Özet

The objectives of this study were to manufacture lyophilised purslane-fortified yoghurts in order toimprove the functional properties of yoghurt and to optimise processing and storage conditions offortified yoghurts. A central composite design was created by considering the storage time (5–12 days), lyophilised purslane concentration (0.25–0.5%) and starter culture ratio (1–3%) as fac-tors. The fortified yoghurts were supplemented by phenolics (up to 36.94 mg gallic acid equivalentper kg) and linoleic acid (3.15–11.31%). The optimal fortified yoghurt processing and storageparameters were determined to be 0.55% lyophilised purslane, 3.41% starter culture ratios and5 days of storage at 4°C.
