The diverse community of bacteria that are present in food products naturally is referred to as the food microbiota. These microbes are crucial in determining the sensory qualities, safety, and shelf life of different foods. Food microbiota has an impact on the flavor, texture, and general quality of a wide variety of culinary creations, from the tart fermentation of yogurt to the intricate flavor profiles of aged cheeses. These bacteria play an important role in the growth and preservation of food, but they can also have significant effects on human health. Food scientists and consumers must both understand the complex relationships found in the food microbiota because doing so can improve food safety, advance product development, and give us a better understanding of the complex world of microbes that live inside our daily meals [1].

The goal of food preservation is to maintain the safety and quality of food products over extended periods of time. The preservation process uses a number of methods, including cooling, canning, and drying, which are intended to prevent microbial development and spoilage. The relationship between food preservation factors and the local microbiota, particularly their impact on the formation of acylated homoserine lactones (AHLs) by Enterobacteriaceae, has recently begun to come to light as an intriguing component of food preservation, though [2].

AHLs are signaling molecules that are principally linked to quorum sensing, a method used by bacteria to control gene expression in response to cell density. Although this communication mechanism has been extensively researched in the context of pathogenic bacteria, it is now becoming more widely known in non-pathogenic, food-derived microbes, notably those belonging to the family Enterobacteriaceae. These microbes' production of AHLs has consequences for human health as well as sensory qualities and food preservation in addition to food [3].

Temperature, pH, and the presence of rival microbes all seem to have an impact on the pace at which Enterobacteriaceae produce AHLs in food products. Researchers have shown that the synthesis of AHL tends to rise in environments that are favorable for bacterial development, such as when food is kept at temperatures that encourage the growth of Enterobacteriaceae. Gaining knowledge of how these preservation factors impact AHL production can be extremely beneficial for understanding the dynamics of microbial communities in preserved foods [4].

Another fascinating element of this research is how well AHLs maintain their stability in preserved food products. AHLs produced by Enterobacteriaceae may be stable under some circumstances, but the degree of this stability is still unknown given the lengthy shelf life of many preserved foods. The permanence of AHLs in preserved foods may be influenced by elements like the type of packaging used, the amount of oxygen present, and the presence of antimicrobial substances [5].


As our understanding of food microbiology continues to evolve, it is becoming increasingly clear that the local microbiota and food preservation parameters are integral components of the complex microbial ecosystems present in our food products. The production rate, profile, and stability of AHLs by food-derived Enterobacteriaceae represent a fascinating intersection of food science, microbiology, and sensory analysis. Exploring these dynamics can lead to improved food preservation methods, enhance the development of unique flavor profiles in fermented foods, and provide valuable insights into the potential impacts of AHLs on human health. In an era of increasing interest in the human gut microbiome and its influence on health, understanding the role of AHLs in food-derived Enterobacteriaceae adds a new layer of complexity to our appreciation of the microbial world within our meals.
