Abstract

AZRINA CHAIDIR. Study on Seaweed as Alternative Dietary Fiber for Health Drink. Under the direction of USMAN AHMAD and SANTOSO Seaweed is one of marine commodities with high potential as dietary fiber source. The composition, dietary fiber and some physico-chemical properties of two red seaweeds powder (made from Eucheuma cottonii and Glacilaria sp) and one brown seaweed powder (made from Sargassum sp) was investigated using different blanching method and drying temperature. The methods of blanching are fresh water about 9 hours, rice powder solution with 5 % konsentration about 9 hours and combination fresh water and 0,5 % CaO solution. The oven temperature that used for drying seaweeds was 50 and 70 oC. The best blanching method for Eucheuma cottonii and Sargassum sp are fresh water about 9 hours, and for Glacilaria sp is combination fresh water and 0,5 % CaO solution. The best temperature for drying seaweeds are 70 oC. The seaweed powders have good appearance, smell and texture. Eucheuma cottonii powder has 72,19 % soluble dietary fiber, 11,23% insoluble dietary fiber out of 83,42% total dietary fiber. Glacilaria sp has 62,95% soluble dietary fiber, 20,67% insoluble dietary fiber out of 83,62% total dietary fiber. Meanwhile, Sargassum sp has 24,99% soluble dietary fiber, 57,62% insoluble dietay fiber out of 82,61% total dietary fiber. The health drink with Eucheuma cottonii and a combination of E. cottonii and Glacilaria sp powders as fiber source were accepted by panelis although less favourable in flavor and taste compared with commercial health drink.
