Abstract

Curcumin is a phenolic compound derived from turmeric roots (Curcuma longa L.). This research studied the effects of curcumin extract on the properties of chitosan films. The film characteristics measured included mechanical properties, visual aspects, color parameters, light transmission, moisture content, water solubility, water vapor permeability, infrared spectroscopy, and antioxidant activity. The results suggest that adding curcumin to chitosan-based films increases yellowness and light barriers. Infrared spectroscopy analysis showed interactions between the phenolic compounds of the extract and the chitosan, which may have improved the mechanical properties and reduced the moisture content, water solubility, and water vapor permeability of the films. The antioxidant activity of the films increased with increasing concentrations of the curcumin extract. This study shows the potential benefits of incorporating curcumin extract into chitosan films used as active packaging.

Highlights

At present, many people are interested in active biopolymer packaging due to its excellent biodegradability, edibility, and potential applications [1]
The aim of this research was to use curcumin extract to prepare chitosan films and to study the effects that incorporating this extract may have on the physical properties, mechanical properties, and antioxidant activity of chitosan-based films
These results clearly indicate that curcumin has an effective and powerful antioxidant activity [25] when higher concentrations are added to the curcumin extract [8]

Summary

Introduction

Many people are interested in active biopolymer packaging due to its excellent biodegradability, edibility, and potential applications [1]. Chitosan is a linear polysaccharide of randomly distributed β-(1–4)-linked D-glucosamine, the deacetylated product of chitin [2]. It is nontoxic, biodegradable, biocompatible, and has film-forming abilities [3]. Chitosan films have the potential to be employed for packaging, as edible packaging This is due to their excellent oxygen and carbon dioxide barrier properties and interesting antimicrobial properties [6]. Chitosan is an excellent edible film component due to its transparent film-forming capacity and good mechanical properties, with applications for a variety of packaging needs [7]
