摘要： The present invention relates to a process for the crystallization of a solid phase from a liquid, characterized in that the liquid during crystallization is subjected to ultrasound in the absence of transient cavitation. In particular the liquid is sonicated under such conditions of time and frequency that nucleation of stable crystals in the liquid is induced without exceeding the cavitation threshold and the occurrence of transient cavitation and the accompanying flavor deterioration is avoided. The liquid preferably is a triglyceride oil such as a vegetable oil or animal fat, e.g. liquefied milk fat.
