Analysis of Organic Marker Compounds and Hazardous Organic Compounds by GC/MS to Identify Contamination, Counterfeiting and Adulteration of Spices
Poster Oct 05, 2016
Food adulteration and counterfeiting continues to grow as a worldwide issue of food safety and economic concern. Spices are one of most commonly adulterated and counterfeited agricultural products in the US. Our previous study determined there were extensive elemental and heavy metals contamination and adulteration in spices. Many of our spice products were identified possibly being highly adulterated or contaminated by metals. In our follow-up Organic study, we focused on the organic markers and toxic organic compounds in our common spices and botanicals (Black Pepper and Cinnamon) in various forms (i.e. spices, teas, condiments and supplements) to determine if these products appeared to be adulterated from an organic compound standpoint as well as an elemental standpoint.

The Use of Pyrolysis/GCMS and Newly Developed Libraries to assist in Characterizing Complex Polymeric SamplesPoster
Pyrolysis-GC/MS is an effective tool in introducing and analyzing polymers. But since the polymer must be broken down to volatile segments in order to be sent to the GC, identification by the Mass Spec does not look at the original polymer, but only the fragments. This poster will look at a unique library designed to work with the existing NIST library, however contains averaged spectra of pyrolyzed polymers so it can be used to directly identify the original polymer sample.READ MORE
