Sazetak: The effects of Lactobacillus casei BGP93 used as adjunct culture on the physicochemical, textural and sensory characteristics of a dairy beverage processed with goat Coalho cheese whey powder and Streptococcus thermophilus TA-40 as starter (ST-LC beverage) were investigated in comparison to a control product (ST beverage) without L. casei. No significant differences were observed between the ST and ST-LC trials concerning the acidification pattern throughout the fermentation process (P>0.05). Post-acidification was also not observed for both trials since their pH values were maintained stable, without significant differences during 21 days at 4 ± 1 °C. This pH stability reinforced the maintenance of firmness, consistency, cohesiveness and viscosity index without significant differences between the sampling periods throughout the whole storage in both trials, and also that no significant difference was verified between the ST and ST-LC beverages in the sensory evaluation (P>0.05).
