The paper presents research results concerning the influence of ultrasound pre-treatment on the process of distillation of essence from caraway seeds. Tests were carried out in two variants. In the first one, whole seeds were subjected to distillation process, and in the second one ground seeds. An ultrasound processor (Sonic VC 750) with a head of 19 mm diameter operating with frequency 20 kHz was used for generating ultrasounds. The following parameters of initial sonification of seeds were applied: treatment time from 20 to 60 minutes, intensity of ultrasounds: 28 and 42 W•cm-2. It was found out that the initial ultrasound treatment of caraway considerably speeds up the rate of obtaining essence and increases the final efficiency of the process. Depending on the time and intensity of ultrasounds the increase of efficiency from 9 to 40% was reported. Moreover, a significant impact of seeds fragmentation on the kinetics of the distillation process was reported.
