Abstract
The invention relates to the wine industry, namely to a method for determining the volatile compounds in white wine.The method, according to the invention, comprises the preparation of wine sample by adding ammonium sulfate and 2-heptanol, preliminary preparation of a solid adsorbent of hypercrosslinked polystyrene, placed in a cartridge, by its subsequent treatment with methylene chloride and ethanol, washing with distilled water and blowing with an air stream; adsorption of volatile compounds during passage of sample through the cartridge under vacuum and washing of adsorbent with distilled water; desorption of volatile compounds during passage through the adsorbent of a solvent, consisting of ethyl acetate and methylene chloride in the ratio of 1:1 by volume, by obtaining an eluate, its treatment with anhydrous sodium sulfate, evaporation to the obtaining of a concentrate in the amount of 0.5 ml and determination of volatile compounds by chromatography and mass spectrometry.The result is an increase in the adsorption capacity and number of determined components.
