The content of essential oil in hop cones and possibilities if its usage

Popis výsledku v původním jazyce

The aim of this work was to determine the essential oil content in hop cones of the Saaz variety, harvest years 2010 and 2011. The essential oil content was determined by the means of steam distillation. Analysis of individual components was performed via gas chromatography / flame ionisation detection (GC/FID). Gas chromatograph HP-4890D with FID was used for the identification and ratio determination of the analytes of interest. The differences in the essential oil content were found in both evaluated years. The essential oil content found in the samples from 2011 was much higher compared to the year 2010. The amount of selected components - myrcene, caryophyllene, farnesene and humulene - was determined in the essential oil. The highest content of myrcene was found in samples from 2011 from hop-growing region Trsice (56.9 %). The highest content of caryophyllene was found in samples from 2011 from hop-growing region Saaz (18.3 %). The content of farnesene wasn't statistically significantly different in both evaluated years in hop-growing regions Trsice and Ustek. The content of farnesene in these samples varied in the range of 12.0 - 12.5 %. Humulene was the second highest contained component in the essential oils. The results indicate that the content and composition of the essential oil depends on the growing region and on the weather course during the harvest year. Hop essential oils have, among others, antibacterial effects and could be used also for the stabilisation of non-beer beverages from the view-point of microbial purity.
