碩士 / 國立臺灣海洋大學 / 食品科學系 / 106 / In this study, we investigated the general testing specifications and indicative ingredient concentrations of different fucoidan products in Taiwan market. Eleven kinds of commercially available fucoidan products were collected to measure the content of uronic acid, sulfate and total sugar, then compared with in vitro antioxidative capacities (DPPH and ABTS free Radical scavenging ability), and further analyze the cconcentrations of the fucose, index component of fucoidan by high performance liquid chromatography.
The concentrations of uronic acid were between 0.15 ± 0.00~19.44 ± 0.20 g/100 g, the concentrations of sulfate were 0.21 ± 0.01~20.73 ± 0.46 g/100 g. Among them, the highest value was sample A which used Okinawa brown algae as raw material. The total sugar concentrations were between 0.06 ± 0.01~681.91 ± 16.61 mg/g, and the sample J showed the lowest level. In vitro antioxidative capacity tests, sample E was the best one for DPPH and ABTS free radical scavenging abilities. The fucose content was the highest 40.21 ± 0.33 g/100 g in sample A.
This study established the relevant test specifications for different fucoidan products and the regulatory compliance of the commercially available fucoidan products.
