Edible Antimicrobial Films Based on Chitosan Matrix
Abstract
ABSTRACT: : Edible chitosan coatings showed anti‐ Listeria monocytogenes effect evaluated by numeration and epifluorescence methods, imparting a strong localized functional effect at the food surface by active packaging. The use of film‐forming solution in culture liquid medium showed a known flocculant phenomenon combined with bactericidal activity, keeping 20% of the initial microbial charge as viable cells in flocculant, which could develop subsequently. However, chitosan film showed 100% of L. monocytogenes inhibition for at least 8 d, completed by bactericidal activity measured by epifluorescence assays. A decrease in antibactericidal effect with time was obtained, most probably due to a decreasing availability of amino‐groups of chitosan. Latter results were validated on Emmental cheese samples using L. innocua as model strain because of its nonpathogenicity.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
