The aim of this study was to produce chocolate goat dairy beverages with the probiotic Bifidobacterium
lactis and to evaluate the effects of goat cheese whey and prebiotics (inulin and oligofructose) on the
physicochemical parameters and sensory features of the beverages. All of the formulations (n ¼ 7)
exhibited decreased pH values and a concomitant increase in acidity during refrigerated storage. Beverages
made with the lowest amounts of whey (F1 and F3) exhibited a greater decrease in pH after 14
days of storage. The apparent viscosity increased for up to 21 days for all formulations and up to 28 days
for F4 (6 g 100 mL1 prebiotics and 45 mL 100 mL1 whey). B. lactis exhibited counts between 6 and 8 log
CFU mL1. F4 presented the highest median sensory attributes for flavor and aroma, which may be
related to the larger amounts of prebiotics and whey in this formulation. Thus, F4 is considered to be the
formulation that best represents the desirability profile chosen for the probiotic chocolate goat dairy
beverage as defined as probiotic viability above 7 log CFU mL1 and improved viscosity and sensory
features.
