The reduction of weight (WL %), loss of water
(WR %) and solute (sugar) gain (SG %) were observed
in osmotic dehydration of mango slices. The
phenomena of mass transfer were affected by
temperature and process time. Temperature and process
time were different from the range of 40 to 120 minutes
and 30 to 50°C respectively (Gabriela et al., 2004).
Osmotic dehydration process was done to increase the
final quality of product. This pretreatment was done on
banana and tomato rings, which helped to study of
kinetics of osmotic dehydration, color properties and
organoleptic evaluations. The results showed that much
reduction of weight when 100% sucrose used as
osmotic agent in banana. The tomato showed the
highest values when 30% NaCl and sucrose: salt (1:
1.5) were used. The osmotic dehydration of tomato
showed the lower chroma (C*) and redness values (a*)
during osmotic dehydration (Ali et al., 2010
