The mineral content of some species Caulerpa, Ulva,
Sargassum, Eucheuma, Gracilaria, Gelidiella and
Kappaphycus was investigated. These are the major variety of seaweeds
available in Sabah South China Sea (Malaysia) and contained high proportions
of ash content (20.56- 40.5%). The green and brown seaweeds ash content
(37.27-40.5%) was higher than the red seaweeds (20.56-22.41%). The iron
content was rich in the sequence of Gelidiella>Caulerpa> Sargassum>
Eucheuma and its range was found to be 6.6-10.94 mg/100 g dry weight.
The major seasonal deviation was found to be 9.25% Mg, 6.44% Ca and 5.3%
Fe. This study was conducted to create a nutritional data for consumption
and utilization in the industry.
