“…The cell walls of algae are porous and soft. Fucoidan is easily soluble in acid solvents [13,14]. In the results of polysaccharide extraction from the brown algae Hyriopsis cumingii, it was found that the polysaccharide yield increased with increasing stirring speed.…”

“…The phenolic compounds present in seaweed vary from species to species, therefore, alginate extracted from different seaweed species could have a significantly different intrinsic viscosity although the same extraction procedure is followed. [22] Besides formaldehyde, alternative chemicals can be used at the soaking stage to facilitate the removal of pigmentation, fat, protein and the phenolic compounds from the seaweed, such as ethanol [20], acetone [25], sodium hypophosphite [26], chloroform [27] and petroleum ether [28]. Soaking using only water is also reported in several processes [29], which is mainly to rehydrate and swell the dried seaweed particles.…”

“…Then, the soluble sodium alginate is released from the seaweed biomass matrix, transporting it into the liquid phase (extraction solution). The extraction efficiency and the alginate property are mainly affected by extraction temperature, time, pH and alkaline concentration [27], which are discussed in detailed in the following sections.…”

“…Previous research had carried out the integrated extraction of fucoidan and alginate according to the conventional and hydrothermal biorefinery concept by using a smart pressure cooker. Two products have been produced, i.e., alginate and fucoidan (Sugiono & Ferdiansyah, 2019). However, this method is ineffective because the yield of fucoidan is relatively small and takes a long time.…”
