Special Issue Information

Dear Colleagues,

The food market is currently a global market, with food being exchanged all around the world. The retailing food business is becoming more competitive. Alongside it, e-commerce is becoming more widely used by consumers. The result of these worldwide food exchanges are the growing consumers’ concerns with food authenticity, especially when the food products are added-value products associated to a particular denomination, such as the ones defined by a European Regulation, e.g., Protected Denomination of Origin (PDO), or Indication of Geographical Provenance (IGP). Although several regulations have been imposed to control such products, the number of fraudulent practices is increasing, with high repercussions for the good name of such food products. The development of technological approaches to control such products has been arising, allowing to control the two dimensions concerned in a robust authenticity system: geographical provenance and species/varietal/breed composition.

Hence, in this Special Issue, we invite authors to submit cutting-edge research papers or reviews on the application of technological approaches (OMICs; chemical; etc.) suitable to characterize one or both dimensions of a food/beverage authenticity scheme. This Special Issue also aims to give a defined perspective as to where we stand in terms of technological approach to set the basis to implement an authenticity scheme for a given food/beverage product. As part of the current European Smart Specialization strategy in the Agrifood sector, the strengthening of analytical integrated tests in food and beverages may be considered as part of the “Key Enabling Technologies” (KETs), enhancing capacity to deliver innovative, sustainable, and inclusive growth in the agrifood sector.

The interest in developing reliable wine authenticity schemes is a hot-topic, especially for wines with recognized added-value. In order to accomplish this goal, two dimensions need to be considered: the grapevine variety determination and the geographical provenance. The aim of this study was to develop a multidisciplinary approach applicable to wines from the sub region Melgaço and Monção of the demarcated Vinho Verde region and from the demarcated Douro region. The proposed scheme consists on the use of DNA-based assays to detect Single Nucleotide Polymorphisms (SNPs) on three genes of the anthocyanin pathway (UFGT, F3H and LDOX) coupled with High-resolution melting (HRM) analysis aiming the varietal identification. The Alvarinho wines revealed to have the same haplotype using this marker set, demonstrating its applicability for genetic identification. In addition, to assess their geographical provenance, a multi-elemental approach using Sr and Pb isotopic ratios of wine, soil and bedrock samples was used. The isotopic data suggest a relation between Sr and Pb uptake by vine roots and soil’s texture and clay content, rather than with the whole rock’s isotopic ratios, but also highlights the potential of a discriminating method based on the combination of selected isotopic signatures.

A lateral flow immunoassay for sensitive detection of skeletal troponin I (TnI) as a specific, thermostable marker of muscle tissue was developed. Due to the antibodies’ choice, the assay specifically detects mammalian TnI (in beef, pork, lamb, and horse) but does not detect bird TnI (in chicken or turkey), thus enabling differentiation of these types of raw meat materials. The assay is based on a sandwich format of the analysis using gold nanoparticles as labels. The time of the assay is 15 min, and the TnI detection limit is 25 ng/mL. A buffer solution is proposed for efficient extraction of TnI from muscle tissues and from finished meat products that have undergone technological processing (smoking–cooking–smoking, cooking and smoking). The possibility of detecting beef addition in minced chicken down to 1% was demonstrated. Full article

Amino acids play a relevant role in wine quality and can allow for classifying wines according to the variety. In this work, the amino acid contents of Albariño, Godello, and Treixadura wines, three autochthonous varieties from Galicia (NW Spain), were determined. During three consecutive vintages, these varieties were grown on the same vineyard and were harvested at optimum maturity, and the wines were elaborated following the same enological protocol. The identification and quantification of the primary amino acids were carried out by high-performance liquid chromatography with photodiode array detection, after a derivatization. Amino acid contents in these white varieties were within the range of values reported for other European wines, but Treixadura wines showed the highest concentrations, while wines from the Albariño variety showed the lowest contents. Apart from proline, whose concentrations were caused by yeast release, the most abundant amino acids were aspartic acid, glutamic acid, lysine, arginine, asparagine, alanine, and histidine. Principal component analysis separated wines by variety according to their amino acid contents. Full article
