Enzymatic extraction has also been reported to increase the extractability of bioactive compounds from several
brown algae (Heo, Park, Lee, & Jeon, 2005; Siriwardhana et al.,2008). These cell wall-degrading enzymes help to weaken or disrupt the cellwall structure, break down complex interior storage materials, thereby facilitating the release of the intracellular bioactive compounds from algal biomass. Furthermore, the hydrolytic breakdown of high-molecular-weight (HMW) polysaccharides and proteins may contribute to enhanced antioxidant activities (Siriwardhana et al., 2008).
