Thesis Abstract

Abstract
Food preservation is a critical aspect of the food industry to ensure food safety and quality. The use of natural antimicrobial compounds has gained increasing attention as an alternative to synthetic preservatives due to consumer demand for clean label products. This thesis investigates the effectiveness of natural antimicrobial compounds in food preservation, focusing on their antimicrobial properties and potential applications in extending the shelf life of various food products. The research begins with a comprehensive literature review to explore the existing knowledge and research gaps in the field of natural antimicrobial compounds. Various natural sources of antimicrobial compounds, such as plant extracts, essential oils, and antimicrobial peptides, are examined to understand their mechanisms of action and potential benefits in food preservation. A detailed methodology is developed to investigate the antimicrobial effectiveness of selected natural compounds against common foodborne pathogens. The study includes in vitro experiments to assess the antimicrobial activity, minimum inhibitory concentration, and synergistic effects of natural compounds when combined with traditional preservatives. Furthermore, the stability and sensory impact of natural antimicrobial compounds in food matrices are evaluated to determine their feasibility for practical applications. The findings of the research reveal the significant antimicrobial activity of certain natural compounds, highlighting their potential as effective preservatives in food products. The results also demonstrate the importance of synergistic interactions between natural and traditional preservatives in enhancing antimicrobial efficacy and minimizing microbial resistance. The discussion section critically analyzes the implications of the research findings in the context of food preservation strategies and regulatory considerations. The challenges and limitations of using natural antimicrobial compounds in food products are addressed, along with potential solutions to overcome these barriers. In conclusion, this thesis provides valuable insights into the effectiveness of natural antimicrobial compounds in food preservation and their potential as sustainable alternatives to synthetic preservatives. The significance of this research lies in its contribution to the development of safer and healthier food products that meet consumer preferences for natural and clean label ingredients.
