“…The term C 4 -plants is derived from four C-atoms of the oxalacetate, the photosynthetic product of the phosphoenolpyruvate-carboxylase reaction. Due to a smaller isotope effect more 13 C is less depleted than in C 3 -plants. The best known C 4 plants are sugar cane, corn, or millet.…”

“…In the same way, however more surging, the (D/H) I -ratio increases by use of cane sugar. Mixtures of beet and cane sugar may compensate each other but by additional 13 C-IRMS analysis the cane sugar component will be detected nevertheless. Therefore it is always advisable to determine both the (D/H) I -and δ 13 Cvalue of wine ethanol [13,14].…”

“…This has led to the decision that only L-tartaric acid extracted from grapes as a lawful mean for acidification. IRMS analysis of the isotope ratios of 18 O and 13 C is a suitable technique for distinguishing natural and synthetic L-tartaric acid. Even the geographical origin and year of production of the natural tartaric acid can be identified [22].…”

“…The recognition of stable isotopes as genuine markers of food was a milestone of improved food authentication. Stable Isotope Ratio Analysis (SIRA) of the bio-elements 2 H, 13 C, and 18 O in biomolecules of food started already in early Seventies [1,2]. One important breakthrough in authentication was the development of an analytical method based on Deuterium-Nuclear Magnetic Resonance ( 2 H-NMR) also known as SNIF-NMR ® -Method [3].…”

Abstract. The implementation of stable isotope applications in official food analyses began in 1990. At that time the first method to detect sucrose from sugar beet or sugar cane in wine by Deuterium-Nuclear Magnetic Resonance ( 2 H-NMR) of ethanol, also known as SNIF-NMR ® -Method became adopted officially by the European Commission. This was a milestone for an improved authentication of wines and other food stuffs. In connection with methods using Isotope Ratio Mass Spectrometry (IRMS), stable isotope ratio analysis is one of the most powerful analytical tools for authentication of wine. The fundamentals of biotic and abiotic stable isotope fractionation and the analytical methods which are used in authentication of wine are summarized. Principles of authentication of some wine constituents like sugar, ethanol, organic acids, glycerol, and carbon dioxide as well as proof of geographic origin are reviewed. By selected example of anonymized cases, proof of adulterations (e.g. chaptalization, addition of water or mislabeling) using monovariate, bivariate, and multivariate data evaluations are discussed. It is shown that for this purpose databanks are generally indispensable. In their absence cut-off values, derived from long-term observations help to detect clear adulterations.

The isotope ratios of ethanol, an important constituent or ingredient of some foods and various beverages and fuels, provide information about biological and geographical origin and quality. We have developed an improved method for measuring the isotope ratio of ethanol in various samples by gas chromatography-high temperature conversion or combustion-isotope ratio mass spectrometry (GC-TC/C-IRMS) with headspace solid-phase microextraction (HS-SPME). A HS-SPME method was developed by optimizing several different parameters, including salt addition, incubation temperature and time, and extraction time. The HS-SPME method enabled us to determine the isotope ratio at low ethanol concentrations (0.08 mM) in 50 min with good precision (+/-0.3 per thousand for delta(13)C and +/-5 per thousand for deltaD). An advantage of this technique is that it can be adapted for use with samples which have high viscosity and contain many matrix compounds, such as alcoholic and non-alcoholic beverages.

Control of origin of larch wood: discrimination between European (Austrian) and Siberian origin by stable isotope analysis

Most of the coniferous wood of non-European origin that is imported into the European Union (EU) has to be inspected phytosanitarily, to prevent the introduction and spread of harmful pests in EU territory. Wood importers have been caught declaring Siberian larch wood as being of European origin to save the costs of the inspection. Therefore, an unequivocal method has to be developed in addition to the traditional analysis of the tree ring density to identify incorrect declarations of larch wood origin. For this purpose, delta18O and delta13C analyses have been carried out to check if Siberian larch wood can be discriminated from European larch. Measurements have been carried out on bulk wood samples, as the method has to be designed to be as simple as possible. The results show an overlapping of the Siberian and Austrian delta13C, and no overlapping for the delta18O values.
