Three varieties of Kappaphycus alvarezii, which were widely cultivated in Semporna, Sabah include Aring-Aring, Crocodile Skin, and Green Flower was dried through freezed drying process and then analyzed to determine its proximate chemical composition, vitamin C, mineral element, and also fatty acid profile. The seaweeds found were high in dietary fiber (81.80 – 84.60%) and ash (6.36 – 8.97%) and low in lipid content (0.40 – 0.54%) on dry weight (DW) basis. Protein content in these seaweeds are range from 4.67 – 4.73% DW. Vitamin C content in these seaweeds is significantly high (21.10 – 32.57 mg/100g). The PUFA content in Aring-Aring was 8.02%, Crocodile Skin 8.45% and Green Flower 12.12%. This study was conducted to give a basic nutritional data for these three varieties of Kappaphycus alvarezii as guidance for further investigation especially for heat sensitive components such as antioxidant.
