Investigation of the potential use of edible coatings to extend the shelf life of fresh produce.

Thesis Abstract

Abstract
This thesis investigates the potential use of edible coatings to extend the shelf life of fresh produce. The study aims to address the pressing issue of food waste by exploring innovative methods to enhance the preservation of perishable fruits and vegetables. The research is motivated by the increasing demand for sustainable food preservation techniques that can reduce post-harvest losses and improve food security. The study begins with a comprehensive review of existing literature on edible coatings, their composition, application methods, and impact on food quality and shelf life. Various types of edible coatings and their effectiveness in extending the shelf life of fresh produce are critically analyzed to provide a solid theoretical foundation for the research. The methodology chapter outlines the experimental design and procedures employed to evaluate the efficacy of different edible coatings in extending the shelf life of selected fruits and vegetables. Parameters such as coating composition, application techniques, storage conditions, and quality attributes of coated produce are systematically analyzed to determine the optimal coating formulation for maximum shelf life extension. The findings chapter presents the results of the experiments conducted to assess the effectiveness of edible coatings in prolonging the shelf life of fresh produce. Data on changes in physical, chemical, and microbiological properties of coated fruits and vegetables during storage are meticulously analyzed to elucidate the impact of edible coatings on food preservation. The discussion chapter critically evaluates the implications of the research findings, compares them with existing literature, and highlights the potential benefits of adopting edible coatings as a sustainable solution to reduce food waste and enhance food security. The limitations of the study are acknowledged, and recommendations for future research in this area are provided. In conclusion, this thesis underscores the significant potential of edible coatings in extending the shelf life of fresh produce and offers valuable insights into the application of this technology in the food industry. The study contributes to the growing body of knowledge on sustainable food preservation methods and underscores the importance of leveraging innovative solutions to address global food security challenges.
