The effects of the technological processes (soaking in water or alkaline solutions, drying, puree preparation) and the supplementation with maize flour on the nutritional value and on the organoleptic characteristics of broad bean (Vicia faba, L. major) flakes have been studied. Protein content was not affected by technological process. The addition of maize flour decreased the protein content of the final product depending on the amount of the maize flour added. Amino acid composition showed a decrease of tryptophan due to technological processing. Supplementation with maize flour improved the amino acid pattern and, except for tryptophan, the amount of essential amino acids in the flakes supplemented with 25% or more maize flour well compared with the provisional pattern by F.A.O. In vitro digestibility trials did not evidence significant changes due to technological processes or to integration of broad beans with maize flour. Broad bean toxic factors (vicine and convicine glycosides) were only slightly affected by the alkaline treatment of the flakes. Glycosides content decreased with the increasing supplementation with maize flour but the relationship was not linear. The organoleptic tests were positive for texture and taste, whereas the appearance of the products should be improved.
