Abstract
Abstract A preliminary study was undertaken to establish the potential of supercritical fluid chromatography (SFC) for the rapid analysis of hops. Seven varieties of pelleted hops were extracted in ethanol with ultrasound and separated with SFC using carbon dioxide modified with ethanol as the mobile phase. The major terpenes and terpenoids, as well as the alpha and beta hop acids, were separated in a single run. The injection-to-injection run time was 13 min. At the current state of development, this method provides a rapid fingerprint of an extracted hop sample. Refinement of the extraction procedures and of the chromatographic parameters can be expected to yield more detailed analytical information on both the hop acids and the hop oils.
