (cavendish variety) were determined. properties which were measured included weight of whole fruit peel and pulp weight, dimensions, surface area and projec...

background and objectives: scolymus is one of most abundant plants of mountain areas iran, because of role in the digestion of food auxiliary is located the focus of attention consumers. in iran, more than 17 percent of crops in various stages of the supply becomes losses, which requires knowledge of physical properties, mechanical and hydrodynamic agricultural products. the existence of the in...

in this study, geometrical, gravimetrical and frictional properties of four common varieties of iranian canola seeds (namely: slm, hyola, okapi, orient), containing the mean moisture value of 6.5% (w.b.) were investigated. geometrical and gravimetrical properties included length, diameter, geometric mean diameter, sphericity, thousand seed mass, volume, true density, bulk density and porosity. ...
