Water intended for use as an ingredient in the production of beer (brewing liquor) or other foods
Oils and fats dispersed in water are precipitated using aluminum sulfate. After dissolving the precipitate with hydrochloric acid in organic solvents, they can be separated from the mineral salts.
This method describes the determination of four hop aroma compounds found in hops and hop products using gas chromatography.
Hops and hop products intended for use in beer brewing or elsewhere in the food industry
The hop oil obtained through steam distillation (refer to links) is dissolved in an organic solvent, separated into its components by means of gas chromatography and determined with a flame ionization detector. The contents are expressed as a percentage of the area of each component compared to the overall area of the peak.
