Response surface methodology(RSM) was used to optimize the preparation conditions of medium-chain triglycerides(MCT) microcapsules.Base on single factor tests,a series of Box-Benhnken design experiments were used to obtain a mathematical regression model for encapsulation efficiency as response of three variables.The results indicated that the optimum preparation conditions were as follows: mass ratio of core material to wall material 3.56:6.44,emulsifier dosage 3.59%,and the solid mass fraction of emulsion... |
