Abstract

Yield and composition of green biomass and its leaf protein concentrate (LPC) were determined for Eleocharis dulcis (Burm. f.) Hensch., an aquatic weed. The plants yielded 1350 g m −2 green biomass and 216 g m −2 LPC in two cuts within 100 days. The green biomass showed 14% protein content and 65.50% extractability of protein N in the LPC. The LPC contained 56.88% protein which was digestible in vitro to 67.87%. The amino acid composition of LPC was found to be nutritionally adequate, except for sulphur-containing amino acids. The results suggest the promising potential of this plant for LPC production.
