Survey of the Viscozyme’s hydrolysis conditions on brown seaweed Sargassum mcclurei for fucoidan assisted-extraction

Abstract

In this study, the hydrolysis conditions of Viscozyme on brown seaweed Sargassum mcclurei collected in the Khanh Hoa sea were investigated to obtain fucoidan with a high yield. The survey conditions include the concentration of Viscozyme, the extract solution:raw seaweed ratio, and extraction time. The results showed that in the condition of 1% (v/w) enzyme concentration, the ratio of enzyme/raw seaweed was 25/1 (v/w), extraction time was 24 hours, and the obtained fucoidan
content reached 4.27%. The fucoidan analysed results showed that the obtained fucoidan belongs to the galactofucan group.
