Slow-release antibacterial film loaded with clove essential oil based on tapioca starch used for bread preservation.

ABSTRACT: White pollution is an increasingly serious concern. Consequently, the development of green degradable packaging materials has become a research focus. We incorporated different concentrations of clove essential oil (Ceo) (0 %, 0.5 %, 0.75 %, 1.0 %, and 1.25 %, w/w) into modified tapioca starch to formulate bacteriostatic compound films. The test results indicated that the barrier properties of the Ceo-series composite films surpassed those of the tapioca starch (TS) film. Specifically, the oxygen permeability of the 1.25 % Ceo film was 7.31 g/m²·s, the water vapor permeability decreased to 1.35 g/m²·s, and the oil permeability was reduced to 0.15 g mm m^-2 d^-1. In addition, the 1.25 % Ceo film exhibited inhibition zones of 4.23 ± 0.28 mm ag
