Abstract: A pilot study for determination of vanillin in fermentation broth with the TLC method and TBA spectrophotometeryand HPLC method has been carried out. It was found that TLC method could be used to quantitative analysis. The experimentalso showed that TBA spectrophotometery, HPLC method have a good relationship, and could be reproducible. Besides theHPLC method, the TBA spectrophotometery was simple and practical for determining vanillin in the fermentation broth.

Key words: vanillin, TLC, TBA spectrophotometery, HPLC
