Effects of konjac glucomannan on heat-induced changes of physicochemical and structural properties of surimi gels

This work demonstrated the protective effects of konjac glucomannan (KGM) on the physicochemical and structural properties of surimi gels subjected to 120 °C. The T2 relaxation of LF-NMR which was used to detect water mobility, changed more obviously with the addition of deacetylated KGM than with the native, which indirectly implied that deacetylated KGM more pronouncedly influenced the protein structure. Hydrophobic interaction, ionic,...
