Panagiotis got his degree in Oenology - Food Technology in 2002 from Athens Technological University of Applied Sciences and later continued his studies at the University of Florence where he obtained a master in Methods of Synthesis in Organic Chemistry in 2004 and a PhD in Polyphenols Chemistry and Food Quality in 2008. During that period, his research activity was divided in laboratories of Analytical Chemistry, Organic Synthesis, Electrochemistry, Microbiology and wineries.In 2010 he joined the Food Quality group of Fondazione Edmund Mach where his activity focused in Food and Wine Metabolomics. In particular, his object is to establish methodologies for investigating fruit and wine metabolomes, by developing analytical protocols mainly with LC-MS techniques, data treatment and biomarker identification and hypotheses validation. He teaches at the Universities of Trento (Italy), West Attika (Greece) and Nova Gorica (Slovenia).

New publication in Foods entitled: Exploring Olfactory–Oral Cross-Modal Interactions through Sensory and Chemical Characteristics of Italian Red Wines. This work was made by the D:Wines consortium and funded by the by the MIUR project N. 20157RN44Y. 77 Italian red whole wines from 10 varieties, and corresponding deodorized wines, were evaluated by sensory descriptive assessment. In the absence of volatiles, correlation coefficients between sensory and chemical parameters mostly increased. linkOctober 2020
New publication in Journal of Argicultural and Food Chemistry entitled: Liquid Chromatography–Mass Spectrometry-Based Metabolomics for Understanding the Compositional Changes Induced by Oxidative or Anoxic Storage of Red Wines. This work was made in collaboration with the University of Zaragoza. We focused on the metabolomic changes in red wine caused by the redox storage conditions. Is the first paper that analyse the influence of reductive storage in red wine with an untargeted LC-MS protocol. The major metabolomic differences between oxidative and anoxic conditions were linked to reactions of acetaldehyde (favored in oxidative) and SO2 (favored in anoxia). linkSeptember 2020
New publication in Microorganisms entitled: Modulating Wine Aromatic Amino Acid Catabolites by Using Torulaspora delbrueckii in Sequentially Inoculated Fermentations or Saccharomyces cerevisiae Alone. In this work, we focused on the intra- and extracellular metabolomic changes of three aromatic amino acids (tryptophan, tyrosine, and phenylalanine) during alcoholic fermentation. The results indicate that pure S. cerevisiae fermentations produced higher amounts of N-acetyl derivatives of tryptophan and tyrosine and the off-odour molecule 2-aminoacetophenone. The sequentially inoculated fermentations showed a slower evolution and a higher production of metabolites linked to auxin and sulfonated tryptophol.linkJuly 2020
New publication in Scientific Reports entitled: Kinetic investigations of sulfite addition to flavanols. The paper deals with the reactivity of monomeric and dimeric flavanols in the presence of SO2, and the mechanisms of tannins sulfonation. The results proved that: (a) the major sulfonation route that leads quickly and in good yields to monomeric 4β-sulfonated derivatives passes through the acid-catalysed depolymerisation of proanthocyanidins; (b) monomeric flavanols lead to the same 4β-sulfonated products, although in a considerably slower manner, and also to other sulfonated regioisomers; (c) direct sulfonation of epicatechin is slightly faster than that of catechin. linkJune 2020

Released of a public repository data set on MetaboLights (MTBLS784). The data set includes the raw data and meta data of a LC-MS based metabolomics study of the metabolic changes caused by the methyl jasmonate (MeJa) pre-harvest application on two Vitis labrusca L. cultivars grape (Isabel Precoce and Concord), both grown in two Brazilian regions. Grape metabolome was extracted and analyzed with a MS based metabolomics protocol by UPLC-HRMS-QTOF and the unsupervised data analysis reveal clear separation between the two regions and the two cultivars, while supervised data analysis revealed biomarkers between MeJa and control group. Between the biomarkers, stilbenes, hydrocinnamates, flavonols and anthocyanins were identified. These results suggest that MeJa can be used as elicitor to secondary metabolism in grapes grown even under subtropical climate, affecting phenolic biosynthesis.linkApril 2020
New publication on Journal of Agricultural and Food Chemistry. The publication was focused on the use of LC-MS based metabolomics analysis to study the metabolome of Italian monomariatal red wines (Sangiovese from Tuscany, Sangiovese from Romagna, Teroldego from Trentino, Raboso and Corvina from Veneto, Nebbiolo from Piemont, Primitivo from Puglia, Montepulciano from Abruzzo, Sagrantino from Umbria, Aglianico from Campania, Cannonau from Sardegna, and Nerelo Mascalese from Sicily).

New publication on Food Packaging and Shelf Life. White wines were bottled in green and flint glass bottles and stored under typical supermarket shelf conditions. Light-strike fault, colour changes, light and temperature exposure were monitored up to 50 days. In general, green glass bottles secured wine quality for the tested period. Only a few flint glass bottled wines developed a fault due to light-strike after 1–2 days of supermarket shelf life, but all developed the fault after 20–40 days; so we considered the possibility of two mechanisms causing the problem. Flint-glass bottled wines stored on the bottom shelf developed the defect only slightly later compared with the wines on the top shelf. Moreover, storing the wines in dark and cold after a period of exposure to light did not eliminate the fault, indicating that the defect is probably additive. Monitoring the amount of light to which wines are exposed could prevent the fault.linkJanuary 2020
New publication on Metabolomics journal. The work focused on the effect methyl jasmonate application on Vitis labrusca L. grapes. Methyl jasmonate proved to be a potent elicitor also under tropical and sub-tropical climate conditions, having a great effect on polyphenols profile. If we take in consideration the climate changes in Europe, it could an important tool for the viticulturist in the future. The work was part of Lais Moro PhD project, and made in collaboration between Fondazione Mach (Italy) and University of São Paulo (Brazil). linkJanuary 2020
