Abstract
We have developed clean withont and rapid analytical methods for aflatoxins, ochratox-in A, fumonisins and patulin wlthout using chloroform and an immunoaffinity column. With regard to the fumonisin analysis, we developed a postcolumn derivatization HPLC method. Since the mobile phase does not contain a non-volatile buffer, we can utilize it for LC/MS analysis to confirm the fumonisins.
