QUALITY OF HOPS AT DIFFERENT DRYING TEMPERATURES IN CHAMBER DRYER
Original language description
The drying temperature during the measurement reached 60 degrees Celsius (conventional method) and 40 degrees Celsius (low temperature method). During this measurement, we monitored the output qualitative parameters of the Saaz hop variety in the form of essential oils. During the measurement, an analytical method to determine humulinones, which are one of the components of essential oils in hops and hop products, was newly developed. The measurement confirmed that when drying hops in chamber dryer at a temperature of the drying medium being 40 degrees Celsius, the drying period is extended by approx. 46%. The graphs clearly show the difference in the amount of essential oils contained in the hops dried at 60 degrees Celsius and 40 degrees Celsius. Based on the analytical results it can be concluded that by drying a large majority of the essential oil components is reduced to the approximately same extent, therefore the relative representation in the mixture does not change significantly.
