A well-known problem in yogurts and other dairy products is syneresis. This chemical or physical effect occurs during the storage of two-phase systems and can lead to compromised quality: the unsightly release of water caused by phase separation. In yogurt, it’s the whey separating from the yogurt curds. By lowering the interfacial tension and, at the same time, binding and thus immobilizing the water, gelatine emulsifies and stabilizes the compounds, prevents syneresis and ensures an appealing end product during the entire storage period.
