Abstract
The invention relates to a process for extracting nonpolar constituents from hops with simultaneous separation of residues of nonpolar plant protectives. In a first step the plant protective as well as other ingredients that are soluble under the chosen conditions are extracted with compressed gases, and in a subsequent stage the dissolved mixture is passed through an adsorbent and the plant protective is selectively removed from the mixture.
