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. 2024 eng info:eu-repo/semantics/conferenceProceedings
