Osmotic and convective hot air drying of sweet gourd
Food Science and Biotechnology, 2022Kinetics of osmotic dehydration (OD) and insights into the effect of salt concentration (5%, 10%, 15%, 20%), drying temperature (50 ∘C, 60 ∘C, 70 ∘C), and sample thickness (4 mm, 6 mm, 8 mm) on the drying kinetics of sweet gourd of two varieties (SGV-1 and SGV-2) were investigated based on the Fick's second law of diffusion model.

Osmotic Dehydration Pretreatment in Drying of Fruits and Vegetables
Drying Technology, 2003Abstract Several vegetables and fruits, apple, ginger, carrot, and pumpkin were dehydrated under various osmotic conditions using sucrose and salt as the permeating agents. The dehydrated materials were then dried. The influence of solute concentration, process temperature and the type of solute on osmotic dehydration and further thermal drying were ...

Microwave Drying of Osmotically Dehydrated Blueberries
Journal of Microwave Power and Electromagnetic Energy, 1998The drying rates, rehydration ratios, color, texture and sensory evaluations of blueberries that were pretreated with ethyl oleate and sodium hydroxide, osmotically dehydrated in sucrose and dried in various regimes were compared. The drying regimes were: convection (35 °C or 45 °C at 2 m s-1); microwave-assisted convection (0.1 or 0.2 W g-1 incident ...

COMBINED OSMOTIC AND MICROWAVE DRYING OF STRAWBERRIES
Drying Technology, 1999ABSTRACT Strawberries pretreated with 2% ethyl oleate and 0.5% NaOH were osmotically dehydrated and their osmotic dehydration rate is compared with untreated berries. It was found that treated berries dehydrated belter compared to untreated berries. Osmotically dehydrated berries were convective and microwave dried at different power levels and results

Osmotic Concentration – Drying of Mango Slices
Drying Technology, 1995ABSTRACT The effect of initial water activity (aw) of mango slices obtained by osmotic concentration pre-treatments with sucrose syrups on their air-drying behavior at 50, 60 and 70°C were evaluated calculating the apparent diffusion coefficients with second Fick's law.

Osmotic Dehydration of Peas and its Effect on Drying
1994Peas have been partially dehydrated by immersion in pure sucrose and sodiumcitrate solutions or sucrose/sodiumcitrate mixed solutions prior to air drying. The influence of concentration and composition of osmosis solutions, immersion time and agitation on the mass transport data described in terms of water loss and solid gain and on water activity data

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.

Osmotic tablet coatings: Drying stress, mechanical properties and microstructure
International Journal of Pharmaceutics, 2022The coatings in osmotic tablets play a critical role in controlling the release of active pharmaceutical ingredient. Coatings are formed by spraying dilute polymer solution onto the tablet surface. During drying, the films develop shrinkage stress, which can cause cracking.
