Food packaging plays a crucial role in preserving freshness and prolonging shelf life worldwide. However, traditional primarily acts as passive barrier, providing limited protection against spoilage. Packaged food often deteriorates due to oxidation microbial growth, reducing its quality over time. Moreover, the majority of commercial relies on petroleum-derived polymers, which add environmental pollution since they are not biodegradable. Growing concerns sustainability have driven research into eco-friendly alternatives, particularly natural-based active solutions. Among various biopolymers, cellulose is most abundant natural polysaccharide has gained attention for biodegradability, non-toxicity, compatibility with biological systems. These qualities make it strong candidate developing sustainable materials. pure films limitations, lack antimicrobial antioxidant properties, their ability actively preserve food. To tackle this issue, researchers created cellulose-based by integrating bioactive agents properties. Recent innovations emphasize improving these through incorporation extracts, polyphenols, nanoparticles, microparticles. enhancements strengthen protective functions, leading more effective preservation. The generally classified two types: (i) blend films, where soluble substances like plant extracts polyphenols incorporated solution, (ii) composite embed nano- or micro-sized fillers within structure. addition functional components enhances efficiency while also affecting properties water resistance, vapor permeability, mechanical strength. continuous progress highlights potential viable alternative conventional innovative only extend but contribute reliance synthetic polymers. This review deals development biopolymer towards packaging.

Sustainability in the Development of Natural Pigment-Based Colour Masterbatches and Their Application in Biopolymers

Polymers, Journal Year: 2024, Volume and Issue: 16(15), P. 2116 - 2116

Published: July 25, 2024

This article is focused on the development and characterization of a series biodegradable eco-friendly colour masterbatches (MBs), based natural pigments polylactic acid (PLA) polybutylene succinate (PBS). Four commercial were used, spirulina, curcumin, beetroot chlorophyllin, to develop using twin-screw extruder. The pigment-based MBs added at 2, 4 6 wt%, as additives study effect properties injected parts (PLA PBS). samples characterized in terms their mechanical (tensile Charpy impact tests) visual (according CieLab). In addition, ageing coloured material was followed by colorimetric analysis after its exposure under Xenon lamp. results showed that addition different percentages (2–6 wt%) did not significantly change materials with respect as-received ones. A noticeable difference observed first 50 h artificial light exposure. Regarding environmental concerns, carbon footprint electricity consumption during extrusion pelletizing lower.

An Intelligent Indicator Film Based on Food Derived Materials for Real-Time Visual Monitoring of Salmon Freshness

Journal of Aquatic Food Product Technology, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 13

Published: Nov. 6, 2024

Determining the freshness of aquatic products during food processing, transportation, and preservation is critical for ensuring safety quality. In this study, we developed intelligent indicator films sensitive to nitrogen compounds using sodium alginate, glycerol, natural pigments. These exhibited excellent indicating performance in monitoring salmon, including total volatile basic (TVB-N), thiobarbituric acid-reactive substances (TBARS), pH levels. Additionally, exhibit both thermal stability good biocompatibility. This finding paves way developing safe effective indicators with potential uses packaging, related industries.
