Average TBARS values at the beginning of storage were 3.7 mg malonaldehide/kg sample and did not
showed significant changes during the whole storage period (data not shown). The analyses of TBA were
limited by the microbial decay detected in non-coated samples at the end of storage.
Total viable and coliform counts of samples coated with chitosan-based films prepared with lactic acid
or acetic acid are shown in figure 2 and figure 3, respectively.
