AN 22 - Combustion Module-CRDS for δ13C analysis of imported honey and detection of adulteration
A fast screening method of imported honey to test for product adulteration with high fructose corn syrup.
Natural products may have divergent stable isotope compositions based on a variety of factors. These stable isotopic compositions create a measurable isotopic signature for a certain botanical class. Carbon isotope ratio analysis is a well-known tool used to detect food adulteration by comparing botanical isotopic signatures. The stable carbon isotope value, δ13C, is very sensitive to plant type. Scientists have not used this value to its full extent to detect food adulteration due to the considerable difficulty, time and cost of obtaining δ13C data using traditional IRMS instrumentation.
