Bacteriocins, naturally derived antimicrobial peptides, are considered promising alternatives to traditional preservatives and antibiotics, particularly in food and medical applications. Despite extensive research on various bacteriocins, cyclic varieties remain understudied. This study introduces Gassericin GA-3.

The aim of the present research was to evaluate the effect of Urtica dioica L. (nettle) essential oil (in the forms of Pickering nanoemulsion (NEO) and free (EO)) on microbial, chemical and sensory changes of pizza cheese stored at 4 °C for 12 days. For this purpose, Escherichia coli and Listeria monocytogenes were inoculated into pizza cheese.

Polysaccharides represent the most abundant biopolymers in agri-food wastes and thus are the most studied polymers to produce biodegradable films for use in packaging. Starch is among the major polysaccharides extracted from food and agricultural waste that have been used as precursor material for film production. Therefore, the present study aimed at producing an active film with antimicrobial properties using starch extracted from cassava waste and oil extracted from cloves.

The immobilisation of essential oil components (EOCs) on food-grade supports is a promising strategy for preserving liquid foods without the drawbacks of direct EOC addition such as poor solubility, high volatility, and sensory alterations. This study presents a novel method for covalently immobilising EOCs, specifically thymol and carvacrol, on SiO particles (5-15 µm) using the Mannich reaction. This approach simplifies conventional covalent immobilisation techniques by reducing the steps and reagents while maintaining antimicrobial efficacy and preventing compound migration.

is a Gram-positive bacterium causing listeriosis, a severe infection responsible for significant morbidity and mortality globally. Its persistence on food processing surfaces via biofilm formation presents a major challenge, as conventional sanitizers and antimicrobials exhibit limited efficacy against biofilm-embedded cells. This study investigates a novel approach combining an engineered polysaccharide-degrading enzyme (CAase) with a bacteriocin (thermophilin 110) produced by .
