Event: Food Metrology: Approaches and Tools for Measuring Food Quality

Date: 9 October, 2015 - Location: CNR, Milano, Via Corti 12

@CNRExpoLab experts will provide some examples of #FoodMetrology -based approaches to the detection of food contaminants.

Dr. Giuffrida and Dr. Monaci, from CNR ISPA, Italy, will describe MS-based methods as a multi target screening tool for monitoring allergens contamination in food products. Indeed, EU labelling rules establish that consumers must be provided with comprehensive ingredient information to allow them to easily identify ingredients they need to avoid. Allergen detection in contaminated food is mainly based on immunochemistry techniques, although cross-reactivity and/or by possible epitope masking caused by food processing may complicate detection. MS-based methods for high-specificity and high-sensitivity detection of allergens in foods will be presented.

Dr. Lardy-Fontan, from LNE, France, will describe how metrological measurements contribute to the survey of pharmaceutical residues in water for a better protection of consumers. She will describe multiresidues methods and their importance in the detection of emerging substances, high concern substances and incoming regulatory substances. She will also present examples of metrological design of reference methods in the field of water contamination.

Dr. Salafranca, from EINA - UNIZAR, Spain, will address metrological approaches to assess the migration of contaminants from packaging into food. Illustrative examples of the most challenging studies recently carried out by his research group with multilayer materials will be presented: [1] the determination of non-intentionally added substances (NIAS) from polyurethane adhesives, [2] the profile of volatile radiolysis compounds formed as a consequence of gamma-irradiation of multilayers and [3] the contamination due to the transfer of substances from printing inks (set-off) from the outer to the inner layers, intended for direct contact with food.

Dr. Bigini, from Istituto Mario Negri, Italy, will present metrological strategies applied to high throughput screening of toxic effects of Titanium dioxide nano-particles on gastrointestinal tract. In the last years several works have pinpoint the dangerous role of the ingestion TiO2 nano-particles, a common food additive used for whitening foods, but its real impact is still far from being elucidated. Dr. Bigini will report on the generation of an integrated platform to evaluate the interaction between TiO2 nanoparticles and biological matrices at increasing levels of complexity.
