The aim of the study was to investigate the changes in the essential oil constituents of coriander and caraway when treated with UHP and/or elevated temperatures in a helium atmosphere. The UHP and/or heat treatment was conducted for 30 mins at 800 MPa, the temperature range was 60-121°C. The changes in the volatile oil content did not exceed 5% in all the treatment conditions. The pressure and temperature...
Próbki czarnego pieprzu (Piper nigrum L.) zamknięte w atmosferze argonu poddawano dekontaminacji mikrobiologicznej w czasie 30 min w podwyższonej temperaturze (60, 80 i 100°C) oraz pod wysokim ciśnieniem (UHP) 1000 MPa w temperaturze 60, 80, 100 i 140°C. Oznaczano zmiany zawartości olejku lotnego i piperyny oraz składu substancji lotnych metodą GC i GC-MS. Zawartość olejku lotnego uległa istotnemu...
