Abstract

The present work investigated effects of high-pressure homogenization (HPH) pressure (0, 40, 80 and 120 MPa) on physicochemical, functional and rheological properties of clam myofibrillar protein (CMP). Results showed that HPH changed the CMP secondary and tertiary structures. Absolute zeta potential and protein solubility increased but particle size and turbidity of CMP decreased after HPH treatment. Both of emulsifying properties and foaming properties were significantly improved. The shear stress, apparent viscosity and the viscosity coefficients reduced, but flow index increased. Application of HPH improved the physicochemical, functional and rheological properties of CMP, and 120 MPa was the optimal pressure for modification.

Keywords: Functional properties; High-pressure homogenization; Myofibrillar protein.
