Abstract

Studies of the chemical composition of essential oil of Hope more than 200 constituents in hops (Humulus lupulus) have been characterized and quantitified by means of distillation- extraction, capillary gas chromatography and chromatography-mass spectrometry.
Various cultivars of hop, are used in brewing process to impart a bitter taste and hop flavor,as well as a characteristic aroma to beer.
In addition, the mist important volatile components identified were :α-Bisabolene(20.55%),
Caryophyllena(17.88%), Carvone oxide(6.18%), and α-Humulene (1.80%) are known as constituents in beer.
