Thesis Abstract

Abstract
This thesis investigates the effects of various food processing methods on the nutritional quality of fruits and vegetables. The study aims to explore how different processing techniques, such as blanching, freezing, canning, and drying, impact the nutritional content of these perishable food items. The research is motivated by the growing concern for maintaining the nutritional value of processed foods to ensure consumer health and well-being. The introduction provides an overview of the importance of fruits and vegetables in the human diet and the role of processing in extending their shelf life. The background of the study delves into the historical development of food processing methods and their impact on food quality. The problem statement highlights the need to understand how different processing techniques affect the nutritional composition of fruits and vegetables. The objectives of the study are to evaluate the nutritional changes in fruits and vegetables resulting from various processing methods, identify the key factors influencing these changes, and assess the overall impact on consumer health. The limitations of the study are acknowledged, including constraints related to sample size, processing conditions, and analytical techniques. The scope of the study encompasses a comprehensive analysis of the nutritional quality of a variety of fruits and vegetables subjected to different processing methods. The significance of the study lies in its potential to inform food processors, policymakers, and consumers about the best practices for preserving the nutritional value of processed foods. The literature review in Chapter Two presents a synthesis of existing research on the effects of food processing on the nutritional content of fruits and vegetables. It covers topics such as nutrient degradation, bioavailability, and the influence of processing parameters on nutritional quality. Chapter Three outlines the research methodology, including the selection of fruits and vegetables, processing techniques, sample preparation, and analytical methods. The study design incorporates both qualitative and quantitative analyses to assess changes in key nutrients such as vitamins, minerals, and antioxidants. Chapter Four presents a detailed discussion of the findings, highlighting the impact of different processing methods on the nutritional profile of fruits and vegetables. The results reveal variations in nutrient retention and degradation across various processing techniques, shedding light on the factors contributing to these changes. In conclusion, Chapter Five summarizes the key findings of the study and discusses their implications for food processing practices and consumer health. The thesis contributes to the body of knowledge on food science and technology by providing insights into the effects of processing methods on the nutritional quality of fruits and vegetables, ultimately promoting informed decision-making in the food industry.
