The analysis of the non‐exchangeable hydrogen isotope ratio (δ2Hne) in carbohydrates is
mostly limited to the structural component cellulose, while simple high‐throughput methods …

One of the most common types of adulteration of honey involves the addition of invert sugar
syrups. A new method was developed to measure the stable isotope ratios of carbon and …

The oxygen and hydrogen isotopic composition (δ18O, δ2H) of plant tissues are key tools for
the reconstruction of hydrological and plant physiological processes and may therefore be …

Stable isotopes are commonly utilized for the geographical origin verification of foods,
including wheat. However, assessing processed products poses a greater challenge due to …

The carbon stable isotopic composition, as indicated by the δ 13 C value, of wine ethanol is
inherited from berry sugars, but little is known about the variation in sugar δ 13 C values of …

This study explores the differentiation of sugar and molasses produced from sugar beet and
cane, which are susceptible to fraudulent labeling due to differing production costs. The …

Isotope ratio mass spectrometry (IRMS) measures small differences in the abundances of
light-stable isotopes of elements, mostly carbon, hydrogen, oxygen, sulfur, and nitrogen. The …

An improved procedure for determining 2H/1H isotope ratios, using gas chromatography-
isotope ratio mass spectrometry, has been used to detect the addition of exogenous C4 …

This chapter presents general applications of gas chromatography/mass spectrometry
(GC/MS) for the determination of the authenticity and quality of fruit juices. The contents of …

The stable isotope composition of archived plant material such as leaf wax derived n-
alkanes and tree ring derived cellulose, have proved to be exciting new tools for …
