Abstract
Food biotechnology, as a crucial branch of modern food science, demonstrates significant potential in the nutritional improvement of food. This study aims to enhance the nutritional value of food by integrating gene engineering, enzyme technology, and fermentation processes to optimize the nutritional composition and functional properties of specific food materials. Through the construction of high-efficiency ex pression systems and the screening of high-yield strains, the content of key nutrients in target foods was successfully increased, along with a marked improvement in their bioavailability. Innovatively, this research proposes a precision nutrition improvement strategy based on synthetic biology, enabling controllable regulation of trace nutrients in food. Experimental results indicate that this technology effectively elevates the levels of active components such as vitamins, minerals, and functional peptides in food while preserving its original sensory quality. This study not only provides new insights into food nutritional improvement but also lays a theoretical and technical foundation for the development of personalized nutritional foods, demonstrating important academic significance and application prospects.
