AOAC 2018 Preliminary Program

3:00 pm – 3:30 pm Harvey W. Wiley Award Address: Need for a Comprehensive Approach to Assess Quality of Dietary Supplements • Ikhlas Khan, National Center for Natural Products Research,

• Jian Wang, Canadian Food Inspection Agency (CFIA) UHPLC/ESI Q-Orbitrap Target Screening of ~850 Pesticide Residues in Fruits and Vegetables using Data Independent Acquisition and Compound Database • Kazuaki Iijima, The Institute of Environmental Toxicology Japanese Perspectives on Contaminants Testing in Food and Environmental Samples Using Advanced Analytical Techniques Symposium: Advanced Elemental Analysis Topics Applied to Foods and Pharmaceuticals This session will focus on the application of advanced elemen- tal analysis methods and concepts to elemental contaminants in foods, and elemental analysis methods utilizing the prin- ciples of updated USP methods (232/2232). There will be three speakers, each discussing a different topical issue in the advanced elemental analysis, as well as some flash talks from the best elemental analysis related poster submissions from the conference. Each speaker is from a different background; there will be representatives from domestic and international government as well as industry presenting. Highlighted topics to be covered are nanoparticles and elemental speciation and their application in various matrices. CO-CHAIR: Jenny Nelson, Agilent Technologies, Inc. CO-CHAIR: Kevin Kubachka, U.S. Food and Drug Administration • Sean Conklin, U.S. Food and Drug Administration Arsenic Speciation Analysis in Seafood and Seaweed at FDA • Barbro Kollander, National Food Administration, Sweden Lead Nanoparticles in Game and Arsenic Species in Human Urine: Projects at National Food Agency Sweden • Michael Fricke, Michael Fricke INC The USP <232> Class 1 Element: Arsenic Symposium: Challenges in Rapid Microbiological Method Application Most rapid microbiological methods receive approval and accreditation after extensive development and validation processes. Application of rapid methods within the food industry is complicated by diverse sample matrix complexity and unforeseen analytical challenges presented throughout the production continuum. Food product categories and types for method validation purposes are broadly defined and do not often represent the matrices being tested. Producer’s may have multiple product SKUs within a category and type, however, the various formulations could differentially impact analyte propagation and subsequent diagnostic performance. Products, such as probiotic supplemented beverages, may not only be complicated due to competitive growth of the probiotic strain, but also by flavoring or other ingredients and their effects on method chemistry. Rapid method use can be challenged by unforeseen developments within the industry, such as the implementation and use of phage based process- ing aids for environmental control of Listeria . Many challenges exist to the real-world application of accredited, rapid microbi- ological methods which are often unanticipated and challenge “fit-for-purpose” use paradigms.

University of Mississippi 3:30 pm – 5:00 pm Wiley Award Symposium: Molecular Approaches to Botanical Authentication

This session will complement the Wiley Award Address by Dr. Ikhlas Khan. Dr. Khan has spearheaded efforts to develop and disseminate analytical methods for determination of poten- tially toxic constituents of dietary supplements and to develop and disseminate chromatographic methods for authentication of botanical dietary ingredients in raw materials and finished supplement products. The speakers in the Wiley Award Symposium will describe original approaches to botanical authentication and validation of these approaches. Subjects will include targeted and non-targeted phytochemical finger- printing, DNA authentication, comparison of strengths and weaknesses of the approaches, data interpretation, and determination of reliability for the purpose of botanical authentication. CHAIR: Joseph Betz, National Institutes of Health • Paula Brown, BCIT Chemoanalytical Approaches for Establishing Authenticity of Botanical Products • James Harnly, U.S. Department of Agriculture Targeted and Non-Targeted Phytochemical Fingerprinting for Botanical Authentication • Rahul Pawar, U.S. Food and Drug Administration Complementary Use of Chemical and DNA Barcoding Methods for Assessing the Authenticity of Herbal Dietary Supplements Symposium: Worldwide Perspectives on Contaminants Testing in Food and Environmental Samples Using Advanced Analytical Techniques This session will comprise of world experts who are at the forefront of modern contaminant analysis. The audience will learn about their experiences with utilization of advanced analytical techniques including but not limited to liquid or gas chromatography-high resolution mass spectrometry to identify and quantitate unknown residues in food and environmental matrices. Protocols used in the development and validation of multi-residue will also be presented and discussed. CO-CHAIR: Steven Moser, Oklahoma Department of Agriculture, Food & Forestry CO-CHAIR: Ping Wan, Office of Indiana State Chemist • Amadeo Fernández-Alba, University of Almeria EURL Experiences in Application of LC-HRMS for Pesticide Residues Analysis in Fruits and Vegetables
