Influence of Osmotic Agent Concentration and Drying Temperature on the Osmotic Dehydration of Pomelo
Advanced Materials Research, 2012This research aimed to study on the optimum condition for osmotic dehydration of pomelo. The experimental procedure was divided into 2 sections. For first section, the effect of sucrose solution concentration (50, 60, and 70 oBrix) on osmotic rate and moisture content of osmotic dehydrated pomelo were evaluated.

Concentration of cranberry juice by osmotic distillation process
Journal of Food Engineering, 2015Abstract An osmotic distillation (OD) system was implemented to concentrate cranberry juice at laboratory scale. The experimental setup allows the circulation of cranberry juice ( Vaccinium macrocarpon Ait .) and an osmotic agent with flow rates varying from 0.5 to 1.5 L min −1 at temperatures between 30 and 40 °C. The osmotic agent selected in this

Technoeconomic considerations in reverse osmotic concentration of seawater
Desalination, 1991Conditions of reverse osmotic concentration of seawater as the first step in the salt production are analysed. By separating out two third of the total water content of seawater the bulkiest phase in the salt production could be remarkably accelerated.

TRANSPIRATION AS INFLUENCED BY OSMOTIC CONCENTRATION AND CELL PERMEABILITY
American Journal of Botany, 1941IT is rather widely recognized that many plants which are resistant to drying conditions have a sap with a high osmotic concentration or a high colloid content or both. It is also recognized that a high content of solutes will reduce the vapor pressure of water, and that hydrophilic colloids have a high water holding capacity, and even in the ordinary "

Thermodynamic Modeling of the Osmotic Concentration Process
1994Mass transfer in osmotic concentration was modeled using thermodynamics of irreversible processes (TIP). The model assumed no leaching of soluble solids, but took into account shrinkage of the tissue. The model further assumed that the insoluble solids of the tissue did not have any effect on the physical and thermodynamic properties of the aqueous ...

Osmotic pressures of moderately concentrated polymer solutions
Journal of Polymer Science, 1957AbstractAn osmometer is described which is applicable to highly viscous concentrated polymer solutions. Results are presented for polyisobutylene (MW = 90,000) in cyclohexane at 30 and at 8°, and in benzene at 24.5° (the theta point) and at 50°. Concentrations ranging up to 20% (w/v) and 29%, respectively, were used.

Osmotic concentration kinetics and quality of carrot preserve
Food Research International, 1999The present study was undertaken to investigate the eAects of diAerent concentrations of sugar solution and sample to syrup ratio on the physico-chemical changes as well as sensory attributes of the product during the manufacture of carrot preserve. Results indicated that the boiled carrots should be pre-treated for 12 h in 40 Brix syrup followed by ...

Osmotic lysis of erythrocytes in relation to the zinc concentration of the medium
Archives of Dermatological Research, 1980The influence of various zinc concentrations on the osmotic resistance of erythrocytes was studied in six normal adults. Sodium chloride solutions ranging from 0.1% to 0.7% were prepared, each containing 0 microgram % zinc, 50 microgram % zinc, 100 microgram % zinc, 500 microgram %, and 1000 microgram % zinc.
