In this study, general composition, some quality parameters and sensory characteristics of butter samples produced by using yogurt and kefir were analyzed comparatively on the 1st, 30th and 60th days of storage. In butter samples significant difference was observed in titratable acidity values depending on the use of different starter cultures. Acid degree and peroxide values representing lipolytic and oxidative stability in the samples were determined as 0.89-1.11 mg KOH/g fat and 0.19-0.40 mek O2/kg fat, respectively. These characteristics were found lower than the limits given in regulations at which some flavor defects occur. A distinct color difference, represented by ΔE, was observed in butter produced by kefir on the 30th day. Although there was no distinct difference in appearance and texture of the butter samples, taste, flavor and general acceptability characteristics were found different and butter produced by using kefir was liked more than the other sample.
