Abstract
This study was conducted to evaluate the chemical and organoleptic properties of some dairy products supplemented with different concentrations of propolis (0%, 0.5%, 1.0%, 1.5%, and 2.0%). There was no significant difference between pH values of the treated and control groups. All samples were tested using 20 evaluators divided in five categories. Compared to the control, the best organoleptic test results were obtained for market milk, yoghurt, and Kefir supplemented with 0.5% propolis. Statistical difference was observed in the taste, flavor, color, texture, and overall acceptability of market milk, yoghurt, and Kefir between the treated and control groups (p<0.05). However, as propolis has a strong aromatic flavor, it should be supplemented in small amounts, so as not to affect the organoleptic properties of the product. In conclusion, this study provides useful information for the development of functional dairy products using propolis.
