“…The fraction of nanoparticulate Ag in relation to the total migrated Ag ranged from below 1% to 69% (Echegoyen & Nerín 2013;von Goetz et al 2013;Ramos et al 2016). Several studies on AgNP-containing polymers did not examine if the observed migration of Ag was due to migration of AgNPs (e.g., Busolo et al 2010;Emamifar et al 2010;Song et al 2011;Bott et al 2014b;Jokar & Abdul Rahman 2014). Only one experimental study that applied a method to detect ENOs (transmission electron microscopy -TEM) described the absence of AgNPs in migrates from AgNP-containing polymer (Ntim et al 2015).…”

“…The large body of literature evidenced dissolution of metal-containing nanoparticles, like Ag (Table 1) and zinc oxide nanoparticles, into ions from FCMs into food/food simulants (Kumar et al 2005;Song et al 2011;Jokar & Abdul Rahman 2014;Ntim et al 2015). Dissolution rate depends on redox potential and surface functionalisation of the ENO as well as ionic strength, temperature and dissolved oxygen level of the surrounding medium.…”

The use of nanomaterials in food-contact applications has created enormous interest in recent years. The potential migration of engineered nano-objects (ENOs) from food-contact materials (FCMs) is one of the most important concerns regarding potential human exposure to ENOs and health risks. Current research focusing on FCMs has often reached inconsistency regarding migration of ENOs. The scope of this critical review is to give a concise overview of the most relevant aspects of the subject, and to identify and discuss the major open questions in relation to migration of ENOs from FCMs. This includes the very fundamental questions whether ENOs can migrate from FCMs at all and what the potential release mechanisms of ENOs could be. The inconsistency of findings from experimental studies is highlighted based on the example of silver nanoparticle migration from polymer-based FCMs. Challenges in the detection and characterisation of ENOs in migration studies and the suitability of the most frequently used analytical techniques are discussed. Further, this review questions the suitability of standard food simulants and migration test conditions for FCMs as well as of conventional mathematical migration models. Considerations regarding the risk for consumers associated with migrating ENOs from FCMs are discussed. ARTICLE HISTORY

“…Song et al (2011) described the migration of ionic silver from polyethylene nanocomposite; migration of silver nanoparticles (seen by SEM-EDX) was found by Huang et al (2011) from polyethylene plastic bags and Echegoyen and Nerín (2013) from both polypropylene food containers and polyethylene plastic bags. The amount of silver migration in those studies was found to be higher in acidic simulants, by increasing temperature and time of contact and by microwave heating compared to a regular oven.…”

Nanotechnology is defined as the study and use of structures between 1 and 100 nm in length (at least in one dimension). Due to the different properties of nanosized materials compared to the bulk material, research in nanotechnology has increased exponentially in recent years. The food sector is no exception, and nanotechnology is present in different stages of the food chain, from agriculture to food processing, supplements, or food packaging. Among them, the most active area of food nanoscience research and development is food packaging.Nanomaterials are used in packaging to improve the packaging barrier properties, to create active or intelligent packaging materials, or to enhance the properties of edible and biodegradable packaging materials. In addition to the packages itself, nanotechnology can also be used in labeling applications, like a nano-barcode. In the present chapter, all these applications and the commercialized products already in the market will be discussed.The current legislation related to nano-developments in food packaging is at different stages in different countries, and there are concerns about the safety of the use of such nanosized materials for food packaging applications. The different studies concerning the possible migration of the nanomaterials used in the packaging to the food will be reviewed.

“…(87) Several atomic spectrometry techniques such as flame atomic absorption spectrometry (FAAS) and electrothermal atomic absorption spectrometry (ETAAS), inductively coupled plasma-atomic emission spectroscopy (ICP-AES), and ICP-MS have been proposed for the determination of the chemical composition of inorganic nanoparticles. (85,88,89) Separation techniques are used to isolate nanoparticles and to determine their size and size distribution. The best known technique for size separation is size exclusion chromatography (SEC).…”

This article discusses the state of the art in the identification and determination of nanoparticles in food. It is 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 nanomaterials within the sample. After a brief description of what nanomaterials are and how to classify them, sources and routes of nanomaterials to food are discussed. The article then follows the debate on legislative consideration, which has emerged very recently. Its main aim is to deliver information on how nanomaterials are determined in food because of the number of challenges that arise when analyzing food and beverages for nanomaterials. No single technique can provide all relevant information. Therefore, a range of analytical techniques is required for detection and characterization of nanomaterials in foods. The principles of the techniques together with their advantages and drawbacks, and reported applications concerning nanoparticles or related nanocompounds are discussed.
