Figure 4

Microbial counts for (a) Listeria innocua and (b) Escherichia coli obtained after 6 days of incubation at 10 °C in TSA medium. Uncovered control plates (C), and covered plates with starch-polyester bilayer films: films without FA (S-P) and with FA (S-P-AF). Different superscript letters (a–c) indicate significant differences among formulations (p < 0.05). Different superscript numbers (1–3) indicate significant differences between the three storage times (p < 0.05). The numeric label on the S-P-AF bars gives the difference between the Log CFU of S-P-AF active film with respect to the S-P film.
