摘要

In the globalized world, the interaction between ethnic foods and biotechnology has profoundly transformed fermentation, creating avenues for innovation while respecting traditional methods. Globalization fosters cultural exchange, making ethnic fermented foods more accessible and popular. From Asia’s kimchi and Europe’s sourdough to Africa’s injera, South America’s chicha, North America’s curtido, and the Middle East’s kishk, these foods are celebrated for their unique flavors, health benefits, and cultural significance, reflecting the heritage and social values of various communities. Integrating biotechnology into fermentation enhances these processes, meeting consumer interest in nutrient-dense, probiotic-rich products that align with current dietary trends without compromising the cultural essence of ethnic foods. A key contribution of biotechnology lies in optimizing microbial strains through selection or genetic modification, promoting beneficial traits like faster fermentation and improved flavor. Additionally, biotechnology supports precise control over fermentation conditions—such as temperature, pH, and oxygen—ensuring consistent quality.
