Food fermentation is an ancient bioprocess characterized by complex biochemical transformations driven primarily by microbial communities. Across the diverse regions of China, various ethnic groups have developed a rich array of traditional fermented foods through long-term practical experience. These foods are integral to local culinary heritage and provide valuable systems for studying microbial ecology and function. From the perspective of microbial interactions, this review summarizes key concepts and major interaction types-including mutualism, commensalism, and competition-and describes how bacteria, yeasts, and molds interact via metabolic division of labor to drive substrate conversion, flavor formation, preservation, and biosynthesis of functional compounds. Focusing on four representative ethnic fermented foods-Dong fermented fish, Mongoslian milk curd, Miao sour soup, and Manchurian kombucha-we analyze how microbial interactions contribute to product quality, safety, and sensory attributes. Given current challenges in industrializing traditional fermented foods, such as poor standardization and variable quality, we propose future research directions centered on modern microbiome tools, designed microbial consortia, and process optimization. This work aims to provide a scientific foundation and practical strategies for modernization and quality improvement of traditional fermented foods.
