20.500.12556/RUL-135242 Stabilisation of lutein and lutein esters with polyoxyethylene sorbitan monooleate, medium-chain triglyceride oil and lecithin Lutein is a challenging compound to incorporate into food, as it is poorly soluble and unstable in aqueous solutions. In this study, the aim was to prepare stable encapsulates of lutein and lutein esters using feasible and straightforward techniques. Fine suspensions based on polyoxyethylene sorbitan monooleate and medium-chain triglyceride oil micelle-like units with 3.45% lutein esters or 1.9% lutein equivalents provided high encapsulation efficiencies of 79% and 83%, respectively. Lutein encapsulated in fine suspensions showed superior stability, as 86% was retained within the formulation over 250 days at 25 °C in the dark. Under the same storage conditions, only 38% of lutein remained in corresponding formulations. Higher encapsulation efficiencies were achieved with lecithin emulsions, at up to 99.3% for formulations with lutein, and up to 91.4% with lutein esters. In lecithin emulsions that were stored for 250 days, 17% and 80% of lutein and lutein esters, respectively, were retained within the formulations. lutein lutein esters encapsulation emulsions polyoxyethylene sorbitan monooleate lecithin aditivi barvila lutein luteinski estri emulzije kapsulacija true false true Angleški jezik Slovenski jezik Članek v reviji 2022-03-02 11:27:06 2022-03-02 11:27:07 2022-09-14 04:12:22 0000-00-00 00:00:00 2021 0 0 15 str. iss. 3, art. 500 Vol. 10 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 547.979.8:664.022.33 2304-8158 10.3390/foods10030500 53319427 RAZ_Gombac_Zala_2021.pdf RAZ_Gombac_Zala_2021.pdf 1 0BEF874B4BF81EBE34BF93F3356AD5AC 18addcdb7c26ad7ff7da0675cbea0025dd54d150be9f6de02a78a699a322b342 67c1e6b4-9a13-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154186 https://www.mdpi.com/2304-8158/10/3/500 1 0b489c08-9a13-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154185 Biotehniška fakulteta 0 0 0
