Abstract
In this paper, the complexity and diversity of microbial community structure in traditional fermented foods and the multiple functional properties of these microorganisms during food fermentation were studied in depth. By analyzing major fermented food types such as dairy products, legumes, cereals and vegetables, we reveal the microbial populations that are unique to different types of food and the strong links between them and food quality. This paper not only introduces the limitations of traditional culture isolation methods in modern microbiology, but also discusses the latest progress and application of modern molecular biology techniques, biomarker methods and community level physiological fingerprinting (CLPP) in the analysis of microbial community structure. In terms of the functional characteristics of microorganisms, this paper systematically discussed how microorganisms improve the flavor and texture of fermented food through me tabolic activities, and how to increase the nutritional value of food, such as increasing vitamin content and promoting mineral absorption, etc., and in-depth analyzed the role of microorganisms in giving food health benefits, such as antioxidant, antibacterial and regulating the balance of intestinal microorganisms. In addition, we also discuss the important role of microorganisms in extending the shelf life of food, including inhibiting the growth of harmful microorganisms and improving the storage resistance of food. With the development of science and technology, modern fermentation technology has been widely used in traditional fermented food production. This paper discusses the feasibility of improving the quality and production efficiency of fermented food by means of screening and optimization of microbial strains, precise control of fermentation conditions, application of automatic and intelligent fermentation equipment and development of new fermentation technology. In particular, in terms of strain screening and optimization, we emphasize the importance of screening microbial strains with excellent characteristics according to the needs of specific fermented foods, and optimizing their performance through genetic engineering, me tabolic engineering and other means.
