Abstract

To explore the effect of ultrasound and ultrahigh pressure on the functional properties of myofibrillar protein (MP) and added value of bonito fish, the improvement of the functional properties of myofibrillar protein were studied by the experiment with different ultrasonic time and ultrahigh pressure treatment. The results showed that the solubility and emulsification of MP increased with the extension of ultrasonic time. After treatment with different ultrahigh pressure intensity, the solubility of MP reaches maximum at 200-300 MPa, and emulsification was the best at 200 MPa. During temperature scanning, the elastic module was decreased with ultrasonic time and the intensity of the pressure. The ultrasonic and ultrahigh pressure treatment can affect the weight of protein molecular.
