Abstract: A composite antimicrobial coating made by carboxymethylcellulose (CMC) and gelatin was used for preservation of bacon. Using water vapor permeability, transparency and thickness as indicators, the formula of antimicrobial film was optimized. Meanwhile, the composite antimicrobial coating was also added potassium sorbate during preparation process. The results showed the best composite antimicrobial coating was achieved by adding 0.4% glycerol and 0.08% potassium sorbate to 10 g/L film-forming solution composed of carboxymethylcellulose and gelatin at a ratio of 1:2. Bacon dipped in the composite antimicrobial film-forming solution revealed a slow decay rate and prolonged storage period.

Key words: bacon, edible film, antimicrobial
