Abstract

<jats:p>The effectiveness of plastic packaging in protecting food is quite appreciable, but its non-biodegradable characteristic raises concerns about environmental impacts. This has drawn attention to the development of alternative materials for food packaging from bio-based polymers. Chitosan, a polysaccharide with biodegradable, biocompatible, and non-toxic properties, is widely used in the formulation of food films. The objective of this work was to create a biodegradable and sustainable chitosan-based film whose active and intelligent action is obtained from red cabbage anthocyanins and the addition of propolis. The edible film’s thickness and total polyphenol content were 61.0 ±0.1μm and 20.08 ±0.5 mgAG g-1, respectively. The content of phenolic compounds and the biodegradation showed significant results (p &lt;0.05), besides the good thermal stability to 200 °C and transparency. The proposed formulation developed an edible, biodegradable, and active (antioxidant) film with interesting heat-sealing resistance, moisture barrier and gas transfer, which contributes to increasing food shelf life.</jats:p>
