This study aimed to evaluate the quality parameters in probiotic yogurt produced with Brazilian red propolis
to replace potassium sorbate used in conventional yogurt (CY). Microbiological stability and shelf life, physicochemical
properties (pH, acidity, chemical composition, and fatty acids), and bioactive properties (phenolic compounds and
antioxidant activity) were evaluated. The addition of red propolis (0.05%) to replace the potassium sorbate did not change
the pH, acidity, fatty acid profile, chemical composition, or shelf life. Microbiological stability of at least 28 days was
achieved, while a drastic reduction in the lactic acid bacteria content was observed in the CY during refrigeration storage.
Phenolic total contents were higher than those of the control, and consequently, yogurt with red propolis showed higher
antioxidant activity.
