Nowadays, more and more products of doubtable origin are entering the market, downgrading the value of authentic products and the labor of honest producers. Consequently, it becomes a necessity the traceability and the authenticity of these products, first, to protect the local production and, second, to inform the consumers about the origin of the products. The most capable and promising analytical technique for identifying the geographical traceability of individual products is the analysis of stable isotopes. For example, analyzing the δ 18 ? and δ 2 H of the milk and the water of the...

Isotopic analysis is suggested from the E.U. as the most suitable and most reliable method for detecting the authenticity and the traceability of food products such as honey. The isotopic ratio of carbon 13 in honey reflects the photosynthetic cycle of the original plant. The δ 13 C of honey has range from -25‰ to -27‰, consequently any other value beyond those limits suggests an addendum of something else than honey. For example, in honey, often, there are additives of sugars like fructose or sugars from plants like corn or sugar cane. These sugars have a δ 13 C that ranges from -9,5‰ to...

Wine products such as vinegar are susceptible to serious fraud incidents, as the result of a mixing of chemical ingredients and water, with a direct impact on both consumers and producers. However, a manufactured with a natural vinegar displays different isotopic identity despite their chemical identity. The isotopic distribution of elements of raw materials is determined by local conditions (e.g. rainfall, soil, topography, climate) during the environmental and biochemical pathway from the atmosphere, rain water and soil, plant (vineyard), wine and finally the vinegar. 18 ?/ 16 ?, 13 C/ 12...

This exploratory research effort describes a metabolomic approach to elucidate the link between the circulatory and excreted metabolome during the 2 nd trimester of pregnancy. NMR metabolomics was employed, in order to assess the maternal serum and urine fingerprint. The metabolites were integrated into a metabolic correlation network, to visualize the resulting correlation matrices in circulatory and excreted metabolomes. It would be of outmost importance to capitalize on metabolomics, in order to unravel the biochemical pathways towards further understanding of pregnancy metabolism.

In previous GWAS work in obese/overweight 77 Korean women, five new loci associated with BMR and BMI, including NRG3, OR8U8, BCL2L2-PABPN1, PABPN1, and SLC22A17 were identified. This study aimed to identify key metabolites and metabolic pathways controlled by significant genes (mGWAS). Methods: Through the ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS), the data were analyzed using partial least-squares discriminate analysis (PLS-DA) score plots. Possible metabolic pathways related to lean and obesity were detected by metabolites...

A stable isotope dilution LC-MS/MS method was developed for the Alternaria toxins alternariol (AOH), alternariol monomethylether (AME) and tenuazonic acid (TeA) in herbs. Tentoxin (TEN) was quantified using matrix calibration. Solid phase extraction was applied for sample purification. Limits of detection (LOD) and quantification (LOQ), recoveries and intra- and interday precisions were determined for a comprehensive validation. The method was used to evaluate the mycotoxin contamination in various herbs and infusions.

Given that culture condition of crops affects metabolites of products and consequently consumers’ metabolism, we investigate the metabolic difference of conventional and naturally grown green coarse tea (Bancha). Previous work in 2015 showed that only naturally grown Bancha tea was observed to significantly increase the consumers’ locomotive energy expenditure with counter decrease of household activities, resulting in a higher shift of exercise level. In terms of metabolite categories that distinguished between the culture conditions, conventional tea was observed to express higher primary...

The official control of balsamic vinegars (BV) is limited to basic physicochemical properties such as total acidity and total reducing sugar content. High performance liquid chromatography (HPLC) is the recommended method for the determination of sugars, organic acids and 5- hydroxy-methyl-2-furfuraldehyde, a potential quality criterion. Nuclear magnetic resonance spectroscopy (NMR) is a powerful tool for monitoring food quality due to its high reproducibility and sensitivity. In the present study, the potential of NMR in BV analysis was investigated for future applications in the official...

METROFOOD-RI is a European Research Infrastructure (RI) aiming at promoting metrology in food and nutrition. In the present work, a mapping of existing RIs and networks of the South Eastern European (SEE) METROFOOD partner countries (i.e. FYROM, Greece, Hungary, Republic of Moldova, Romania, Slovenia), related directly or indirectly to the Agrifood sector, is presented and discussed. As reference METROFOOD partner country, The Netherlands is considered.

METROFOOD-RI - “Infrastructure for Promoting Metrology in Food and Nutrition” is composed by a Physical (P-RI) and an electronic infrastructure (e-RI). PRO-METROFOOD project (H2020 INFRADEV-02-2016, GA n. 739568), which represents the “Early Phase” of METROFOOD-RI, foresees a specific task aimed to develop a pilot service with the related pilot access to demonstrate the actual capability and added-value of METROFOOD-RI to supply services and to test its inter-operability acting as organised Physical-RI. In particular, the pilot service consists in the development of new...
