The knowledge of the biogenic amines present in wine is important to consumers in terms of their potential threats of toxicity to human and to wine producers as a result of market impact. In the scientific field, biogenic amines have the potential to be applied as indicators of food spoilage. Biogenic amines are essential at low concentrations for metabolic and physiological functions in animals, plants, and microorganisms, but at high concentrations can induce adverse reactions in susceptible individuals. Despite the intensive research aimed at determining and reduction of biogenic amines, our current knowledge remains far from complete. However, a number of factors that influence the biogenic amines concentration in red wine have been already described. Most of them are related to the winemaking conditions in the cellars and some of them are environmental factors. During winemaking it is important to consider all factors beginning from viticulture practices, alcoholic and malolactic fermentation and physiochemical composition of wine, as well as, aging and storage of wine. This paper reviews changes of the concentration of biogenic amines depending on technological processing of grape and wine.Key words: biogenic amines, red wine, winemaking conditions, fermentation, microbiological decarboxylation
IZVLEČEK BIOGENI AMINI V RDEČEM VINU: VPLIV TEHNOLOŠKE PREDELAVE GROZDJA IN VINAPoznavanje prisotnih biogenih aminov v vinu je pomembno za potrošnike in pridelovalce zaradi potencialne nevarnosti toksičnosti za človeka in posledično tržnih vplivih. Na znanstvenem področju imajo biogeni amini potencial, ki se uporablja kot pokazatelji kvarjenja hrane. Biogeni amini so v majhnih koncentracijah bistvenega pomena za normalne metabolne in fiziološke funkcije pri živalih, rastlinah in mikroorganizmih, lahko pa imajo škodljive učinke pri velikih koncentracijah ter predstavljajo tveganje za zdravje občutljivih posameznikov. Kljub intenzivnim raziskavam, usmerjenim v določanje in zmanjšanje vsebnosti biogenih aminov, naše sedanje znanje še zdaleč ni dokončno. Opisanih je več dejavnikov, ki vplivajo na vsebnost biogenih aminov v rdečih vinih. Večina od njih je povezanih z vinarskimi razmerami v kleti, od katerih so nekateri tudi okoljski dejavniki. V vinarstvu je pomembno upoštevati vse dejavnike, ki se začnejo z vinogradniških vplivi, alkoholno in jabolčno-mlečnokislinsko fermentacijo, fizikalno-kemijsko sestavo vina, kakor tudi staranjem in skladiščenjem vina. V tem članku so pregledno podane spremembe vsebnosti biogenih aminov glede na tehnološke postopke predelave grozdja in pridelave vina.
