Determination of certain quality characteristics, thermal and sensory properties of ice creams produced with dried Besni grape (Vitis vinifera L.)

Abstract

In this study, the effect of adding dried Besni grape (BG) at different concentrations on the physico-chemical characteristics, colour values, total phenolic and flavonoid contents, glass transition (T-g'), melting (T-m'), freezing (T-f) and melting (T-m) point temperatures, and sensory properties of ice creams was investigated. Generally, the addition of BG caused a statistically significant (P < 0.01) increase in total solids, ash, fat, viscosity, first dripping times, complete melting times and a* colour values, while it decreased protein, pH, overrun, L*, b*, T-g', T-m', T-f and Tm values. The colour scores of ice cream samples showed a statistically significant increase (P < 0.05) with the increment of BG concentration, while the effects of BG addition on texture, resistance to melting, flavour, gumming structure and overall acceptability scores were not statistically significant.
