Orthogonal Test Design for Optimization of Emulsifying Effectiveness of Phytosterol Adding to Milk Using Tween as Emulsifiers

Article Preview

Abstract:

Effect of four emulsifiers including Tween 20, Tween 40, Tween 60 and Tween 80 on emulsifying effectiveness of phytosterol adding to milk was studied by single factor and orthogonal experiment. The concentrations of four emulsifiers were all 0.2%, 0.3%, 0.4%, 0.5%, 0.6% and 0.7%. The optimal emulsified conditions showed as follows: the optimal concentrations of Tween 20, Tween 40, Tween 60 and Tween 80 were 0.40%, 0.40%, 0.20% and 0.30%, respectively, the emulsification R reached 1.043 under the conditions mentioned above.
