Utilization of edible coatings for extending the shelf life of fresh produce

Thesis Abstract

Abstract
The utilization of edible coatings for extending the shelf life of fresh produce has garnered significant attention in the field of food science and technology. This thesis explores the potential of edible coatings as a sustainable and effective solution to reduce food waste and enhance the quality and safety of fresh produce. The study begins with an introduction to the importance of extending the shelf life of fresh produce and the challenges associated with post-harvest losses. A comprehensive literature review is conducted to analyze existing research on edible coatings, their composition, application methods, and their impact on different types of fresh produce. The research methodology section outlines the experimental design, including the selection of edible coating ingredients, application techniques, and storage conditions for the fresh produce samples. The study investigates the effects of various edible coatings on the shelf life extension of fruits and vegetables through parameters such as moisture loss, color retention, microbial growth inhibition, and overall quality preservation. The findings from the experiments are discussed in detail in Chapter Four, highlighting the effectiveness of different edible coatings in prolonging the shelf life of fresh produce. The results indicate that edible coatings, when properly selected and applied, can significantly extend the shelf life of fresh produce by creating a protective barrier that reduces moisture loss, delays ripening processes, and inhibits microbial growth. The discussion delves into the mechanisms behind the protective properties of edible coatings and their potential applications in commercial food production. The study concludes with a summary of the key findings, implications for the food industry, and recommendations for future research in this area. Overall, this thesis contributes to the growing body of knowledge on the utilization of edible coatings for enhancing the quality and safety of fresh produce. By addressing the issue of post-harvest losses and food waste, edible coatings present a promising solution for improving the sustainability of the food supply chain and ensuring the availability of high-quality produce for consumers.
