The water in the saliva was found to have had a significant dilution effect (Fig. 5B), as expected, causing all the systems to present lower K and higher ท values (Table 1). The flow curve behavior pattern was the same as when no saliva was added, but the values were lower for the whole set of samples. The fact that the K, ๆ50 and Oo values after in vitro oral digestion were higher in the samples containing starch than in the corresponding yogurts without starch indicated that the starch granules were not broken down by the a-amylase in the saliva
