Modification of reduced-sodium carp myofibrillar protein by a combined strategy with ultrasound and MgCl2 treatment: physicochemical, structural and functional properties
This study finds that combined ultrasound and magnesium chloride treatment enhances myofibrillar protein properties, suggesting benefits for the aquatic product industry.
Key Points
Combined treatment significantly improved solubility and emulsification activity of reduced-sodium carp myofibrillar protein.
The zeta potential increased to 11.39 mV after treatment, indicating better stability of the protein.
FT-IR analysis showed a change in the protein's secondary structure, with increased β-sheet content and reduced α-helix.
The treatment's effectiveness highlights its potential application in processing reduced-sodium aquatic products.
