Chicken drumsticks packaged with active bags had lower
(P < 0.05) APC than the sample packed with control bags. At the 6th
day of storage, APCs of samples packaged with nisin or chitosan
bags were not statistically different (P > 0.05), but were lower
(P < 0.05) APC than those of other samples. Similar resultswere also
found by Siragusa, Cutter, and Willett (1999) and Park, Marsh, and
Dawson (2010). Siragusa et al. (1999) used nisin incorporated low
density polyethylene (LDPE) film for controlling food spoilage and
enhancing product safety since nisin, a bacteriocin, inhibits Grampositive
food borne pathogens and spoilage microorganisms. Park
et al. (2010) observed that chitosan could be released from LDPE
films to inhibit bacterial growth and that higher chitosan concentrations
(1.4%) inhibited both gram positive and gram negative
bacteria.
