Effects of the incorporation ultrasound with varied intensities (0-800 W) into thermal-induced gelation process on gelling properties myofibrillar protein (MP) were explored. In comparison single heating, ultrasound-assisted heating (<600 led to significant increases in gel strength (up 17.9%) and water holding capacity 32.7%). Moreover, moderate treatment was conducive fabrication compact homogenous networks small pores, which could effectively impair fluidity allow redundant be entrapped within network. Electrophoresis revealed that facilitated more proteins get involved development With intensified power, α-helix gels lowered pronouncedly a simultaneous increment β-sheet, β-turn, random coil. Furthermore, hydrophobic interactions disulfide bonds reinforced by treatment, support construction preeminent MP gels.
