Abstract: Metabolomics is a important branch of system biology and has been widely used in the study of food science pharmacology because of its high efficiency and high throughput.This paper outlined the separation and detection techniques of metabolomics,described the application examples of metabolomics in the identification of lactic acid bacteria,fermentation regulation,intestinal probiotics,etc.,and discussed the potential problems and future development trends of metabolomic research in lactic acid bacteria,which could provide the information of the metabolomics application in food industry.

Key words: lactic acid bacteria, metabolomics, study, application
