Chitosan-metal and metal oxide nanocomposites for active and intelligent food packaging; a comprehensive review of emerging trends and associated challenges

Carbohydrate Polymers, Journal Year: 2025, Volume and Issue: 357, P. 123459 - 123459

Published: March 3, 2025

In recent years, significant advancements in biopolymer-based packaging have emerged as a response to the environmental challenges posed by traditional petroleum-based materials. The drive for sustainable, renewable, and degradable alternatives fossil-based components industry has led an increased focus on chitosan, second most abundant biopolymer after cellulose. Chitosan offers intrinsic properties such biodegradability, biocompatibility, antimicrobial activity, excellent barrier film-forming capabilities, positioning it ideal candidate food applications. However, limitations including inferior mechanical, thermal, properties, brittleness compared conventional plastics limiting its widespread adoption industry. been extensively utilized various forms, particularly nanocomposites incorporating metal nanoparticles, leading chitosan-based nanocomposite films/coatings that synergistically combine advantageous of both chitosan nanoparticles. Through in-depth analysis current research (primarily last 5 years), this review delves into physicochemical, sensing, innovative material. This will provide insights potential toxicity impact nanoparticle migration, well prospects associated with chitosan-metal/metal oxide films development sustainable solutions.

Effects of biodegradation of starch-nanocellulose films incorporated with black tea extract on soil quality

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Aug. 13, 2024

Abstract This study aimed to investigate the biodegradation behaviour of starch/nanocellulose/black tea extract (SNBTE) films in a 30-day soil burial test. The SNBTE were prepared by mixing commercial starch, nanocellulose (2, 4, and 6%), an aqueous solution black simple casting process. chemical morphological properties before after characterized using following analytical techniques such as field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDX), fourier transform infrared (FTIR). changes composition, namely pH, electrical conductivity (EC), moisture content, water holding capacity (WHC), respiration, total nitrogen, weight mean diameter (MDW), geometric (GMD), result process, also estimated. results showed that exhibited considerable biodegradability (35–67%) within 30 days while increasing nutrients. addition reduced rate due its polyphenol which likely resulted reduction microbial activity. (2–6% starch) increased tensile strength, but decreased elongation at break films. These suggest starch are not only biodegradable under conditions positively contribute health, highlighting their potential environmentally friendly alternative traditional plastic packaging industry.
