Concentration of pineapple juice by osmotic evaporation [PDF]

Journal of Food Engineering, 2008
Abstract The aim of this work was to evaluate the process of osmotic evaporation to concentrate pineapple juice. In order to study the effect of pulp content on the performance, clarified and single strength pineapple juices were successively concentrated up to 57 g 100 g−1 total soluble solids (TSS).

Osmotic concentration and dilution of the urine

The American Journal of Medicine, 1964
I T is now generally accepted that urine is osmotically concentrated in the mammalian kidney through the operation of the countercurrent mechanism in the renal medulla. Although the over-all course of events seems clear, i.e., initial concentration in the descending, and dilution in the ascending limb of the loop of Henle, and final concentration in ...

Osmotic pressures of moderately concentrated polydimethylsiloxane solutions

Journal of Polymer Science Part C: Polymer Symposia, 1968
AbstractOsmotic pressures of polydimethylsiloxane in chlorobenzene, toluene, and cyclohexane were measured over a wide range of concentration (0 < v2 < 0.25). A peculiar behavior of an apparent second virial coefficient, observed by others, was not observed in a transition region (c ≈︁ 0.05).

Osmotic pressures of moderately concentrated polymer solutions

Journal of Polymer Science, 1957
AbstractAn 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.

Pinneapple juice concentrated by osmotic evaporation

2002
Pasteurized pineapple juice was concentrated by osmotic evaporation to produce a 51°Brix concentrate that was reconstituted to single strength juice for evaluation. Headspace gas chromatography (HSGC) showed that the concentrate retained an average of 62% of the volatile components present in the initial juice.

Thermodynamic Modeling of the Osmotic Concentration Process

1994
Mass 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 Pressure of Moderately Concentrated Polymer Solutions

The Journal of Chemical Physics, 1960
By two methods, a linearization and a variational principle, the Born-Green-Kirkwood equation for the radial distribution function is solved approximately and the osmotic pressure of chain polymer solutions computed at arbitrary concentration. The gaussian intermolecular potential energy of Flory and Krigbaum is used, and this restricts the range of ...
