Project Abstract

Abstract
Lipid oxidation is a major concern in the food industry, leading to quality deterioration and health risks in food products. Natural antioxidants have garnered significant attention as potential alternatives to synthetic antioxidants due to their perceived safety and consumer preferences. This research project aims to investigate the effectiveness of natural antioxidants in preventing lipid oxidation in food products. The study will focus on evaluating the antioxidant properties of selected natural compounds and their ability to inhibit lipid oxidation in model food systems. Chapter 1 provides an introduction to the research topic, including background information on lipid oxidation, the problem statement, objectives of the study, limitations, scope, significance, structure of the research, and definitions of key terms. Chapter 2 presents a comprehensive literature review covering ten key aspects related to natural antioxidants, lipid oxidation, food product stability, and relevant studies in the field. The literature review will provide a theoretical framework for the research and help identify gaps in existing knowledge. Chapter 3 outlines the research methodology, detailing the experimental design, sample preparation, antioxidant extraction and characterization methods, lipid oxidation assays, and data analysis techniques. The chapter also describes the selection criteria for natural antioxidants, food models used, and relevant parameters for evaluating antioxidant activity and lipid oxidation inhibition. In Chapter 4, the research findings are presented and discussed in detail. The effectiveness of natural antioxidants in preventing lipid oxidation in food products is evaluated based on the experimental results and statistical analysis. The chapter highlights the impact of different natural antioxidants on lipid oxidation kinetics, oxidative stability, and sensory attributes of the food products. The discussion also explores the mechanisms of antioxidant action and factors influencing their efficacy in inhibiting lipid oxidation. Chapter 5 concludes the research project by summarizing the key findings, implications for the food industry, and recommendations for future research. The conclusion emphasizes the importance of natural antioxidants as potential additives for enhancing the oxidative stability and shelf life of food products. Overall, this research contributes to the growing body of knowledge on natural antioxidants and their application in food preservation, addressing the need for safer and more sustainable alternatives to synthetic antioxidants.
