Abstract
The present study focused on proximate composition, moisture, ash, lipid, protein, carbohydrate, dietary fiber and physicochemical properties to determine the water holding capacity, oil holding capacity, and water swelling capacity of H. valentiae red seaweed. The antioxidant properties of methanol extract were performed by superoxide and nitric oxide radical scavenging activity. The superoxide scavenging radical (50-250 μg/mL) was an inhibition of 89.06 ± 0.44μg/mL which is significantly higher than the standard ascorbic acid 75.67 ± 0.20μg/mL. Nitric oxide assay observed that (15-100 μg/mL) exhibited the maximum nitric oxide scavenging was 87.22 ± 0.80μg/mL which is significantly higher than the standard ascorbic acid 74.35 ± 0.67μg/mL. The results were establishing the potential of the seaweed was exploited the nutritional value and pharmaceutical applications.
