- W2561008091 abstract "Engineered nanoparticles and/or nanomaterials (ENs) could be present in food as ingredients or additives, but also as contaminants from the environment or from food contact materials. Several methods have been developed to detect ENs in simple matrices. However, a number of challenges arise when analysing food and beverages for ENs. In contrast to simple matrices, food has a complex composition, is hetero-dispersed and may contain more than one type of ENs. When analysing ENs in foods, it is therefore of utmost importance to determine in addition to the particle-size distribution the chemical composition as well as the physical and chemical properties of the ENs within the sample. No single technique can provide all relevant information. Therefore, a range of analytical techniques is required for detection and characterisation of nanomaterials in foods. However, many analytical techniques are destructive and therefore a certain sample cannot be analysed twice or by more than one technique. Furthermore, sample preparation methods very often lead to artefacts or changes of the ENs. The nature of ENs can also change over time; e.g., particles could interact to form agglomerates or particles could dissolve. Additional problems arise because it is almost impossible to distinguish between natural and engineered nanomaterials and food-grade reference material is often lacking. In addition, the analytical techniques should be sensitive enough to measure low concentrations, as ENs in a food represent only a small part of the total mass. Furthermore different analytical methods such as SEM, SLS, DLS, BET or hydrodynamic chromatography lead generally to different size distributions and average particle sizes. To illustrate some of the difficulties arising when analysing food for the presence of nanoparticles light scattering techniques were used as an example to analyse simple particle systems." @default.
