  9. Bio-enrichment of vitamin B12 in plant-based food via fermentation

    Gao, LuChristian-Albrechts-Universität zu Kiel

    Vitamin B12 deficiency is common among individuals following strictly plant-based diets. This issue is amplified by the growing preference for organic products, which are often not vitamin-fortified. As vitamin B12 is naturally produced by bacteria, fermentation offers a sustainable strategy to …
