Impact of fish myofibrillar protein and apple pectin–konjac glucomannan on the physical, thermal, and micro-structural properties of biodegradable blend film
Despite its title referencing biodegradable film and biopolymers, this paper studies the physical and thermal properties of food packaging films made from fish protein, apple pectin, and konjac glucomannan — not microplastic pollution. It examines how varying protein concentration affects film mechanical performance and UV-blocking ability, and is not directly relevant to microplastics or human health.
Preparation and investigation of the structural and mechanical properties of biodegradable gelatin- based films
Researchers prepared biodegradable gelatin-based films with carboxymethylcellulose (CMC) additives for potential use as food packaging and drug carriers, then characterized their structural, mechanical, and barrier properties using SEM, roughness measurement, and IR spectroscopy. CMC addition decreased film strength and elastic modulus while maximizing deformation at a CMC/gelatin mass ratio of 0.7, with H-bond and electrostatic interactions between gelatin proteins and polysaccharide macromolecules stabilizing the film structure.
Current trends in biopolymers for food packaging: a review
This review covers the latest developments in biopolymer-based food packaging, including biodegradable films, edible coatings, and active or smart packaging systems.
