AOAC 2017 Annual Meeting Preliminary Program

TUESDAY, SEPTEMBER 26, 2017 8:15 AM – 9:45 AM

the food industry’s perspective will also be part of the discussion, as well as the latest results of the iFAAM ring trial that give an overview of the current capabilities of analytical methods. The discussion will also cover the advantages and disadvantages of immunological and mass spectrometry based methods and give an outlook of considerations for future approaches. CO-CHAIR: Carmen Diaz-Amigo, FOCOS GbR CO-CHAIR: Gavin O’Connor, European Commission – Joint Research Centre • Bert Pöpping, FOCOS GbR The History (and Future) of Allergen Labeling Regulations: These Could be Simple, but we Insist on Making them Complicated • Kurt Brunner, ROMER Labs Division Holding GmbH Immunological Methods for Allergen Detection: Challenges and How to Deal with them • Clare Mills, University of Manchester Analysis of Allergens in Foods in a Risk Assessment Context: The role of Immunoassay and MS Methods • Prabhakar Kasturi, PepsiCo Inc. Practical Considerations about Food Allergen Testing from an Industry Perspective Characterization of Botanical Extracts Using Multiple Technologies Most commercially available Botanical Reference Materials (BRMs) used for identity testing are botanicals in their original form (leaf, root, seed, etc.). This can present problems when BRMs are used to verify the identity of botanical extracts, which may or may not have a similar profile to the unprocessed botanical. For proper identification of botanical extracts, Botanical Extract Reference Standards are needed. Whereas powdered botanicals typically retain most of the chemical constituents found in the original plant material due to light processing (e.g., grinding), botanical extracts undergo complex and vigorous processing (such as solvent extraction, fractionation, distillation, fermentation, addition of excipients, etc.) which can cause significant changes in the chemical profile. Scientists tasked with verifying the identity of botanical extracts must understand how processing steps can affect the composition of an extract reference material, as well as understand which reference materials are appropriate for use for each sample. This session is intended to cover the important considerations for characterization of botanical extracts by assessing their unique profiles. Various technologies are available for characterization of the chemical components in botanical extracts, including HPTLC and HPLC checking the chromatographic profile with separation, and NMR analyzing the spectroscopic profile, LC-MS combining the physical separation capabilities of liquid chromatography with the mass analysis capabilities of mass spectrometry. All these considerations need to be addressing during full characterization of botanical extracts with different technologies. This session proposes to cover this topic by scientists with expertise in different techniques.

New Blood 2017: Developing Methods for the Detection of Chemical Residues, Contaminants and Important Analytes The detection of chemical analytes, residues, and contaminants in consumer commodities and the environment is an interesting, challenging, and continually evolving discipline. In order to maintain a vibrant and active Chemical Contaminants community in AOAC, young scientists must be encouraged to work in these areas. The purpose of this session is to provide new members of our community an opportunity to present their work for the first time at a technical session at the AOAC Annual Meeting. The presentations in this session represent the broad interests of the AOAC Chemical Contaminants Community that emphasize the analysis of pesticide and veterinary drug residues, environmental and industrial contaminants, adulterants, natural toxins, and other important chemicals or issues in food, feed, environmental samples and other relevant matrices. It is hopeful to continue the tradition to have a New Blood session at every AOAC meeting dedicated to new and talented AOAC scientists, stakeholders, and members.

Regulations are very diverse with few regulated thresholds, making it challenging to interpret results “correctly”. Test kit manufacturers aim to develop analytical methods that meet the demands of the food industry. As this industry has diverse needs, a one-for-all solution is not achievable. On the other hand, academic research is focusing on food allergen mass spectrometry methods which are typically not suitable for the inevitable in-process testing in food production environments. This session will link these different aspects of food allergen management and explain the challenges each party faces. An overview about the history of allergen legislation sheds light on the different regulations that apply and why it is so difficult to find common and detailed rules. The lack of allergen threshold levels is not only a challenge for the food industry, but also for test kit manufacturers who need to ensure that their testing solutions are compatible with the indefinite range of applications. Close cooperation between the food producer and the test kit supplier is crucial to achieve the required high level of food safety. Specific demands and real-life experiences from
