Assessment of Marine Microalgae's Bioactive Extracts Potential for Food Applications.

ABSTRACT: The growing demand for sustainable and functional food ingredients has driven interest in marine microalgae as a source of bioactive compounds. This study evaluates the bioactivity, safety, and metabolite profile of extracts from Dunaliella salina and Pavlova gyrans, produced through two extraction methods: osmotic shock and bead milling with ethanol. Aqueous extracts were rich in peptides and amino acids, while ethanolic extracts contained higher pigment concentrations, underlining distinct nutritional biochemistry profiles. Both extracts exhibited significant antioxidant activity (4 mg mL^{- 1}), with aqueous extracts demonstrating a stronger effect. Cellular antioxidant activity assays using the Caco-2 cell line confirmed comparable efficacy between extraction methods
