Abstract
Moisture sorption characteristics of microbial polysaccharide (Ps.C101) from Pseudomonas
caryophilli and polyvinyl alcohol (PVA) blends have been carried out at 27�C for water activity
from 0.1 to 0.9. The sorption data was used to fit six different sorption isotherm models
proposed in literature. The model constants were determined by linear fitting of the sorption
equations. The ranges of applicability of water activity for isotherm models reported in this
paper lie in between 0.1 and 0.4 for Brunaur–Emmet–Teller (BET) model (monolayer), and in
between 0.2 and 0.9 for other models. The value of the coefficient of determination
(R2 = 0.97 ± 0.02) confirms the applicability of the equations studied.
