Abstract:
Recenijy. the global demand for proteins is increasing with pc-puiation growth. Although
Seaweeds are often promoted for their poJysaccharides. they demonstrate higher protein
contents even more diansome tenesirial plants. Tlierefore. applicatioG of protein extracts will
be a vahie addition. Tins studywas earned out to determine seaweed protems and the protem
profile o f selected seaweed species of Sri Lanka. Initially, crude protem contents of seaweeds
harvested from the same geographical Location were evaluated. Naairiily grown Turbinari
ncmaia (Pkaeophyti?, Graciiaria salicornia CRhodopliYta), Cauhrpa ientihfera (ChJorpJiyta)
and a cultivated variety Kappaphycia aherezii (Rliodophyta) were col Leered from Jaffiia in
December 2019 and ilieix crude protein confects were determined. For the analysis. freshJy
harvested seaweeds were washed oven dried (if 60 PC), powdered and sieved to obtain similar
partible size and were preserved in airtd it containers at room temperature. After drying, yield
was reduce d nearly 10 tnnes of tlie fresh samples. The crude protem content (“-'o') and moisture
content {%) of die above seaweeds o& dry weight b asis were S-. 1.5 56 ± 0.0 05 9.9.6193 ± 0.0119.
14.511 = 0.009,10.528 ± 0.0653 (protem content) and 5.52 = 0.01, 9.09 ± 0.05. 8 74 ± 0.03^
9.33 ± 0.04 {moisture content), respectively. The results revealed that the crude1 protem content
of seaweed species varied as. Caulerpa ienrilifera- Kappaphycvs alverzzii:-- Gracilnria
salicomia.- Turbmarin ornaia. In addition, the de-ermiiiation of the soluble protein: and the
protem profiles of the above seaweeds ire in progress
