Results demonstrated that PFPP reduced significantly the maximum acidification rate in both skim and whole milk and reduced the fermentation time in all skim yoghurts, except the one fermented with B. lactis Bl04. Total titratable acidity was higher in skim yoghurts, especially in those with PFPP, indicating a lower buffering capacity of the skim milk regarding the whole one. In general, skim yoghurts presented higher counts of probiotic bacteria than the whole ones. The yoghurts with passion fruit peel powder had variable counts of probiotics but similar to those of control yoghurts in most of the cases. Passion fruit peel powder increased cohesiveness of all probiotic skim yoghurts. However, in the case of some whole yoghurts, the PFPP decreased firmness and consistency regarding the respective controls without the powder. The data show that the addition of PFPP into the yoghurt effects differently the parameters studied depending on the combination of bacteria and mainly on the milk type, being in general more favorable in the case of skim yoghurts.
