(Fig. 2A). Hence, the constant presence of CA in films during storage
(Table 4) modified the browning kinetics, which slowed down the
browning development, after the initial period of film storage. It
was herein found that the CA content of films did not change during
storage (Table 4), while browning was developed in films according
to a zero- and first-order combined kinetic, subsequently to the AA
loss. Hence, as the CA content in films did not change (Table 4) it
can then be suggested that CA did not react during the AA degradation
and browning development. However, CA modified the kinetic
order of the browning reaction, which means that the
mechanism of this reaction was changed.
