The project develops up-to date topic in the subject area, offers high-quality research of natural products (NPs) and flavours (FLs) and tends to impact the biodiversity, traceability and authentication issues of targeted samples (major EU concerns), as well as to unlock the potential (useful activities of the samples/NPs). Targeted samples are unexplored or insufficiently investigated honeys, honeydews, bee-products, wines, cheese, others. While characteristic NPs (secondary metabolites) already possess flavours, other flavour compounds can derive from precursors during processing, fermentation, dry-curing, heating, others (e.g. Maillard reactions, Strecker degradations, retro-aldol reactions, Amadori rearrangements, heterocyclizations, lipid oxidations and others). NPs/FLs isolation involves application of selective preparative procedures followed by the organic analysis applying modern chromatographic and spectroscopic techniques. Specific project goal is to determine reliable chemical fingerprints of targeted samples depending on biodiversity of natural sources in different regions. Varieties of acetate, shikimate, mevalonate and/or deoxyxylulose biosynthetic pathway derivatives are expected to be found. Among them, it can be possible to find specific or nonspecific chemical biomarkers characterizing certain sources. In addition, the obtained NPs or selected samples will be evaluated in order to unlock their potential, particularly antioxidant activity by different assays and corrosion inhibition potential with in-situ and ex-situ electrochemical/non-electrochemical techniques.
