Description
Summary:METHODS used for the determination of 2-phenylethanol in fermented beverages have utilized solvent extraction of the beverage or of a distillate, followed by measurements of absorption spectra 1–3 or by gas chromatography 4–8 . The compound is not included in the determination of fusel oils by the colorimetric procedures usually adopted 8,9 . The methods described have certain disadvantages: preliminary extraction may be incomplete unless prolonged, absorption measurements may involve previous purification of the fraction containing 2-phenyl-ethanol, and in the gas chromatographic methods described the retention time of the compound may exceed 1 h with column temperatures above 100°. The method to be described is simple in operation and has been found satisfactory for cider: by the use of a column of low capacity of the type described by Hishta et al. 10 the retention time of 2-phenylethanol has been reduced to 8 min.
