Carbon, Nitrogen and Oxygen Stable Isotope Ratios in Chitin
2010Stable isotope ratios in chitin are firmly imprinted during biopolymer biosynthesis and reflect dietary, metabolic, and environmental influences. Chitin is a chemically complex amino sugar biopolymer that also includes non-amino-sugar moieties with contrasting isotopic compositions.

Stable nitrogen isotopic composition of wine: a preliminary investigation
2013The 15N/14N ratio has been measured in several foods to trace geographical origin and agricultural systems, but not yet in wine. In this work we developed a method for measuring 15N/14N in bulk wine, following dealcoholisation and dehydration. The δ15N of wine did not change after freeze-drying the sample or evaporating it under vacuum, obtaining ...
