英文摘要:

      The exopolysaccharides (EPSs) produced by lactic acid bacteria were natural biological polymers with many special functions such as improvement of textural characteristics of fermented dairy products and beneficial health effects for human beings. EPSs of lactic bacteria had been extensively and thoroughly studied with respects to the structure and function, as well as their relations. This paper reviewed the research advances on the EPS types, chemical composition, structure and function, in order to provide references for further research and development of functional foods related to the EPSs of lactic acid bacteria.
