ISO 17025-accredited Beta Analytic presented the results of its garlic oil case study in an article published in the Journal of Agricultural and Food Chemistry. The lab tested five commercially available garlic oil — four were labeled as “natural” and one sample was clearly labeled as “artificial”. All five samples passed GC-MS testing. However, Carbon-14 analysis results show that only one of them is 100% naturally sourced.
Carbon-14 testing enhances the quality control measures of essential oils manufacturers and distributors.
There are several analytical techniques used to detect adulteration in natural products like essential oils. However, these methods only detect “natural” adulterants often in combination with other tests. Carbon-14 analysis can detect synthetic, petroleum-derived adulterants. The method, however, cannot identify specific adulterants.
