All beverages presented minimal counts of
8 log cfu/mL of Lb. acidophilus, and pH ranged from
4.09 to 4.14. Increasing the whey content increased
the fragility of the gel structure, probably because
of the replacement of casein by whey proteins, once

acceptance of the probiotic dairy beverages; beverages
with whey contents greater than 65% resulted in lower
acceptance by consumers.
