Abstract Corn starch, potato starch and phosphate ester starch were evaluated for the effects of their respective and combined additions on the concentration, free sulfhydryl group content and relative hydrophobicity of chicken breast muscle salt-soluble proteins. On the basis of a 5-level quadratic general rotary unitization design, response surface methodology was employed to optimize the amounts of the three added starches. The respective addition had complicated effects on properties of chicken breast muscle salt-soluble proteins. The optimal combined addition was corn starch 1.6%, potato starch 1.6%, and phosphate ester starch 1.8%. Under the optimized conditions, the predicted concentration, free sulfhydryl group content and relative hydrophobicity of chicken breast muscle salt-soluble proteins were 24.3 mg/mL, 0.004 μmol/mg and 22.86, respectively.
