Usage of nanotechnology in food with all of its possible different applications has potential to significantly change today's ways of food manufacturing and packaging as well as to alter fundamental functionality of food. Application of nanotechnology in food increases food safety, allows better delivery of new functional ingredients and extends product life. Food nanotechnology implies nanotechnology application in food package manufacturing and nanotechnology application directly to food products. Production of nanopackages implies usage of nanosensors for detection of contaminants and pathogens, nanosensors for product tracking and control, nanoparticles for improvement of mechanical properties and biodisintegration of a package. New food ingredients in food can be delivered by means of colloids, liposomes, nanoemulsions or nanolaminats, thus transforming food products into health preparation or a medicine. Increased research in the field of nanofood application and a possible nanofood mass production can perhaps lead to health risk for consumers; hence it is important to pass new scientifically based regulations which will define usage of food nanotechnology.

A method to validate the relevance of the Total Diet Study (TDS) approach for different types of substances is described. As a first step, a list of >2800 chemicals classified into eight main groups of relevance for food safety (natural components, environmental contaminants, substances intentionally added to foods, residues, naturally occurring contaminants, process contaminants, contaminants from packaging and food contact materials, other substances) has been established. The appropriateness of the TDS approach for the different substance groups has then been considered with regard to the three essential principles of a TDS: representativeness of the whole diet, pooling of foods and food analyzed as consumed. Four criteria were considered for that purpose (i) the substance has to be present in a significant part of the diet or predominantly present in specific food groups, (ii) a robust analytical method has to be available to determine it in potential contributors to the dietary exposure of the population, and (iii) the dilution impact of pooling and (iv) the impact of everyday food preparation methods on the concentration of the substance are assessed. For most of the substances the TDS approach appeared to be relevant and any precautions to be taken are outlined. © 2014 Elsevier Ltd. Source

The objective of this article is to develop a general method based on the analytic hierarchy process (AHP) methodology to rank the substances to be studied in a Total Diet Studies (TDS). This method was tested for different substances and groups of substances (N = 113), for which the TDS approach has been considered relevant. This work was performed by a group of 7 experts from different European countries representing their institutes, which are involved in the TDS EXPOSURE project. The AHP methodology is based on a score system taking into account experts' judgments quantified assigning comparative scores to the different identified issues. Hence, the 10 substances of highest interest in the framework of a TDS are trace elements (methylmercury, cadmium, inorganic arsenic, lead, aluminum, inorganic mercury), dioxins, furans and polychlorinated biphenyls (PCBs), and some additives (sulfites and nitrites). The priority list depends on both the national situation (geographical variations, consumer concern, etc.) and the availability of data. Thus, the list depends on the objectives of the TDS and on reachable analytical performances. Moreover, such a list is highly variable with time and new data (e.g. social context, vulnerable population groups, emerging substances, new toxicological data or health-based guidance values). © 2014 Elsevier Ltd.
