dc.description.abstract Introduction. The beneficial effects on health result from the protective action of astaxan-thin, (AXT) a powerful antioxidant capable of scavenging free radicals and protecting cells from oxidative stress. The study aimed to evaluate the protective role of astaxanthin derived from Haematococcus pluvialis in reducing the thermal oxidation of fatty acids in vegetable oils. Material and methods. Astaxanthin, obtained by extraction from the biomass of Haemato-coccus pluvialis, at a concentration of 0.26-0.29 mg/mL, was added to olive, sunflower, al-mond, walnut, sesame, and poppy seed oils. The progression of oxidation was monitored based on the formation of conjugated dienes. The formation of conjugated dienes was monitored spectrophotometrically. Results. Astaxanthin reduced the content of conjugated dienes in sesame, almond, and walnut oils by 30-34%. A strong antioxidant effect of AXT was noted in the case of poppy seed oil, for which the formation of conjugated dienes was decreased by 42% and the oxidation was delayed by 60 min when exposed to high temperatures compared to native oil. For sunflower oil, which exhibited a high degree of thermal oxidation, addition of AXT reduced the formation of conjugated dienes by 22% during the experiment. Conclusions. Astaxanthin from Haematococcus pluvialis significantly reduced the formation of conjugated dienes, indicating that it does not act as a prooxidant in various vegetable oils. en_US
dc.description.abstract Introducere. Beneficiile astaxantinei (AXT) pentru sănătate rezultă din acțiunea sa protectoare. Acest antioxidant puternic neutralizează radicalii liberi și protejează celulele împotriva stresului oxidativ. Studiul a avut ca scop evaluarea rolului protector al astaxantinei, obținute din Haematococcus pluvialis, în reducerea efectelor oxidării termice asupra acizilor grași din uleiurile vegetale. Material și metode. Astaxantina, obținută prin extragere din biomasa de Haematococcus pluvialis, a fost adăugată la uleiurile: de măsline, floarea-soarelui, migdale, nuci, susan și de mac în concentrația de 0,26-0,29 mg/ml. Evoluția procesului oxidativ a fost monitorizată în baza formării dienelor conjugate. Formarea dienelor conjugate a fost înregistrată spectrofotometric. Rezultate. Astaxantina a redus cu 30-34% conținutul dienelor conjugate în uleiurile de susan, migdale și de nuci. Astaxantina a demonstrat un efect antioxidant semnificativ pentru uleiul de mac, expus temperaturilor înalte, diminuând formarea dienelor conjugate cu 42% și amânând oxidarea cu 60 de minute, în comparație cu uleiul netratat. Pentru uleiul de floarea-soarelui, care a prezentat un grad ridicat de oxidare termică, adăugarea de AXT a redus formarea dienelor conjugate cu 22%. Concluzii. Astaxantina derivată din Haematococcus pluvialis a redus semnificativ formarea dienelor conjugate în diverse uleiuri vegetale, indicând lipsa efectului prooxidant. en_US
