Abstract

Abstract:

Lactic acid bacteria, as beneficial microorganisms, are of great significance in ensuring food safety, improving quality, and promoting health in the food industry. To clarify the mechanism of action of lactic acid bacteria in ensuring food safety and explore effective ways to enhance their application efficiency, this study summarizes current research on lactic acid bacteria in alleviating microbial contamination and degrading toxic and harmful substances, and discusses the feasibility of improving the growth efficiency of lactic acid bacteria and the quality of fermentation products by optimizing medium components (including the selection and combination of carbon sources, nitrogen sources, minerals, and growth factors). Meanwhile, it analyzes the current challenges in balancing production costs with meeting consumers' demands for food safety, nutrition, and flavor. Future research will focus on developing economical and efficient composite medium systems to strengthen their role in enhancing the food safety functions of lactic acid bacteria. This study aims to provide a theoretical reference for the selection and research of raw materials for food-applied lactic acid bacteria culture media.

Key words: lactic acid bacteria, medium optimization, food applications, food safety, food-grade ingredients
