Safety issues when using carbon dating - mammoth carbon dating

If a company suspects curcumin may be adulterated, confirming that fact is no easy task, however, because many test methods, including DNA testing, cannot differentiate synthetic and natural curcumin.And that’s because adulterers have gotten very good at mimicking the real thing.

Instead, some curcumin suppliers are now turning to radiocarbon dating.Synthetic curcumin, which is created using petrochemicals/fossil fuel, does not contain carbon 14.Using carbon dating (C14 testing) via methods like accelerator mass spectrometry, analysts look for the presence of carbon 14 to confirm that an ingredient is, in fact, from a natural source.This standard mixture is commonly known in the industry as “curcumin 95%.” When natural curcumin is tested using high-performance liquid chromatography (HPLC), these three curcuminoids register as specific peaks.The problem is that adulterers are now able to create synthetic curcumin that will also register these same three peaks.“Natural turmeric-derived samples usually contain a mixture of curcumin (about 75%–80%), demethoxycurcumin (about 15%–20%), and didemethoxycurcumin—also known as bisdemethoxycurcumin (below 5%),” Rafi explained in the Bioactives white paper.

Together, these three curcuminoids comprise curcumin’s key active constituents.According to Sabinsa, several commercial labs have adopted the test method.Beware Synthetic What’s the harm in synthetic curcumin?Natural curcumin extracts contain carbon 14, a radioactive isotope of carbon.Plants naturally contain carbon 14 (also called simply “radiocarbon”) because it is part of the carbon dioxide that plants take in from the atmosphere during photosynthesis.Rafi, Ph D, founder and CEO of curcumin supplier Bioactives American Corp. According to Rafi, the problem with curcumin adulteration has been growing since around 2010 when there was a shortage in curcumin supply.
