Abstract

The tannin content in 15 cultivars of faba beans was determined with four different colorimetric methods, viz. the Folin-Denis method, the Prussian blue procedure, the ‘ISO method’ and the vanillin assay. With the Prussian blue procedure unsatisfactory results were obtained in that the reproducibility was poor.

The data obtained with the vanillin assay are highly correlated with those obtained with the Folin-Denis method or the ISO method. This is surprising because the nature of the chemical reaction of vanillin with tannins is quite different from the type of reaction that takes place in the Folin-Denis and in the ISO method.

The tannin content in the faba beans was also established with a protein precipitation procedure. No correlation was found between the results of this precipitation procedure and the colorimetric methods mentioned.
