New film for biodegradable food packaging
Xyloglucan from tamarind seed kernel powder and chitosan were prepared using acetic acid as an oxidising agent to form a xyloglucan-chitosan film.
During the study the properties of xyloglucan-chitosan films with different loading ratios of xyloglucan were evaluated by using various analytical tools. The covalent bonds formed by the oxidised xyloglucan and chitosan were confirmed by FTIR analysis. Morphological analysis using SEM indicated the formation of a conventional covalent bond in the xyloglucan-chitosan film.
Antimicrobial activity
The water vapor transmission rate in the xyloglucan-chitosan film was reduced significantly with increasing xyloglucan ratio. Conversely, the increase in the xyloglucan ratio improved the film’s mechanical properties. Furthermore, due to the antimicrobial activity of chitosan, the xyloglucan-chitosan film exhibits intense antimicrobial activity. Therefore, the xyloglucan-chitosan film demonstrated good properties for biodegradable food packaging.
