Thesis Overview

The project titled "Development of novel food preservation techniques using natural ingredients in Food Science and Technology" aims to address the growing demand for sustainable and natural food preservation methods in the food industry. With increasing consumer awareness and preference for clean-label products, there is a need to explore innovative ways to extend the shelf life of food products without compromising on quality and safety. This research project focuses on leveraging natural ingredients as effective alternatives to synthetic preservatives, which are often associated with health concerns. The research will begin with a comprehensive review of existing literature to gain insights into the current trends, challenges, and opportunities in the field of food preservation. This will include an analysis of various natural ingredients with antimicrobial properties and their potential applications in food preservation. By synthesizing information from previous studies, the project aims to identify gaps in knowledge and potential areas for further exploration. Following the literature review, the research methodology will be designed to experimentally investigate the efficacy of selected natural ingredients in preserving different types of food products. This will involve conducting laboratory experiments to assess the antimicrobial activity, shelf life extension, and sensory properties of food samples treated with natural preservatives. The methodology will also include analytical techniques to analyze the chemical composition and safety of the preserved products. The findings from the experimental studies will be presented and discussed in detail in the results and discussion chapter. This section will highlight the effectiveness of natural preservatives in inhibiting microbial growth and maintaining the quality of food products over time. The research will also explore the potential mechanisms of action of these natural ingredients in preserving food, providing valuable insights into their mode of action. In the conclusion and summary chapter, the key findings of the research will be summarized, and the implications of the results will be discussed in the context of the food industry. The project will conclude with recommendations for future research directions and practical applications of novel food preservation techniques using natural ingredients. Overall, this research project aims to contribute to the development of sustainable and eco-friendly food preservation methods that align with consumer preferences for natural and clean-label products. By exploring the potential of natural ingredients as effective preservatives, this study seeks to offer valuable insights and practical solutions to the food industry in enhancing food safety and quality while meeting the demands of modern consumers.
