Abstract
A method is described for ochratoxin B analysis, which is adapted to the earlier described method of ochratoxin A analysis, using carboxypeptidase A (K. Hult and S. Gatenbeck, J. Assoc. Off. Anal. Chem. 59:128-129, 1976). The fluorescence spectra of ochratoxins A and B coincide too much to allow direct discrimination of the two compounds. A method using the differences in kinetic parameters of the enzymatic hydrolysis of the two compounds is suggested for the analysis of mixtures of the ochratoxins.
