drying foodstuffs can have negative effects on quantitative and qualitative characteristics of the products, including porosity and bulk density. therefore, novel technologies can be used to improve these characteristics. in this study, apparent density changes during drying grapes pretreated with ultrasound for 10, 20 and 30 minutes, and carboxymethyl cellulose (cmc) at three concentrations of...

the aim of this study was to investigate the effect of ultrasound and drying pretreatments on apparent density as well as modeling apparent density during deep-fat frying of potato slices. ultrasound pretreatment was performed at 28 and 40 khz for 15 min and drying pretreatment were conducted at 80°c for 8 and 15 min. then, the frying process was done at 150, 170 and 190°c for 60, 120, 180 and ...

effect of sucrose replacement with date syrup powder on physiochemical properties of sponge cake such as specific gravity, volume, apparent density, solid density, porosity, symmetry, moisture content, water activity, crust color and textural firmness was studied. batter specific gravity of the control sample was higher than that of other samples. sucrose replacement with 100% of date syrup pow...

In this work, hydroxyapatite/silica nanopowders were granulated to fabricate plasma sprayable feedstocks. For this purpose, the wet powders obtained by heating a hydroxyapatite/silica slurry were stirred and sieved. To realize the feedstock application in the plasma spray process, powders were deposited on titanium substrate. The morphology of granulated feedstock and sprayed coating was ...

the study was consequently investigated effect of different tanning methods on apparent density, thickness, tensile strength and also extension percentage in three different tanning (chromic, alum and vegetable) of grown part of ostrich skins (n = 15; 12 to 14 months). average apparent density and thickness of leathers were 0.7 ± 0.0gr/cm2 and 1.7 ± 0.1 mm, respectively. the breaking load, tens...
