Project Abstract

Abstract
The increasing demand for fresh produce has led to the exploration of innovative preservation methods to extend their shelf life while maintaining quality and safety. This research project focuses on investigating the use of edible coating as a preservation method for fresh produce. Edible coatings are thin layers of edible materials applied to the surface of fruits and vegetables to create a barrier against moisture loss, gas exchange, and microbial growth. The objective of this study is to evaluate the effectiveness of edible coatings in prolonging the shelf life of fresh produce and maintaining its sensory attributes. The research begins with a comprehensive literature review that examines previous studies on edible coatings, their composition, application methods, and impact on the quality and shelf life of fresh produce. The review also explores the mechanisms through which edible coatings function, such as gas permeability, moisture retention, and antimicrobial properties. The methodology chapter outlines the experimental design, including the selection of fresh produce samples, preparation of edible coatings, application methods, and storage conditions. The study incorporates various analytical techniques to assess the physical, chemical, and microbiological characteristics of the coated produce throughout the storage period. Parameters such as weight loss, firmness, color changes, sugar content, acidity, microbial growth, and sensory attributes are measured to evaluate the efficacy of edible coatings. The results chapter presents a detailed analysis of the findings, including the effects of different types of edible coatings on the quality and shelf life of fresh produce. The discussion explores the relationships between coating composition, application methods, storage conditions, and the preservation outcomes. The implications of the results are discussed in the context of improving postharvest handling practices and reducing food waste in the supply chain. In conclusion, this research project provides valuable insights into the use of edible coatings as a sustainable preservation method for fresh produce. The study contributes to the growing body of knowledge on postharvest technologies and offers practical recommendations for industry stakeholders to enhance the quality and shelf life of perishable foods. Further research opportunities are identified to optimize the application of edible coatings and address challenges related to scalability, cost-effectiveness, and consumer acceptance.
