Abstract

The main aims of this study are determining seasonal chemical composition of green seaweed and evaluating usage of a food source with different processing techniques. For this purpose, Ulva rigida were collected from Çanakkale Strait, Türkiye and amino acid, fatty acid and proximate composition were determined seasonally in both fresh and dried samples. According to results; Ulva rigida contains high protein and amino acids content whereas it has low fat content differs in the range of 0.46-0.85 % in fresh samples and 1.81-4.53 % in dried ones. In the following, the obtained algae samples in the all seasons were processed into salad and algae soup. Most favorite consuming options determined as algae salad among groups.
