lentil flour also resulted in faster acidification but this only became significant after 2.5 h of incubation. Milk has greater buffering capacity in comparison with lentil flour (Table 1). Therefore, the greater acidification rates in products supplemented with lentil flour could have been simply due to their lower buffering capacity when compared to corresponding skim-milk-supplemented yogurts. This is not the case however, when the data with lentil flour are compared to the control. The latter suggests that growth of the yogurt strains could have been stimulated by lentil flour, and viable counts were carried out on the products.
