Quality of raw material
The variety and maturity of fruits and vegetables mainly control water loss and solid gain in the osmosis process.
Among different fruits variability is mainly related to the tissue compactness, initial insoluble and soluble solids
content, intercellular spaces and enzymatic activity of the fruit. The kinetic rate of solid gain did not depend
significantly on solute concentration or process temperature. Among different varieties of mango Dashehari and
Totapuri at ripe stage were found suitable for osmotic dehydration (Tiwari & Jalali, 2004).
