摘要:

乳酸菌作为有益微生物,在食品工业中对保障安全、提升品质和促进健康意义重大。为了阐明乳酸菌在保障食品安全中的作用机制并探索提升其应用效能的有效途径,本研究系统归纳了乳酸菌缓解微生物污染、降解有毒有害物质的研究现状,深入探讨了通过优化培养基成分(包括碳源、氮源、矿物质和生长因子的选择与组合)来提高其生长效率与发酵产物质量的可行性。同时分析了当前平衡生产成本与满足消费者对食品安全、营养及风味需求所面临的挑战。未来研究将聚焦于开发经济高效的复合培养基体系,强化其在增强乳酸菌食品安全功能方面的作用。本研究可为食品应用型乳酸菌培养基原料的选用和研究提供理论参考。

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.
