Abstract


Instant drink of ethanolic extract Sargassum polycystum with ginger flavor was made from seaweds which was processed into powder and have undergone processes of drying, extraction, cocrystalization, and sieving into powder. The objective of this research was to produce a formula of the seaweed instant drink which has a high antioxidant activity and is preferred by consumers. The formula that was used in this research waere ethanolic extract of S. polycystum, sugar and ginger. The compostion of formula including control (0:3:1), formula 1 (0.1:2.9:1), formula 2 (0.2:2.8:1), formula 3 (0.3:2.7:1), formula 4 (0.4:2.6:1), formula 5 (0.5: 2.5:1), and formula 6 (0.6:2.4:1). The result showed that the instant drink contained the value of antioxidant activity by 25.70-65.41%, total fenol of 27.74-100.36 mg GAE/gram, water levels of 0.44-1.99%, ash levels of 0.06-11.54% and the value of hedonic color 2,4-3,2(don’t like – like); hedonic flavor 1.29-3.66 (very don’t like – like); and hedonic taste 1.32-3.59 (very don’t like – like).
