Mecanisme fizico-chimice a proceselor redox cu transfer de electroni implicate în sistemele vitale, tehnologice şi de mediu | Journal: | Intelligent Valorisation of Agro-Food Industrial Wastes 2021 | Conference: | Intelligent Valorisation of Agro-Food Industrial Wastes | Abstract: | The work investigated the processes that take place during the forced thermal oxidation of sunflower oil. The results obtained in the study showed a major impact of thermo-oxidation (90 ± 2 °C). The supplied air with a speed of 8 ÷ 10 L h-1 for 50 hours) influences physico-chemical indicators of the studied oil. Acidity index of fresh sunflower oil increased 13.7-fold, with a value of 2.46 mg KOH/g-1 fat for thermo-oxidized oil compared to the initial value of 0.188 mg KOH g- 1 fat. Thermo-oxidation of sunflower oil caused a significant decrease in the saponification index, which indicates a significant increase in degree of polymerization and leads to an increase in the viscosity of the studied sunflower oil. |
