it can be inferred that deacetylated KGM may react with actin by hydrogen bonding, thereby improving the hydrophobic interactions of the protein and forming a denser and more uniform network structure. These results showed that KGM with a higher DD as a novel additive significantly improved the qualities of Alaska surimi subjected to high temperature treatment. Therefore, KGM may be used as an alternative gel enhancer and quality improver in surimi products because of its noncaloric nature and low dosage effect, as well as its beneficial effects on the gel properties.
