Changes in pH of the osmotic solution with time were presented in figure 2b. For sugar solution, pH showed a slight decrease from 5.4 to 5.1 while in sugar/salt solution it decreased from 5.1 to 4.9. The pH fluctuated with osmotic dehydration time but the changes were not
significant, and these values have advantage of inhibiting microbial growth [17]. Equations were fitted to establish correlation relationships between pH and electrical conductivity of the medium but the degree of fit were low (0.042
