Nutritional Enhancement of Plant-Based Fermented Foods: Microbial Innovations for a Sustainable Future

The rising demand for sustainable, nutritious, and functional food options has fueled growing interest in plant-based fermented foods. These products offer enhanced sensory, functional, and health-promoting properties, largely driven by microbial activity during fermentation. This review examines recent advances in microbial biotechnology—including the use of novel starter cultures, strain engineering, CRISPR-based genome editing, and precision fermentation that are reshaping the nutritional landscape of plant-based fermented foods. Key benefits such as improved protein digestibility, bioactive compound synthesis, antinutrient reduction, and micronutrient bioavailability are explored. Additionally, the review…
