Abstract
Studies on the moisture sorption characteristics
of poly(vinyl alcohol)/starch blends for water activity
(aw) values of 0.1– 0.9 were performed at 27°C. The equilibrium
moisture content at different aw values was used to fit
different sorption isotherm models proposed in the literature.
The ranges of aw applicable for the different sorption
isotherms were reported. The model constants of the sorption
equations were determined by linear fitting. The value
of the coefficient of determination (0.98 � 0.01) confirmed
the goodness of fit of the equations studied.
