Effect of combination of three texture‐improving ingredients on textural properties of emulsified sausage‐containing salted egg white

摘要

Response surface methodology based on Box–Behnken was used to assess the effects of three kinds of texture‐improving ingredients, namely, mixed starch (MS) (6%–8%) of sweet potato starch and glutinous rice flour, k‐carrageenan (CG) (0.4%–0.6%), and konjac flour (KF) (0.8%–1.2%), on the firmness, elasticity, and water holding capacity (WHC) of emulsified sausage (ES) made from pork and salted egg white (SEW). The three kinds of texture‐improving ingredients individually presented different effects on firmness, elasticity, and WHC. Their synergistic effects were significant. The three response models obtained by ANOVA were suitable to predict firmness, elasticity, and WHC. These models can also be used to design formulations for different types of sausage with different firmness and elasticity. The combination of MS (7.36%), CG (0.60%), and KF (1.20%) can produce SEW‐containing ES with remarkable firmness (224.04 g), elasticity (8.62), and WHC (8.41).
