【 摘 要 】

Supercritical fluid extraction (SFE) of liquid samples can, despite certain problems, be considered a new prospective method, which, after further perfecting it, could establish itself in the field of analysis of trace amounts of sensory active substances in beer. In the article, the first results of extracting sensory substances from beer (alcohols, fatty acids and their esters) are presented. The method is gentle and environmentally friendly, it does not affect the analyzed material and uses a limited amount of organic solvents. Therefore, it corresponds with the modern trends in analytic chemistry and meets the demands of protecting the environment.
