Nanotechnology is considered as a key enabling technology by the European
Commission. As a consequence, the European Union’s (EU) regulatory framework covers
nanomaterials explicitly or implicitly. Labelling for the content of engineered nanomaterials
(ENMs) as ingredients in food is mandatory in the EU since December 2014 in accordance
with Reg. 169/2011. Enforcing proper labelling of “nano” poses several analytical
challenges. This includes the many potential sources of nanoparticles in food which can
interfere with the analysis, the challenges in relation to sample preparation, the limitations
of existing analytical techniques and the lack of validated studies and reference materials.
Furthermore, novel food consisting of ENMs requires specific risk assessment (Reg.
2015/2283). In 2011, the European Food Authority (EFSA) published a document which
provides guidance on the risk assessment of the application of nanoscience and
nanotechnologies in the food and feed chain. According to the document, the risk
assessment paradigm, hazard identification and hazard characterization followed by
exposure assessment and risk characterization, is also appropriate for nanomaterials.
Adequate characterization of ENMs is considered essential for establishing the ENM’s
identity and physico-chemical forms in food/feed products and under testing conditions.
One major challenge related to ENMs is their dynamic behavior, meaning that the physicochemical
properties can change in different environments. ENM characterization is
therefore recommend to be performed at five stages: 1) as manufactured (pristine state),
2) as delivered for use in food/feed products, 3) as present in the food/feed matrix, 4) as
used in toxicity testing, and 5) as present in biological fluids and tissues. Stage 3 (in
food/feed) and 5 (in biological fluids and tissues) can be considered as the most
challenging from analytical point of view due to the presence of a complex matrix. The
characterization of the ENM in food/feed and biological samples is, however, of high
importance for exposure assessment and for hazard identification/ characterization,
respectively.
The talk will present examples of analytical challenges and solutions based on DTU
Food’s work with ENMs in food and biological samples. The most frequently used
analytical techniques asymmetric flow field flow fractionation hyphenated with inductively
coupled plasma mass spectrometry (ICP-MS), single particle ICP-MS and electron
microscopy will be introduced and their potentials and limitations highlighted.
The work leading to the presented results has received funding from the European Union
Seventh Framework Programme (FP7/2007-2013) under grant agreements no. 245162
(NanoLyse), 309329 (NanoSolutions) and 604347 (NanoDefine), The Danish Food
Industry Agency (now: The Danish AgriFish Agency) and The Danish Veterinary and Food
Administration.
