“…This paper discusses how the "bomb" 14 C content can be used as a tracer to make inferences concerning the age of sources of contemporary food raw materials processed by various commodity industries. Previous studies (Martin et al, 1983(Martin et al, , 1985 have employed 14 C content to identify fossil fuel-based additives to alcoholic beverages.…”

“Post-maximum-bomb” 14C activities (1964 to the present) provide a natural isotopic signature to obtain information on biomass source age in contemporary food preparations. An analysis of the 14C content in frozen orange juice-containing products purchased in 1996 suggested, in one case, an inferred growth period between 1992 and 1994 for oranges used in the preparation of this commodity. In another case, the 14C analysis indicated an inferred average growth period of 1988−90 for the organics in a “frozen concentrated enriched citrus beverage”. The presence of significant amounts of chemical additives obtained or synthesized from fossil carbon sources can also be documented by measuring 14C content. Keywords: Radiocarbon; carbon isotopes; orange juice; component age

Allyl isothiocyanate is the major component of the mustard oil. This molecule can be synthesized at a much lower price than its cost when extracted from mustard seeds. Adulteration of natural mustard oil by adding synthetic allyl isothiocyanate is therefore very profitable. In order to detect such a fraud, a new analytical approach has been developed using both SNIF-NMR (site-specific natural isotope fractionation studied by nuclear magnetic resonance) and IRMS (isotopic ratio mass spectrometry). This approach enables an unambiguous distinction between natural and synthetic allyl isothiocyanate. It also makes it possible to identify the geographical origin of natural mustard oils. The principle of the interpretation is based on a multivariate analysis of the isotopic parameters of allyl isothiocyanate, (D/H) i , δ13C, δ15N, and δ34S, which provide largely independent information. The discriminating performances of the different isotopes are discussed. Keywords: Allyl isothiocyanate; mustard oil; SNIF-NMR; 13C-, 15N-, 34S-IRMS; authentication; adulteration; geographical origin
