Ethanol Fraction

Abstract Sake samples are fractionally distilled so that the resultant ethanol concentration of the distillate is approximately 95%. Determination of 14C by liquid scintillation counting on the ethanol fraction differentiates alcohol produced by fermentation from synthetic ethanol produced from fossil fuel sources. 13C/12C stable isotope ratio analysis (SIRA) is capable of detecting alcohol from a cane or corn source in sake samples. This analysis also shows the addition of corn or cane sugar before or after fermentation of the sake.

Ratio Determination

Abstract A method is described for isolating vanillin from vanilla extract, followed by stable isotope ratio analysis to determine the amount of natural vanillin contained in adulterated vanilla extracts. After the potassium content is determined, the percent Madagascar and/or Java vanilla beans incorporated into the extract may then be approximated from the vanillin/ potassium ratio.
