Food Chemistry v. 114, no. 1, p. 93-99Summary: The present paper aimed to study the development of the Maillardreaction during the drying?toasting step of different flours usually employed for the formulation of cereal-based products. The results state the idea that a great part of hydroxymethylfurfural (HMF) and furfural found in cereal-based products are supplied by the rest of the ingredients composing these foods and not from the toasting of the floursemployed. Moreover, a high furfural generation was associated to the fibre-enrichment of whole wheat flour. Glucosylisomaltol (GIM) measurement could be established as a useful indicator for controlling the manufacture conditions of cereal-based products, if significant amounts of maltose are present. Furosine determination is suitable for flours with either low or high reactivity due to its inherent sensibility to thermal treatment but, in extremely reactive flours like soybean, HMF shows better application. Finally, the ÄE parameter resulted in a reliable measurement of the visible colour production for the toasting step of the flours studied.
