Thesis Abstract

Abstract
This thesis presents the research conducted on the development of an innovative food preservation technique utilizing natural ingredients. The project aimed to address the challenges of food preservation in a sustainable and eco-friendly manner by exploring the potential of natural compounds. The study involved the investigation of various natural ingredients known for their antimicrobial and antioxidant properties, with the objective of developing a novel food preservation method that could enhance shelf life while maintaining food quality and safety. The research began with a comprehensive review of existing literature on food preservation techniques, natural preservatives, and their mechanisms of action. The literature review highlighted the limitations of conventional chemical preservatives and emphasized the growing consumer demand for natural and clean-label food products. The review also identified gaps in current research, motivating the need for a new approach to food preservation using natural ingredients. In the research methodology, a series of experiments were conducted to evaluate the efficacy of different natural compounds, such as plant extracts, essential oils, and antimicrobial peptides, in inhibiting the growth of food spoilage microorganisms. Various parameters, including concentration, pH, temperature, and storage conditions, were optimized to determine the most effective combinations for food preservation. Microbiological analysis and sensory evaluations were carried out to assess the microbial stability and organoleptic properties of the preserved food samples. The findings from the study demonstrated the potential of natural ingredients as effective alternatives to synthetic preservatives in extending the shelf life of perishable foods. The results revealed that certain natural compounds exhibited strong antimicrobial activity against a wide range of foodborne pathogens and spoilage microorganisms. Moreover, the sensory evaluations indicated that the use of natural preservatives did not compromise the taste, texture, or overall quality of the preserved foods. The discussion of the findings delved into the implications of the research outcomes for the food industry, highlighting the benefits of adopting natural preservation techniques in terms of consumer acceptance, regulatory compliance, and environmental sustainability. The challenges and limitations encountered during the study, such as stability issues, formulation complexity, and cost considerations, were also addressed, suggesting areas for future research and development. In conclusion, the development of an innovative food preservation technique using natural ingredients represents a promising approach to meet the increasing demand for safe, healthy, and sustainable food products. This thesis contributes to the field of food technology by offering a novel solution to the challenges of food preservation while promoting the use of natural and bio-based ingredients. The research outcomes have practical implications for food manufacturers, policymakers, and consumers seeking natural alternatives to conventional preservatives, paving the way for a more environmentally friendly and health-conscious food industry.
