  • Method for determining origin of alcohol or sugar containing products
    Patent number: 9005979
    Abstract: A method for determining origins of food products, and more specifically for determining geographic and/or biological origin of food products containing alcohols or sugars includes preparing an alcohol sample from a product in question, removing exchangeable hydrogen/deuterium atoms from alcohol molecules of the sample, determining the isotopic composition of non-exchangeable hydrogen/deuterium atoms from sample alcohol, and analyzing results for adulteration or determination of product origin. In addition, alcohol ?13C and ?18O isotopic values, along with ?18O isotopic value of the product water are used for the analysis. Products containing sugar are also subjected to tightly controlled fermentation.

  • METHOD FOR DETERMINATION OF DELTA-D VALUES OF NON- EXCHANGEABLE HYDROGEN STABLE ISOTOPES ON ETHANOL' S METHYL GROUP BY MEANS OF IRMS INSTRUMENTAL TECHNIQUE
    Publication number: 20110223629
    Abstract: The present innovation is related with chemical instrumental analysis, i.e. to the domain of analysis of stable isotopes in food products, and it is related to the method for preparation of ethanol samples and mode for determination of isotopic ratio of non-exchangeable hydrogen stable isotopes sited on the methyl site of ethanol by means of instrumental technique CF-TC/EA-IRMS (Continuous Flow-Temperature Conversion/Elemental Analyzer-Isotope Ratio Mass Spectrometry), and for the purpose of establishing authenticity and geographical origin of wine and grape must, beer, alcoholic beverages, fruit juices, honey, vinegars and other food products which contain alcohol and/or fermentable sugars.
