Seaweeds contain potentially good nutrients along with sources of protein, carbohydrates, fibers, minerals and vitamins, and have low lipid content. Among them, E. cottonii is a potential and interesting new It is known to be a source of natural materials. In this study, the characteristics, physical properties and functional evaluation of E. cottonii were compared and studied. Moisture content was highest in G.E and high in non roasted samples. Crude protein content was the highest in C.S.E and high in non roasted samples. The content of ash was highest in R.G.E and it was generally higher in the samples grown. The crude fat content was the highest in R.C.S.E and it was measured higher in the cultured and treated samples. The total carbohydrate content of R.G.E and R.C.S.E was higher than that of roasted carbohydrate. The yield of carrageenan was the highest in R.C.S.E and it was high in cultured and treated samples. The physical properties of Carrageenan were generally higher in G.E. Leucine was the essential amino acid and glutamic acid and aspartic acid were the most essential amino acids. The content of K was the highest in the mineral contents, Fe and P were significantly lower than the other values, and the content of Se was not found. The electron donating ability was the highest value of water extracted samples. Among them, C.S.E and R.C.S.E were the highest. ABTs radical scavenging activity was the highest value of 80% ethanol extracted and R.C.S.E was the highest. SOD‐liked activit was highest in 80% ethanol and R.C.S.E was the highest. Reducing power activity showed no significant difference between the samples. Total phenolic acid content also showed no significant difference among the samples. Total flavonoid content was highest in water samples and G.E was the highest. Support or Funding Information As a result of this study, the samples treated with the culture solution were measured at higher values. The yield of Carrageenan was close to 20% in R.C.S.E and as a result, carrageenan contained in E. cottonii was found to be able to obtain optimal yields in the future through the use of gelling agents, thickeners, stabilizers, surfactants, And the like. In addition, E. Cottonii is expected to be used as a natural antioxidant. This abstract is from the Experimental Biology 2019 Meeting.
