"Natural Antimicrobials and Antioxidants in Shelf-Stable Low-Moisture RTE Foods": A Review of Synergistic Preservation Strategies
Abstract: Shelf-stable, low-moisture foods (LMFs) and ready-to-eat (RTE) foods are increasingly in demand due to their extended shelf life, convenience, and minimal storage requirements. However, despite their low water activity, LMFs remain susceptible to quality degradation and microbial contamination over time, particularly by xerophilic and osmophilic microorganisms. This review explores the role of natural antimicrobials and antioxidants as effective preservation agents in LMFs, emphasising their synergistic interactions when used in combination. Natural compounds such as essential oils, plant extracts (e.g., rosemary, green tea), organic acids, and bacteriocins offer broad-spectrum antimicrobial activity. In contrast, phenolic compounds and tocopherols serve as potent antioxidants to retard lipid oxidation and preserve sensory qualities. The integration of these bioactive agents into edible films, coatings, or active packaging systems is also discussed, with a focus on compatibility with biodegradable matrices. Furthermore, the review assesses factors that influence the efficacy of these compounds, including concentration, food matrix interactions, and environmental conditions. By highlighting synergistic combinations and multifunctional effects, this paper provides insight into designing holistic, clean-label preservation strategies for LMFs, aligning with consumer demand for natural, sustainable, and safe food products.
