The effects of high-voltage electrostatic field (HVEF) on the physicochemical and functional properties of myofibrillar protein (MP) extracted from channel catfish were investigated. All samples were treated by HVEF with different voltage (0, 10, 20, 30, and 40kV) for 20min. The results showed that HVEF treatment reduced the surface hydrophobicity, Ca2+-ATPase activity, total sulfhydryl content, and emulsifying properties of the samples compared with the control (sample without HVEF treatment). However, the solubility, particle size, the absolu...
