Özet

Proximate analysis, fatty acid profile and mineral content were investigated in brown (Cystoseira corniculata, Padina pavonia) and red seaweeds (Laurencia papillosa and Jania rubens). The highest protein content was obtained for P. pavonia (35.40% dry weight) followed by L. papillosa (34.65% dry wt). Lipid contents of seaweeds ranged from 6.73% for L. papillosa to 0.12% dry weight for J. rubens. The fatty acid compositions of seaweed species included 31.66-47.97% saturated fatty acids (SFA), 23.04-32.06% monounsaturated fatty acids (MUFAs) and 11.58-18.08% polyunsaturated fatty acids (PUFAs). Mineral analysis showed that the seaweeds contain high amounts of both macro minerals (Ca, Mg, Na, P and K) and trace elements (Zn and Mn).
