o:6299 NEW APPROACHES IN EXTRACTION AND PRESERVATION OF ULVA LACTUCA SEAWEED POLYPHENOLICS AND NATURAL PIGMENTS en New ways of utilizing the unexploited marine product, seaweed from the Adriatic Sea (Ulva lactuca L.) were established. Due to the benefits of this macroalga, the focus was to apply green and safe technologies for the extraction and preservation of seaweed’s valuable bioactive compounds. Optimization extraction protocol for the main bioactive compounds and their preservation through innovative microencapsulation techniques (spray and freeze-drying) methods were established. The Ulva extract possessed a high content of total polyphenols, chlorophyll A and B, and carotenoids. The obtained microencapsulates improved Ulva’s stability, limiting the inactivation of the sensitive polyphenolic compounds, achieving high encapsulation efficiency, and high antioxidant activities. This valuable sea resource may be used as an uncostly bio-product rich in functional compounds, with commercial utilization and development of Ulva-based blue-biotech industries. 1552099 10.60738/03ak-mn82 2024-12-03T13:50:51.048Z 44 no 46 Nada Ćujić Nikolić Institute for Medicinal Plant Research, ''Dr. Josif Pančić'', Belgrade 0000-0002-6736-3637 46 Dragana Drakulović Institute of Marine Biology, University of Montenegro, Kotor, Montenegro 46 Jelena Vulić Faculty of Technology, University of Novi Sad 46 Zorana Mutavski Institute for Medicinal Plant Research, ''Dr. Josif Pančić'' Belgrade 0000-0003-2514-2542 46 Milica Radan Institute for Medicinal Plant Research, ''Dr. Josif Pančić'' Belgrade 0000-0002-6727-7624 46 Nemanja Krgović Institute for Medicinal Plant Research, ''Dr. Josif Pančić'' Belgrade 0000-0003-3611-9911 46 Ivana Čabarkapa Institute of Food Technology, University of Novi Sad application/pdf 788659 https://unilib.phaidrabg.rs/o:6299 no yes 1 70 92000004 71A10 Abstracts Book 79 79 17th World Congress on Polyphenols Aplications 2024
