High pressure-cooking of chicken meat batters with starch, egg white, and iota carrageenan

摘要

High pressure/cooking combinations (200 MPa and 400 MPa, 70°C) of chicken gels caused the formation of less compact and aggregated microstructures, which had better binding properties and were less hard. Pressurizing caused a general decrease In color parameters. The addition of starch, egg white or iota carrageenan increased water binding of meat batters. The effect of adding starch and iota carrageenan on textural properties was similar, both causing an Increase in hardness and chewiness. High pressure Influenced the action of the Ingredients and the extent of the effect was related to the type of ingredient and the pressure level but pressure clearly predominated over Ingredient effects.
