Abstract

This study investigated the effects of adding grape, mulberry and carob molasses (Pekmez) at 6%, 10% or 14% on titratable acidity, pH, viscosity, whey separation, water holding capacity (WHC), gel firmness, acetaldehyde, volatile fatty acids, colour values, mineral profile and sensory properties of set-type yoghurts. Increasing concentration of the molasses decreased whiteness value, viscosity and WHC, but increased redness/greenness and yellowness/blueness values, whey separation and mineral contents of the samples significantly (P < 0.05). Nevertheless, the yoghurts produced by adding grape molasses had the highest points in the sensory evaluation, followed by mulberry and carob molasses.
