Asigurarea calitaţii vinurilor prin gestionarea riscurilor chimice

Abstract

In teza sunt prezentate rezultatele cercetarii continutului reziduurilor de pesticide, a ionilor de cupru si plumb in strugurii recoltati de pe pantatiile de vita-de-vie din doua regiuni viti-vinicole din tara si corespunderea indicilor de calitate a lor cu standardele in vigoare. Vinurile obtinute din vinificarea acestor struguri se caracterizeaza prin indici inalti de calitate, alcoolitate si extractivitate majorate, si aciditate volatila redusa ; ele au un continut redus de reziduuri de pesticide , dioxid de sulf si fier, cationi de contaminare, radionuclizi si micotoxine. In rezultat au fost formulate masuri tehnologice pentru reducerea riscurilor chimice si asigurarea calitatii vinurilor.

The thesis presents the results of research content pesticide residues of copper and lead in the grapes harvested on plantations of grape vines in the wine-growing two regions in the country and their compliance with quality indicators standards. Wines produced from grapes vinification these indices are characterized by their high quality, alcohol and extractivitate increased, and low volatile acidity; they are low pesticide residues, sulfur dioxide and iron cations contamination, radionuclides and mycotoxins. The results were formulated chemical technological measures to reduce risks and ensure the quality of wines.
