| Sumario: | Silver carp (Hypophthalmichthys molitrix) is now available in sufficient quantities for surimi production. To improve thesurimi gels, addition of microbial transglutaminase (TGase) was evaluated. This work deals with the optimisation of setting usingmicrobial TGase in silver carp. Concentration of microbial TGase, temperature and time were optimised to improve the mechanicalproperties of surimi from silver carp. Empirical models providing a quantitative interpretation of the relationship between the operationalconditions of the setting during the surimi production were developed. Shear stress was strongly affected by the variables studiedwhile shear strain was moderately affected. Optimal predicted properties were obtained by employing the following setting conditions:a concentration of microbial TGase of 8.8 g/kg of surimi, at 39.6°C for 1 hr. Under these conditions, a surimi from silver carp withshear stress of 146 kPa and shear strain of 1.59 was obtained. |
