Food colorants are applied in commercial products and domestic cooking to enhance the appearance of food. To obtain specific hues, inorganic food additives containing (nano)particles are mixed in varying concentrations, and pearlescent pigments consisting of mica platelets coated with a layer of titanium dioxide and/or iron oxide particles, are applied to provide glitter effects1 . For assessing potential risks of multi-constituent substances and mixtures, characterisation of the fraction of small particles, including the particle size distribution, is needed for each single constituent or...

Metal content of wine varies from ng/L to mg/L depending on the element. They should be determined and controlled in wines . Indeed, on one hand some of them are of toxicological concern as Lead, Cadmium and Arsenic which are regulated by OIV and by European regulation (CE 1881/2006) ; on the other hand some others can present technological risks as Iron and Copper that may cause precipitations in wines. A new method for metal content in wines was developed by ICP-MS after on-line dilution of the samples. The method was then validated according to the accuracy profile approach. The aim of...

A simple, fast and a robust method for routine speciation analysis of inorganic (Hg2+) and methylmercury (MeHg) by reverse phase (RP) high-performance liquid chromatography coupled to inductively coupled plasma mass spectrometry (HPLC-ICP-MS) was optimized and validated. This novel method is to be applied for the analysis of a large panel of foodstuffs samples within the framework of the 3rd (French) total Diet Study (3rd TDS). TDSs are endorsed by the World Health Organisation (WHO) and Food and Agriculture Organization of the United Nations (FAO) and they are one of the most efficient...

Considering the actual population increase and the compelling need of food waste reduction and nutritional resources saving, former food products (FFPs), not more suitable for human consumption, can be recovered and reused in animal feed as sustainable alternative to cereals. However, some packaging residues (paper, aluminum, plastics etc.) may remain in the final product due to mechanical unpackaging and grinding processes and needed to be quantified and characterized to optimize the use of FFPs and reduce the risks involved. In this work, 14 feeds containing FFPs were taken as part of the...

Trace elements can occur in food because of their presence in the environment, due to human activities or contamination during storage and food processing, including cooking. There are various ways of cooking (boiling, grilling, frying, etc.) and each of them can affect differently the elements' content. This may lead to a decrease or an increase in element concentration, or even to a transformation of the species. Therefore, to better assess people's exposure to these contaminants and avoid or reduce harmful human effects, it is important to know the fate of the elements and their species...

Wold wide, studies have been carried out on the contact of food with stainless steel kitchen utensils and most of them showed a releasing of several metals in "similants" or in a representative food. Kitchen utensils, as unrecognized exposure sources, can cause significant public health risks throughout the developing world. The objective of this study was to investigate the releasing of metals in similants and in some representative foods from artisanal cookwares. We conducted an experimental study on 9 samples of cookware collected in six cookware manufacturing workshops located in...

Chlordecone (CLD) was an organochlorine pesticide frequently used in the French West Indies between 1972 and 1993 to control the banana weevil (Cosmopolites sordidus). The CLD has impregnated the whole ecosystem at all trophic levels, and contaminated the local population through the consumption of locally produced food, raising a major issue of sanitary safety and public health. Self-production is a major route of CLD exposure. These foodstuffs, of vegetal or animal origin, may be consumed by the producer or offered for sale at the roadside and can far exceed the current CLD maximum residue...

Multielement fingerprinting is one of the most widely used technique to discriminate the geographical origin of food. It takes advantage of the fact that mineral elements can be transferred from soil to agricultural products and thus any difference in element distribution between different geographic regions are reflected in agriproducts. The Vesuvian Piennolo Tomato (VPT) is a traditional variety, grown in the Campania (Italy) on the SommaVesuvius volcano slopes, sold assembled in bunches and characterized by long shelf-life. VPT was awarded by Protect Designation Origin (PDO) in 2009....

Wine traceability has become of primary important for consumers as well as for producers. One of the most powerful tools to link wines to their geographical origin is the use of isotopic ratios of three non-traditional elements (Sr, Pb and B) mainly thanks to its very high precision. However, this approach is long and expensive which makes it difficult to use on a daily basis. In this study, a mix of 22 major and trace elements measurable by ICP-MS and proved to be relevant for geographical discrimination purpose have been selected to replace this triple isotopic system. A new method has...

The Joint Laboratories Service is a governmental agency working mainly for the French Customs and the French Fraud Repression administrations. It is constituted of 11 labs, in France mainland and overseas, of different sizes and specialities working together in network. Among this network, the laboratory of Paris is particularly in charge of analysis of various food products to detect some frauds. Those frauds may have for consequences some economic losses for the French administration as well as some consequences on the health safety of population. The purpose of the lecture will be to...
