Abstract：The optimum strains were selected from bean sprouts using rapid separation high performance liquid chromatography（RP-HPLC）to determine organic acids contents of different bean sprouts．The composition and content of different organic acids were determined by this method．By combining sense test with physical and chemical properties tests，the types and contents of organic acids from different fermentation strain samples were tested．The results showed that optimum fermentation strains were AN1∶AE composite bacteria．The total content of organic acids was the highest in the fermentation product．It can reach 35.97 mg?g-1．
