The persistence Postharvest losses of Tomato and other perishable fruits rise an urgenet need biodegradable and environmentally benign preservation methods. Polysaccharide-based edible coatings have shown great potential as alternatives to conventional synthetic methods for postharvest treatments due to their film-forming ability, biodegradability, biocompatibility, antimicrobial, and antioxidant carrier capabilities. This review examines the application of polysaccharide edible coatings as a sustainable preservation technique for tomatoes and other selected perishable fruits by considering their sources, functional and structural properties, in edible coating applications, focusing on their concentrations and preservation outcomes. Findings from published studies reveal that polysaccharide-based coatings reduce physiological weight loss, respiration rate, softening, ethylene production, colour change, and microbial damage, while enhancing nutritional constituents, hence extending the overall postharvest shelf life. Depending on the polymer concentration, molecular properties, fruit species, storage temperature, and coating formulation, it further demonstrated that, incorporating coatings with two or more polysaccharides, essential oils, plant extracts, and nanoparticles show improved preservative properties. The study suggests further studies on the development of low-cost, multifunctional, food-safe, polysaccharide-based coatings, especially those sourced from agricultural waste and other locally available resources. Such innovations could significantly contribute to sustainable postharvest control, food security, and environmentally benign food packaging systems.
