Abstract

In current study, proximate compositions (ash, lipid and protein) and fatty acid profiles of 5 different brown macroalgae (Stypopodium schimperi, Halopteris scoparia, Cystoseira compressa, Padina pavonica, Sargassum vulgare) collected from Iskenderun Bay (Arsuz and Kale regions) in July 2019 were determined, The highest and lowest ash values were found in Halopteris scoparia (28 +/- 0.1%) and Cystoseira compressa (21 +/- 0,1%), respectively. The lowest and highest lipid amounts of brown algae tested in the study were found in Cystoseira cornpressa (2.00%) and Stypopodium schimperi (6.36%). respectively. While the highest protein content was determined in Halopteris scoparia (9.79 +/- 0.02%) and Cystoseira compressa (9.50 +/- 0.3%), the lowest protein content was obtained from Padilla pavonica (4.20 +/- 0.16%). The saturated(SFA) and monounsaturated (MUFA) fatty acid compositions of brown algae were 75.11-92.45 % and 4.44-23.1%, respectively. In conclusion. biochemical compositions and especially, the high levels of palmitic acid indicated that brown macroalgae can be considered as a potential resource in terms of obtaining biologically new products in the nutraceutical industry and food industry.
