the physicochemical, mechanical, optical and structural properties based on different amylose content
starch–chitosan films with the addition of hydrophilic glycerol and hydrophobic perilla oil were inves-
tigated, and the effects of the starch–chitosan coating on the physicochemical and microbial properties
of Mongolian cheese were evaluated. The films were formed by casting method. Results showed that the
incorporation of perilla oil resulted in a decrease in moisture content, solubility and mechanical properties
and an increase in total color difference ( E*). High water vapor permeability (WVP), good transparency
and low solubility were observed with the addition of glycerol. Meanwhile, the film based on mung bean
starch–chitosan (MSC) exhibited higher moisture content, WVP values, E* and less transparency than
that based on water chestnut starch–chitosan (WSC). The morphology of films was also different based
on MSC/WSC. The shelf life extension of Mongolian cheese was evaluated at 8 ◦ C. The results showed that
the cheese coated by WSC film containing perilla oil presented better treatment performance in terms of
microbial growth delay, weight loss and shelf life length.
