ANTIMICROBIAL AND PHYSICOCHEMICAL PROPERTIES OF METHYLCELLULOSE AND CHITOSAN FILMS CONTAINING A PRESERVATIVE
Abstract
The methylcellulose was mixed with chitosan as well as 4% of sodium benzoate or potassium sorbate to form a film. Investigations of the antimycotic activity of the film on Penicillium notatum and Rhodotorula rubra revealed that it possessed significant antifungal properties. At 25C, approximately 43–45% of the preservatives were released from the film to the glycerol-water mixture in the first 30 min. The maximum amount of preservative that could be released from the film at 25C was approximately 57–65%. At 4C, 38–39% of preservatives were released from the film within 30 min, and reached a maximum amount of 49% in approximately 6h. The FT-IR spectrum showed that the ionic interaction between -COO of preservatives and -NH3+ of chitosan existed in the film. However, the incorporation of preservatives did not affect the tensile strength and elongation property of the methylcellulose/chitosan film.

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.
