Authentication of a food product is the procedure by which it is verified that the product
matches the statements on the label, and that it conforms to what is established by …

In this review, we examine the variation in stable isotope signatures of the lighter elements
(δ2H, δ13C, δ15N, δ18O, and δ34S) of tissues and excreta of domesticated animals, the …

The aim of this study was to use proximate chemical composition, macro and trace elements,
fatty acid profile and stable isotopes as traceability tools to assess geographic origin and …

We compared δ13C and δ15N ratios of barn-raised and free-range chickens to determine if
differences in their diets were reflected in the stable isotope composition of their tissues. We …

This study examined variations in the Fulton condition factor, chemical composition, and
stable isotopes of carbon and nitrogen in the Brazilian freshwater fish cachara …

Techniques to trace geographical origins and production methods are still scarce and not
routinely applied by food safety authorities. The aim of this study was to assess the …

The rise of processed seafood in international trade has increased the feasibility of fish
species substitution. Gadidae fish species are sold commercially as salted fish, and …

Studies on the detection of animal by-products in poultry meat are rare and practically
nonexistent in chicken meat. With the development of the technique of stable isotopes for …

The aim of this study was to trace the inclusion of animal meals in layer diets by analyzing
eggs and their fractions (yolk and albumen) using the technique of carbon and nitrogen …

The objective of this work was to evaluate carbon turnover and half-life in feces and blood
from sheep fed on C3 and C4 plant diets, using the stable isotope technique. Eight Santa …
