Biodegradable packaging materials generally comprise a solution to the environmental problem caused by consecutive use of conventional (petroleum-based materials) even though these have high cost. The monomers resulting from slow degradation petroleum-based contribute pollution environment. distinguished biodegradability and biocompatibility can successfully replace aforementioned thus solve problems their or deposition. Although several biodegradable present defective properties, mainly mechanical barrier are reduced eliminated addition various improving additives blending them with other biopolymers. Various natural preservatives such as essential oils phytochemical extracts also be incorporated into biopolymer network increase its efficacy. This treatment is particularly beneficial since it contributes increasing shelf life storability packaged foods fruits, vegetables, dairy products, meat poultry, fish. For all above reasons, preferences consumers critical thinking/decisions food product manufacturing industries in favor potential more more. In this context, review article addresses most recently used for preservation presenting sources, advantages, limitations, future perspectives.

Recent Advances in Poly(vinyl alcohol)-Based Hydrogels

Polymers, Journal Year: 2024, Volume and Issue: 16(14), P. 2021 - 2021

Published: July 15, 2024

Poly(vinyl alcohol) (PVA) is a versatile synthetic polymer, used for the design of hydrogels, porous membranes and films. Its solubility in water, film- hydrogel-forming capabilities, non-toxicity, crystallinity excellent mechanical properties, chemical inertness stability towards biological fluids, superior oxygen gas barrier good printability availability (relatively low production cost) are main aspects that make PVA suitable variety applications, from biomedical pharmaceutical uses to sensing devices, packaging materials or wastewater treatment. However, pure present limited flexibility poor biocompatibility biodegradability, which restrict its use alone various applications. mixed with other polymers biomolecules (polysaccharides, proteins, peptides, amino acids etc.), as well inorganic/organic compounds, generates wide PVA’s shortcomings considerably improved, new functionalities obtained. Also, transformation brings features opens door unexpected uses. The review focused on recent advances PVA-based hydrogels.

Resveratrol-derived carbon dots integrated into gelatin/chitosan multifunctional films for intelligent packaging

Food Chemistry X, Journal Year: 2025, Volume and Issue: 25, P. 102182 - 102182

Published: Jan. 1, 2025

In this study, multifunctional Resveratrol-derived carbon dots (Res-CDs) were prepared using a hydrothermal method. Res-CDs exhibited good free-radical scavenging activities, attributed to abundant surface hydroxyl groups, and effectively inhibited Staphylococcus aureus Escherichia coli growth at concentration of 2 mg/mL. Composite films by combining with gelatin/chitosan. As well as excellent mechanical properties, the smooth surfaces, thermal stability, antioxidant, ultraviolet-shielding, antibacterial, pH-responsive properties. Furthermore, cell viability measurements showed that safe. When applied keeping pork fresh, gelatin/chitosan/Res-CDs film significantly reduced total viable bacterial count on prevented discoloration. Additionally, pH, volatile basic nitrogen, weight loss confirmed preservative effects pork. This work provides new approach for synthesizing bionanocomposite applicability in food industry.

Recent Advances in Functional Cellulose-based Films with Antimicrobial and Antioxidant Properties for Food Packaging

Journal of Agricultural and Food Chemistry, Journal Year: 2023, Volume and Issue: 71(44), P. 16469 - 16487

Published: Oct. 25, 2023

The packaging of food plays a crucial role in preservation worldwide. However, traditional systems are passive layers with weak efficiency protecting the quality. Therefore, packaged foods gradually spoiled due to oxidation and growth microorganisms. Additionally, most commercial films made petroleum-based materials which raise environmental concerns. Accordingly, development eco-friendly natural-derived active has increased attention scientists. Cellulose as abundant polysaccharide on earth high biocompatibility, no toxicity, biodegradability extensively been applied for fabrication films. neat cellulose-based lack antioxidant antimicrobial activities. performance. Active have developed by incorporating antioxidants agents into In this review, we explored latest research antimicrobial/antioxidant natural extracts, polyphenols, nanoparticles, microparticles film formulations. We categorized these types two main groups: (i) blend obtained mixing solutions cellulose other soluble such extracts polyphenols; (ii) composite fabricated dispersing nano- or microfillers solution. effect additives properties explained. changes hydrophilicity, water evaporation rate, mechanical also briefly addressed.
