Abstract: With the increasing demand for health among modern individuals, the development of functional foods has become a significant research direction in food science and biotechnology. This study focuses on food biotechnology to explore its potential applications and practical effects in the development of functional foods, aiming to enhance their functional value through advanced biotechnological approaches to meet consumers' dual needs for nutrition and health. Multiple biotechnological methods, including genetic engineering, enzyme engineering technology, and microbial fermentation technology, were employed to systematically analyze the extraction, transformation, and optimization of specific functional components. By processing and treating various raw materials, functional foods rich in polyphenols, probiotics, and functional peptides were successfully prepared, and their bioactivities were comprehensively evaluated. The results demonstrated that the application of food biotechnology could significantly improve the extraction efficiency and purity of functional components while enhancing product stability and bioavailability. Furthermore, this study innovatively proposed a directed modification strategy based on synthetic biology to optimize microbial me tabolic pathways for the efficient production of target functional components. This strategy not only substantially reduced production costs but also provided theoretical support and technical assurance for the large-scale industrial production of functional foods. In summary, this study not only validated the feasibility and superiority of food biotechnology in the development of functional foods but also laid a solid foundation for future in-depth research in related fields, possessing important academic and practical significance.
