The control samples, consisting of low-fat (1.5%, w/w fat) and full-fat (3.5%, w/w) yoghurts, were produced using the same process, but the milk was emulsified using a conventional valve homogenizer (20/5 MPa; GEA Niro-Soavi S.p.A., Italy). The yoghurt samples were stored at 5 C in a walk-in cold room for 2 weeks, during which instrumental and sensory analyses were performed.
