Abstract:

The extraction and isolation of natural antioxidants with potential in reducing the incidences of oxidative stress in the body and their potential inclusion into functional foods is a major topic of research at present. In this study, the aim was to investigate food-friendly Accelerated Solvent Extraction® (ASE®) samples and a Viscozyme® hydrolysate of the brown macroalga Fucus spiralis Linnaeus for total phenolic content and antioxidant activities. Furthermore, the effect of ultra-filtration steps on the total phenolic content and antioxidant activities of the Fucus spiralis hydrolysate were also evaluated.ethanolic-aqueous and methanolic-aqueous ASE® extracts displayed high phenolic contents of 37.03±3.01 and 39.04±5.72 µg phloroglucinol equivalents mg/sample, respectively. Both the Fucus spiralis Viscozyme® hydrolysate and ASE® extracts displayed in vitro antioxidant activities. Our findings suggest that food-friendly extracts of Fucus spiralis show potential as alternative sources of antioxidants.
