Transfer of mass during osmotic dehydration
inclined by temperature, size and geometry,
concentration of osmotic solution, material to solution
ratio, agitation, degree of solution, and methods of predrying.
Temperature was much important factor which
involved in breaking the integrity of plant material and
membrane; for example plasma membrane started to
undergo irreversible damage at 50°C (Thebud and
Santarius, 1982). With increasing the level of agitation
then was increasing the rate of dehydration. The
sufficient level of agitation ensured the minimization of
mass transfer affected on liquid side (Rastogi et al.,
2002). When the time spent over, then membrane did
not provide barrier for the solute, which penetrated to
the cell (Mauro et al., 2002).
