Abstract :Ice cream is classified as a dairy product or frozen dessert. Various fruits have been incorporated into ice cream formulations to enhance their quality and nutritional properties. In this study, ice creams were prepared with barberry at four different concentrations (0%, 5%, 10% and 15%). The physicochemical, rheological characteristics, antioxidant activity, mineral content and sensory properties of the samples were examined. With the addition of barberry, the dry matter (DM), acidity and overrun values increased, while pH and fat content decreased. The viscosity and consistency coefficients were highest in the samples containing 10% and 15% barberry. All samples exhibited pseudoplastic flow behavior. The colorimetric parameters showed significant differences among the samples, except for the C* value. The sample with 5% barberry had higher levels of Ca, Na, Mg, S, Fe and Zn compared to the other barberry-added samples. The sample containing 15% barberry demonstrated the highest DPPH scavenging activity (22.15 μg/mL) and total phenolic content (TPC) (1474.04 mg GAE/g), while the sample without barberry had the lowest values (143.19 μg/mL and 149.48 mg GAE/g, respectively). Additionally, the control sample received the lowest scores for gumming structure, texture, melting in the mouth, resistance to melting and overall acceptability. These findings suggest that incorporating 10% barberry could enhance the quality and nutritional value of ice creams.
