Summary

This study investigated the effect of nisin added to zein film coatings (Z) coated onto ready-to-eat chicken against L. monocytogenes. L. monocytogenes inoculated chicken samples were dipped into Z dissolved in propylene glycol (ZP) or ethanol (ZE), with and without added nisin (N) and/or 1% calcium propionate (CP) then stored at 4 or 8 °C for 24 d. After 16 d at 4 °C the growth of L. monocytogenes was suppressed by 4.5 to 5 log CFU/g and at 2.7 log CFU/g counts were maintained at a non-detectable level from day 0 to day 24 with ZEN, ZPNCP, or ZENCP. Zein film coatings with nisin can prevent the growth of L. monocytogenes on ready-to-eat chicken.
