Fucoidan is a sulfated polysaccharide which is mainly found in brown seaweed like Sargassum sp. In this study, fucoidan was extracted with two distinct methods, one was using 0.1 N HCl (Fucoidan A) and the other 0.1 N H3PO4 (Fucoidan B). Yields of HCl and H3PO4 extractions were 7.50 and 7.02%, respectively. Characterization of crude fucoidan was carried out through Fourier-transform infrared spectroscopy (FTIR), followed by total carbohydrate and total sulfate level measurement. Crude fucoidan was then used for the determination of its binding activity against Trichothecenes T-2 toxin. Quantitative analysis of 50 µg/mL T-2 toxin binding capacity shows the efficiency of 59.52% at pH 3.0 and 58.37% at pH 6.8 for crude fucoidan A. As for crude fucoidan B, efficiency of T-2 toxin binding capacity has value of 58.12% at pH 3.0 and 57.33% at pH 6.8. Meanwhile, Commercial crude fucoidan extract from Fucus vesiculosus sp. was used as control for T-2 toxin binding capacity analysis with efficiency of 57.31% at pH 3.0 and 56.64% at pH 6.8. Therefore, fucoidan from Sargassum sp. can be utilized better as mycotoxin especially T-2 toxin binder than from Fucus vesiculosus sp. through efficiency result of fucoidan binding capacity.
