Abstract

Indonesia has a potency to be the biggest producer of seaweed in the world1 but most of the seaweeds are under-utilized, and their health benefits are unknown. Seaweeds can be a very interesting natural source of new compounds with biological activity. 2 The significant changes in age-associated nutrient requirements among others is the need for energy decreases but the protein requirements increase with age. The significant micronutrients that may be associated with deficiencies in elderly women include calcium, iron, zinc, and other trace minerals and vitamins are available in seaweeds.3 This study was conducted to create a nutritional data for two species of seaweeds commonly found in Binuangen coast of south Banten in order to popularize its consumption and utilization in Indonesian older people. The proximate composition, minerals, protein, fat, carbohydrate profiles of two tropical edible seaweeds, Ulva fasciata and Rhodymenia palmata, were studied. The protein and carbohydrate content of seaweed were 11.55-17.61 g/100 g and 24.23- 25.90 g/100 g dry weight (d.w.) respectively. The seaweeds were low in lipid content on dry weight basis. These seaweeds contain 7.98-11.01% macro-minerals (Na, K, Ca and Mg) and 695.48- 2048.19 ppm trace elements (Fe, Zn, Cu, and Mn). These seaweeds are nutritionally valuable thus making them a potential health ingredient for use in older people nutrition. The average daily consumption of 5 g of Ulva fasciata and Rhodymenia palmata is sufficient to meet 5-40% and 10-115% respectively of the trace elements daily requirement for older people, respectively.
