Saffron, the dehydrated red stigmas of the plant Crocus sativus L., being the most expensive spice worldwide, is a potential target of fraud or mislabelling. So far, determination of the levels of the major water-soluble and volatile saffron compounds has been exploited for geographical differentiation or quality control purposes. The elemental profile of foods and especially REE one, which constitutes also a powerful tool for traceability, as well as for geographical origin demonstration, reflecting soil characteristics, area of production and environmental growing conditions, is not yet...

Geographical origin assignment of food products often requires multi-element stable isotope analyses combined with the multi-elemental profiles and multivariate data evaluation. We introduced a new analytical approach consisting of a combination of elemental characteristics, Pb and Sr isotope information in terms of establish a new tool to differentiate geographical provenance of wine. This method has been successfully approved on high value Bordeaux Grand Cru wine the authentique wine and counterfeits made of this brand were recognized. More than a hundred samples of Bordeaux wines, wines...

Presence of unregulated and not assessed organic microcontaminants such as pharmaceuticals and personal care products (PPCPs) in wastewater effluents represents a significant challenge to wastewater reclamation, especially if intended for human consumption or irrigation practices. It is widely accepted that due to the insufficient treatments for PPCPs at WWTPs, certain fractions of these contaminants are discharged in effluents and then are introduced into agroecosystems through land application of manure and biosolids, as well as crop irrigation with reclaimed water. The uptake and...

An analytical method was developed to measure δ 13 C, and for the first time, δ 2 H of fatty acid methyl esters (FAMEs) extracted from olive oil triglycerides, after base-catalysed transesterification with methanol. FAMEs are analysed using Gas Chromatography Combustion/Pyrolysis Isotope Ratio Mass Spectrometry (GCC/Py-IRMS). Accuracy, precision and uncertainty of the whole method (from preparation to measurement) were determined as well as the impact of methylation on δ 13 C and δ 2 H. The obtained performance of the method is satisfying and allow the determination of reliable data.

Spectroscopic/spectrometric analyses of spices offer low-cost, rapid measurements for qualitative and quantitative purposes related with authenticity, traceability and quality issues. To get most of the information encoded in the spectral data about the composition of a sample, metabolic fingerprinting approaches and/or chemometric methods are frequently applied. However, these approaches require the building up and use of “fit- to-purpose” databases with special precaution on the reliability of the sample meta-data. The latter may refer to botanical and geographical origin, harvest time,...

In the last few years, Fourier transform infrared (FTIR) spectroscopy has significantly advanced in biological research. This has been due to recent progress in the use of chemometrics, such as partial least square (PLS) analysis or principal component analysis (PCA) for the extraction of reliable information even from highly complex FTIR spectroscopy spectra. In comparison to conventional chemical analyses, FTIR spectroscopy has striking advantages due to the high reliability, sensitivity, and the speed of measurement procedure. Here we present some preliminary data on the use of Fourier...

Attenuated Total Reflectance/Fourrier Transform Infra Red (ATR/FTIR) Spectroscopy is a powerful technique for the rapid extraction of information from complex matrices such as the composite films that are based on edible biopolymers. These films are used for the protection of food products against moisture uptake and are consumed with them. In order to be suitable for food packaging they need to be stable against physical and chemical changes upon storage. FTIR is a convenient tool to examine the film compounds and changes due to their interactions during ageing. However, the incorporation...

Published literature in food authenticity studies is based on multivariate chemometric models that have been calibrated under controlled conditions using a limited dataset and a particular spectral acquisition instrument. There is a challenge to create accurate and robust chemometric models that would be able to perform well when tested with samples that have never been encountered by the calibration data and be applicable when the acquisition instrument is different from the initial instrument. Augmentation of the models with synthetic samples is a fresh approach to overcome these...

Several thousands of chemical substances which are used in the production of food contact materials and articles have the potential to migrate into foods. It needs high analytical experience, hard work and high level instrumentation to determine the level of their migration into foods or food simulants. Development of multi-analyte methods is necessary in order to cope with the huge number of chemical compounds which should be determined. Application for the official control necessitates validation for each combination of analyte/substrate/simulant/migration condition. A very promising...

In the food sector, applications of nanotechnologies to (i) agricultural production, (ii) food processing, and (iii) food contact materials are rapidly developing. An appropriate nano-specific risk assessment has to be carried out for nanotechnology applications that result in the presence of nanoparticles in food. One essential issue in such an assessment is to ascertain whether there is potential for systemic exposure, i.e., if nanoparticles may persist as such after gastrointestinal digestion and be absorbed in the gut. The importance of studying the dissolution of nanoparticles under...
