In order to clearly compare the effect of 2% chitosan coating on the weight reduction, all experimental data in
each sample was linearised to evaluate the rate of weight loss indicated by the slope. The following equations
represented the time-related change in weight loss for control (C0) and coated samples with chitosan composition of
2% w/w combined with two different DD of chitosan 70%, 80% (C3, C3*) and TEA emulsifier addition (CT3,
CT3*). The linear regression seemed fit to all experimental data in each sample indicated by a relatively good
correlation coefficient
