Abstract
Depolymerization of fucoidan induced by contact glow discharge electrolysis(CGDE) was investigated. To utilize fucoidan as a functional food material after CGDE, organic acids were used as a electrolyte in CGDE process. Experimental results showed that CGDE using organic acid reduced the molecular weight of fucoidan effectively. As electrolyte concentration increased, onset voltage of glow discharge decreased and onset current of glow discharge increased. From the variation of molecular weight of fucoidan with the reaction time, it was demonstrated that the degradation of fucoidan followed a first-order rate law. Molecular weight of fucoidan treated with CGDE using organic acid was about 77 times lower compared to initial fucoidan with little free sulfate.
