Proximate composition and amino acid content of red seaweeds, Kappaphycus alvarezii, from
Langkawi and Sabah in Malaysia were determined in order to evaluate their potential nutritional
value. The crude fibre content of seaweed from Sabah (at 8.95%) was found to be significantly
higher than that of Langkawi (at 7.86%) (P0.05). Total
17 amino acids were found in both seaweeds, aspartic acid, gulamic acid, leucine are the major
constituent and followed by. This study showed that Kappaphycus alvarezii from both habitats
contained different amount of some of the essential amino acid and proximate composition it
can be used as ingredients to improving nutritive value in human diets.
