20.500.12556/RUL-134135 Liposomal encapsulation of oleuropein and an olive leaf extract molecular interactions, antioxidant effects and applications in model food systems The influence of actively/passively encapsulated oleuropein on DPPC liposomes thermal and structural properties, and its antioxidant capacity against lipid peroxidation were investigated. Also, an oleuropein-rich olive leaf extract was encapsulated in soy phosphatidylcholine (PL-90 g) and incorporated in model and commercial drinks. Oleuropein induced a concentration-dependent broadening and splitting of the gel-to-liquid phase transition temperature. Fluorescence measurements revealed a fluidizing effect on liposomes below their gel-to-liquid phase transition temperature, and a higher lipid ordering above, especially to active encapsulation. Oleuropein also showed an antioxidant effect against lipid peroxidation in PL-90 g liposomes. PL-90 g Liposomes with olive leaf extract showed a mean diameter of 405 ± 4 nm and oleuropein encapsulation efficiency of 34% and delayed oleuropein degradation at pH 2.0 and 2.8 model drinks. In conclusion, greater effects were observed on the structure and fluidity of DPPC liposomes when oleuropein was actively encapsulated, while its incorporation into acidic foods in encapsulated form could enhance its stability. encapsulation liposomes oleuropein olive leaf extract phospholipid membranes peroxidation liposomi enkapsulacija oljka Olea europaea rastlinski ekstrakti listi oljke oleuropein fosfolipidne membrane true false true Angleški jezik Slovenski jezik Članek v reviji 2021-12-24 11:40:03 2021-12-24 11:40:03 2022-09-13 03:53:28 0000-00-00 00:00:00 2021 0 0 Str. 84-97 Vol. 16 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 577.3:634.63:615.014.6 1557-1858 10.1007/s11483-020-09650-y 33992195 RAZ_Gonzalez_Ortega_Rodrigo_2021.pdf RAZ_Gonzalez_Ortega_Rodrigo_2021.pdf 1 7CE5B5D0CDA37D94214FBDC5A77947F0 b8bfebef6bb527c44e1f31e04597b7500b4170f28befb9f16e4dcbab4966a48e fa1dc0d3-64a9-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=152459 https://link.springer.com/article/10.1007%2Fs11483-020-09650-y 0 edbda7eb-64a9-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=152458 Biotehniška fakulteta 0 0 0
