Ljubljana, 9 – 13 April 2018
The Spring School and Workshop are dedicated to various perspectives of nanoparticles in food: either they may appear in food during production, packaging or cooking, or they are introduced to enrich taste, colour or consistency. As they are very small, they are difficult to detect in food, and require special techniques to characterise and analyse their interaction with cells and possible effect on human health.
The three-day Spring School will provide participants with the basic knowledge connected to these topics, while during the following two-day Workshop participants will get to know about selected techniques for nanoparticle detection and characterisation. Intense discussions and training by internationally renowned scientists in the field are planned. The training will be spiced up with everyday examples.
We invite participants from a broad area connected with food to attend both the Spring School and Workshop, however, attendance of only one or the other is also welcome.
Participation in the two events will be enriched by social events, giving the participants not only the opportunity for informal gathering with researchers from various fields but also to experience Ljubljana city, the boat trip and to taste the Slovenian cuisine.
Participation at the Spring school and workshop is free of charge, however, participants have to cover their own expenses of travel and accommodation.
Venue: Jožef Stefan Institute, Jamova cesta 39, Ljubljana, Slovenia

ISO-FOOD: Isotopic techniques in food safety, quality and traceability
Virtual Special Issue
The past few years has seen a resurgence in the need for and development of new methods and techniques for assuring the quality and safety of food. Much of this comes on the back of major food scandals, continued globalisation and complexity of the food supply chain, new threats (e.g., nanotechnology), advances in instrumentation (especially Mass Spectrometry) and a shifting definition of how we define food quality. The ERA Chair ISO-FOOD as guest editor of this special issue invites people to submit original research and critical reviews on the use of isotopic techniques relating to food safety and quality. Although ISO-FOOD has a bias towards the use of Isotopes in authenticity and traceability we will consider submissions on essential and nonessential elements and their speciation, organic contaminant and important bioactive compounds in food and articles on the exploitation of big data in relation to food chemistry as long as they conform to the scope of FOOD Chemistry.
Interests: Isotopic techniques; Authenticity; Adulteration; Traceability; Safety, Mass spectrometry, NMR techniques; Chemometrics, Modeling
Manuscript Preparation and Submission
All manuscripts must be submitted through the online submission system (EES) of Food Chemistry. To ensure that all manuscripts are correctly identified for inclusion into the special issue, it is important to select “VSI: ISO-FOOD” when you reach the “Article Type” step in the submission process. Please refer to the journal’s Guide for Authors for specific advice on how to prepare a paper (http://www.elsevier.com/locate/foodchem). All papers will be evaluated by the Guest Editors and then reviewed by at least two reviewers. Accepted papers are published online individually as ‘Articles in Press’ after final acceptance, and before final print publication.
Special issue Timelines
- • January 1, 2018: EES will be open for submission
- • April 30, 2018: Deadline for submission
- • January 2018 – November 2018: Period of peer-review process

The Summer School included theory and two days of hands-on experience in the laboratory. Understanding elemental speciation requires robust analytical methods with well-established methodologies for analysing food. The course addressed this by providing participants with an in-depth knowledge of trace element speciation using examples of essential and non-essential elements including Cr, Zn, Ni, Hg and As to teach and demonstrate the state-of-the art analytical approaches to the problem of trace element speciation. The lectures also covered the topic of nanoparticle residues in food. In total forty-five participants representing academia, industry and governmental and non-governmental organizations attended this free event.
Presentations (in Slovene) are available:

Bisphenol A (known as BPA) is a synthetic organic compound found in polycarbonate plastics and epoxy resins. Polycarbonate plastics have many applications including in the food industry in water bottles, food-storage containers, and plastic tableware. Epoxy lacquers are used as linings in many metal products such as food can, bottle tops, lids of glass jars for baby food, pickles, jam, honey, salsa and other condiments, aerosol cans for whipped toppings and non-stick sprays, bottles and tins of cooking oil, aluminium beverage cans, metal coffee cans and beer kegs. When taking into consideration the myriad of non-food applications, it is no wonder that BPA has become ubiquitous in modern-day life and impossible to avoid. The cause for concern is that BPA is a known endocrine disruptor and years of animal testing has linked BPA with neurological and behavioural disorders, reproductive disorders such early onset of puberty and a rise in prostate and breast cancer, cardiovascular diseases, obesity and diabetes. As a precaution, the EU in 2012 banned its application in baby bottles and sippy cups although in 2015 the EU rescinded the ban after the European Food Safety Authority (EFSA) re-evaluated BPA exposure and toxicity. Several EU nation states, including Austria, Belgium, Denmark, France and Sweden, despite the EFSA ruling, continue to regulate BPA more strictly. The food industry has responded to consumer concerns and “BPA-free” products are commonplace. Despite this, “BPA free” does not mean “bisphenol-free”. Many alternatives to BPA, such as BPS and other similar compounds found in plastics have just as potent, if not more potent, hormone mimicking effects as BPA and scientists are only now beginning to investigate the risk posed by these compounds. In a new study by Česen et al., (2016), published in the journal of Agriculture and Food Chemistry, the authors examine the occurrence of bisphenols and related compounds in honey and their migration from selected food contact materials. The authors chose honey because it is a highly prized food commodity, cherished for its quality, purity and taste. The authors also noted how honey comes in many different types of packaging, which could put the honey at risk from potentially harmful migrating compounds. Their paper describes the development of a single method to analyse nine bisphenols (BPA, BPAF, BPAP, BPB, BPC, BPE, BPF, BPS, and BPZ) and related compounds (4-cumylphenol and dihydroxybenzophenone) in honey samples and food simulant. The authors used their method to analyse honey from European and non-European countries and food simulant stored in different packaging. The majority of samples contained bisphenol residues and the highest number of bisphenol compounds determined in any one sample was four. Only BPA and BPAF were found during migration tests and in glass jars with epoxy lined metal lids and in laminated sachets. Based on the exposure from observed maximum levels of BPA in honey, there is little risk to consumer health (exposure < TDI 4 μg/kg bw/day), although the authors’ emphasise that cumulative health effects of the identified bisphenols should be further explored. The authors also show how some of the contamination derives from a source other than the final packaging. Retailers could use this data to pass on recommendations to honey producers with respect to the use of suitable food contact materials along the honey value chain.
