AOAC 133rd Annual Meeting - Final Program

Scientific Sessions | Tuesday

10:30 AM Miniaturized NIR Detectors Hertzstück™ for Mobile Food Fraud Detection and Quality Assurance Wilfried Hermes, Trinamix TrinamiX presents its miniaturized NIR spectrometer technology for wavelength from 1– 3 µm. The wavelength range covers the complete NIR fingerprint of organic materials. This enables new, smart applications, e.g. spectrometers in kitchen and household appliances, in agriculture, food process- ing and in food quality assurance and fraud detection. Making handheld spectrometers available to everyone, the laboratory will come to the sample and no longer the sample into the laboratory. 10:45 AM Sandra Salleres, Arrate Jaureguibeitia, BiolanMB Histamine intoxication is among the most common toxicities related to fish ingestion and results from the consumption of inadequately preserved and improperly refrigerated fish and it resembles an allergic reaction. At high concentrations (above 200-500 mg/kg) histamine is toxic and leads to symptoms similar to severe allergic reactions. For products containing fish species with high amounts of histamine, a limit of 200 mg/ kg has been established by the Commission Regulation (EU) 2019/229 of 7 February 2019 amending Regulation (EC) No 2073/2005. Today there is a great concern about food fraud related to tuna intended for canning being sold as fresh. The food fraud consists in the application of vegetable extracts containing nitrite solu- tions to change the color of tuna, which is an illegal practice due to inappropriate freezing (EC 853/2004), change of color of fish (EC 1333/2008) and treatment of fish (EC 1333/2008). This practice is particularly dangerous as non-fresh fish is eaten raw and may contain high levels of histamine that can cause food poisoning. Information about the notifications concerning histamine contam- ination in tuna covering the period 2014-2017 showed an evident rise of notifications with a sharp increase in the second quarter of 2017. 11:00 AM The Potential to Utilize Portable Handheld XRF (X-Ray Fluorescence) for the Elemental Analysis of Soil, Fertilizer, Animal Feeds and Foodstuffs Mark Lessard, Paul Dewsbury, Thermo Fisher Scientific The performance levels of hand held XRF spectrometers has increased significantly in just the last few years. This Portable Enzymatic Biosensors: From Laboratory to Market. Case Study: Tuna Fraud Detection

easy-to-operate (minimum amount of training required) tech- nology has the ability to analyze elements on the periodic table starting with Mg (Magnesium) up to U (Uranium). Based on Energy Dispersive X-Ray Spectroscopy, these analyz- ers can measure simultaneously up to 40 elements down to single digit ppm (parts per million) limits of detection within a 30 second total analysis time. As a screening tool this rapid/ high-throughput technology can be a complimentary tool to the more traditional laboratory-based spectroscopies. Handheld XRF has the potential to assist in uncovering food fraud including detection of contaminations and validating authenticity to insure food integrity. This presentation will explain how handheld Energy Dispersive XRF technology works, demonstrate achievable performance levels and highlight potential food applications. The author is interested in learning from the audience about potential appli- cations including sample type/matrix, elements of interest and levels of detection required. 11:15 AM Isothermal, On-Site Food Authenticity Detection Gianpaolo Rando, SwissDeCode Food mislabeling or cross-contamination can take place at multi- ple steps in the food value chain: during manufacturing process, but also upstream and downstream. Naïve or intentional, those mistakes can result in losses for businesses or even health issues for consumers. Food production works with tight and fast processes: waiting for laboratory results it is not always possible, and this leaves brands and companies vulnerable to fraud. In this talk, we will discuss case studies in the dairy, grain, and animal feed industry in which rapid results from DNA analyses helped companies to improve their operations, to defend their brand or to launch new products faster than the competition. 11:30 AM Putting Disruptive Technologies into Context: How Miniaturization Will Change the way Food Industry Will Deal with Food Fraud and Quality Control Bert Popping, Carmen Diaz-Amigo, FOCOS Food Consulting Strategically The global food safety testing, inspection and certification (TIC) market is predicted to grow significantly over the coming years to more than $250 billion USD by 2024. While until recently, tests were almost exclusively performed in laboratories, new and disruptive mobile testing technologies are likely to reverse some of this. These technologies will not only be used for incoming raw materials checks but will also be useful for inspections by governments and private party schemes, thereby impacting at minimum two of the elements of the TIC market. The session will provide an overview of some of the emerging technologies that can be used to detect food fraud using mobile devices. This presentation will put these developments in the context of the changing paradigms of the TIC market.
