Marine macroalgal (seaweed) polysaccharides are highly promising for next-generation applications in several industries. However, despite the reported comprehensive potential of these polysaccharides, commercial products are scarce on the market. Seaweed cultivations are increasing in number and production quantity, owing to an elevated global trend of utilization interest in seaweed. The extraction of polysaccharides from seaweed generally generates low yields, but novel methods are being developed to facilitate and improve the extraction processes. Current areas of applications for seaweed polysaccharides mainly take advantage of the physicochemical properties of certain polysaccharides, such as gelling, thickening and emulsifying. However, many of the numerous bioactivities reported are still only at research level and lack clinical evidence for commercialization. It has been suggested the construction of smaller units may generate better defined molecules that are more suitable for biomedical applications. Enzymatic modification is a promising tool for the generation of more defined, targeted biomolecules. This review covers; structural differences between the most predominant marine algal polysaccharides, extraction processes, modification alternatives, as well as a summary of current and potential next-generation application areas.

15For the first time, the uptake of chlorophyll pigments from the main edible seaweeds (Nori, 16 Sea Lettuce and Wakame) has been investigated. During the micellarisation process, 17 dephytylated chlorophylls were favoured over phytylated chlorophylls (a and c series were 18 2 favoured over b series and oxidised chlorophylls were preferentially micellarised). This is the 19 first time chlorophyll b derivatives have been found to be resistant to the in vitro digestion of the 20 food matrix, indicating they are also potentially absorbable by enterocytes during the ingestion of 21 green vegetables and fruits. Nori chlorophylls stand out as the most bioaccessible, followed by 22 those in Sea Lettuce and Kombu. During the Caco-2 cell absorption process, dephytylated 23 chlorophyll derivatives were also favoured over phytylated ones, with pheophorbide c being the 24 most absorbable chlorophyll pigment. It is also the first time that chlorophyll oxidation reactions 25 have been observed during cell absorption. The uptake of chlorophyll derivatives from edible 26 seaweeds resulted in Caco-2 cell lines with a chlorophyll profile dominated by dephytylated and 27 oxidised derivatives.28
