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 δ13C and δ18O isotopic values, along with δ18O isotopic value of the product water are used for the analysis. Products containing sugar are also subjected to tightly controlled fermentation.
Claims22
A process for determining origin of a food product containing alcohols or sugars, comprising:
- preparing an alcohol sample from the food product;
- at least partly converting the alcohol sample into an olefin;
- measuring an isotopic composition, i.e., isotopic relative ratio of hydrogen and deuterium of the olefin;
- and
- comparing measured isotopic composition of the olefin with known isotopic compositions of olefins from food products with known origins.
A process for determining origin of a product containing alcohols or sugars, comprising:
- preparing an alcohol sample from the food product;
- at least partly converting the alcohol sample into an acetaldehyde;
- measuring an isotopic composition, i.e., isotopic relative ratio of hydrogen and deuterium of the acetaldehyde;
- and
- comparing measured isotopic composition of the acetaldehyde with known isotopic compositions of acetaldehyde from products with known origins.
