Chitosan/corn starch blend films with extract from Brassica oleraceae (red cabbage) as a visual indicator of fish deterioration
Open accessAbstract
Chitosan and Starch are polymers that can be obtained from renewable sources, with good film-forming properties and many applications in food industry, such as active and smart-packaging, which can monitor and inform consumers about food conditions in real-time. Hence, we report here a system for pH monitoring based on Chitosan, Corn Starch and red cabbage extract, all inexpensively obtained from renewable sources. The system was produced from medium molecular weight Chitosan, Corn–Starch and phytochemical extract from Brassica oleracea var. capitata (Red Cabbage). TG-DSC, FT-IR, Water Vapour Transmission Rate, as well as light microscopy were used to characterize the system. The colour variation after activation in different pH range was measured with the CIELab methodology. In order to validate the use of this system as a fish spoilage detection sensor, application tests were conducted with fish fillets. The results show that the system has good optical and morphological properties and is very sensitive to pH variations. During the application test, the system visually indicated pH changes. Thus, the system shows a clear response to pH variation of the samples. Therefore, it has potential to be used as a visual indicator of the storage and consumption conditions of food.

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.
