The study, conducted by Universiti Malaysia Pahang Al-Sultan Abdullah and International Islamic University Malaysia, explores the application of edible biopolymeric nanoparticles to address postharvest challenges in tropical fruits. These fruits, primarily grown in Southeast Asia, are renowned for their nutritional richness, unique taste, aroma, and visual appeal. However, nearly 50% of these fruits are wasted globally due to postharvest issues.
Edible biopolymeric nanoparticles, which are biodegradable, antimicrobial, antioxidant, non-toxic, and Generally Recognized As Safe (GRAS), offer a promising solution for preserving the freshness of these fruits. Typically prepared via ionic gelation, these nanoparticles can be used alone or in composite blends to enhance the physical and sensory qualities of fruits, inhibit microbial growth, and extend shelf life.
The study reviews the selection of materials for nanoparticle formulation, considering the fruit's epidermal properties and various application techniques such as spraying and layer-by-layer methods. It also discusses the advantages and disadvantages of these techniques, safety measures, legislation, current challenges, and industrial perspectives related to the use of edible coating films for fruits.
