This work presents a method that can be used for detection of very low levels of BPA in canned broth. Careful testing of blank samples, mobile phase and LC system components are recommended to circumvent BPA laboratory background. The method uses molecularly imprinted polymer SPE to extract and pre-concentrate BPA. The background BPA levels in this study were found to be below 0.2 ng/mL in the final sample. Analysis was performed using LC with fluorescence detection. Recovery of BPA from chicken broth spiked to 60 ng/mL was 72.5%. Recovery of BPA from beef broth spiked at 5 ng/mL was 75%. Another unfortified sample of beef broth was analyzed and found to contain BPA at levels greater than 60 ng/mL.
Concern about the safety of food products has increased dramatically with intentionally and non-intentionally added substances (NIAS) used in packaging being of particular interest. APGC and high resolution MS together with a workflow driven process was used to identify unknown compounds in packaging.READ MORE
In April 2017, a campus-community event (N=42 participants) was held to promote sustainable food systems by educating participants about concepts ranging from food production to nutrition and food waste management. This poster discusses the resulting increased awareness and knowledge of a our local food system among participants, which can be fostered through educational events that combine opportunities for research, teaching, and practice.READ MORE
