In all osmotic solutions tested, WL and SG increased with
increasing concentrations of salt. In a solution concentration
of 50% sucrose/10% NaCl, the SG is lower than in a solution
concentration of 50% sucrose/5% NaCl, due to a boundary phase
formed on the product surface at higher solution concentrations,
decreasing the driving force between the solution and the
product. Similar results were observed by Kaymak-Ertekin and
Sultanoglu (2000), Sacchetti, Gianotti and Dalla Rosa (2001)
and Eren and Kaymak-Ertekin (2007), working with ternary
solutions.
