IEH & Brooks Applied Labs Use Carbon Isotope Analysis to Uncover Vanillin Authenticity Patterns
Together with IEH, Brooks Applied Labs conducted a study evaluating the authenticity of commercial vanilla products using bulk carbon isotope analysis (EA-IRMS) and compound-specific isotope analysis (GC-C-IRMS).
Natural vanillin derived from vanilla beans is one of the most valuable flavor compounds globally and is often subject to adulteration with synthetic or non–bean-derived vanillin. Fifteen products labeled as containing natural vanillin were analyzed in this study. Several samples showed isotopic values inconsistent with vanilla-bean origin.
These results highlight the role of isotope ratio mass spectrometry in detecting economically motivated adulteration and verifying authenticity within the food and flavor industries.

Brooks Applied Labs is moving to a new laboratory facility starting June 20, 2022! At that time, our physical address will change to the following:
On November 9th one of Brooks Applied Labs’ Technical Services staff, Ben Wozniak, spoke at the North American Metals Council – Selenium Working Group on the critical importance of quantitation limits (QLs) when performing analyses for regulatory compliance. Because of variation in how they are defined by regulatory agencies and how laboratories may establish acceptance limits at the QL, best practice is to ensure that the quantitation limit be no more than one-fifth the regulatory compliance level. For example, if a discharge limit is set at 1 µg/L, the laboratory should ideally achieve a quantitation limit of 0.2 µg/L or less in the sample matrix. Doing so will reduce uncertainty in the concentration as it approaches the regulatory limit, so industry and regulators can have greater confidence that any results above the compliance limit are representative and not simply due to method variability.
