“…In addition, the proteins which would have helped to stabilize the emulsions had been denatured by heat processing. The oil absorption capacities of the composite flours tended to increase with increase in protein content (Table 1) since the protein in foods influences fat absorption (Richest et al, 1974). The composite flours contained denatured proteins with high affinity for water (Padmashree, 1978) and no significant differthat cocoyam starch is not susceptible to retrogradation thus rendering it suitable for complementary food manufacture.…”

“…The general increase in both water and oil absorption capacities of maize flour with an increase in the steaming duration may be attributed to the seeming severe disruption in the structural make-up of the starch in the flour occasioned by the steaming operation. It had earlier been observed that the increase in the water absorption capacity of pregelatinized flour might be due to such factors as higher degree of damaged starch in the flour (Chilton and Collison 1974;Kurimoto and Shelton 1988;Adeyemi et al 1989) while the increase in oil absorption capacity was attributed to degree of denatured protein constituent in the flour, temperature of treatment and particle size of the flour (Richest et al 1974). The damaged starch content in maize flour obtained from steamed maize grits is also presented in Table 1.…”

“…En ce qui concerne les propriétés fonctionnelles, un traitement thermique de 60°C, 30 min à pH 7, améliore les proprié-tés moussantes des concentrés obtenus par filtration sur gel (Richert et al, 1974) ainsi que le volume spécifique et la stabilité de la mousse (Hansen & Black, 1972).…”

“…Un traitement de chaleur à 55-65°C appliqué aux CPL améliore la solubilité (Nakai & Li-Chan, 1985) et facilite l'orientation des protéines du lactosérum à l'interface air-eau (Richert et al, 1974). Entre 40 et 65°C, à pH neutre ou légèrement alcalin, le traitement de chaleur a un effet positif sur le pouvoir moussant des protéines du lactosérum (Richert et al, 1974;Paquet et al, 1978;De Wit & Klarenbeek, 1984).…”
