Thesis Abstract

Abstract
This thesis investigates the impact of various food processing methods on the nutritional content of fruits and vegetables. The study aims to explore how different processing techniques, such as cooking, freezing, drying, and canning, affect the nutrient levels in these food products. The research is motivated by the increasing consumption of processed foods globally and the potential implications on public health and nutrition. A comprehensive review of the literature on food processing and nutrient retention provides a foundational understanding for this study. Chapter 1 provides an introduction to the research topic, outlining the background, problem statement, objectives, limitations, scope, significance, structure of the thesis, and key definitions. The literature review in Chapter 2 examines existing studies on the impact of food processing methods on the nutritional content of fruits and vegetables. Ten key themes emerge from the literature, including the effects of heat processing, storage methods, and packaging on nutrient retention. Chapter 3 details the research methodology employed in this study, including the selection of fruits and vegetables, processing techniques, and nutrient analysis methods. The methodology section also describes the experimental design and data collection procedures. Findings from the research are presented and discussed in Chapter 4, highlighting the changes in nutrient levels following various processing methods. The results reveal significant variations in nutrient content based on the processing method employed. For example, vitamin C levels may decrease with heat processing, while certain minerals may be better retained through freezing. The discussion delves into the implications of these findings for consumer choices and public health recommendations. Chapter 4 also includes comparisons with previous studies and identifies gaps in the existing research. Chapter 5 concludes the thesis by summarizing the key findings and implications of the study. Recommendations for future research and practical applications are provided based on the outcomes of this investigation. Overall, this thesis contributes valuable insights into the complex relationship between food processing methods and the nutritional quality of fruits and vegetables, offering guidance for consumers, food manufacturers, and policymakers in promoting healthier dietary practices.
