| Abstract: |
| In order to improve the stability of giant salamander oil, giant salamander oil microcapsule was prepared by spray drying method. After selection of wall materials, with embedding rate as index, the effects of ratio of wall materials, mass ratio of wall material to core material, dosage of wall material and dosage of emulsifier on the microencapsulation of giant salamander oil were studied. Based on single factor experiment, the optimal process conditions were determined by Box-Behnken design as follows: ratio of wall materials 3.44∶1, mass ratio of wall material to core material 5.37∶1, dosage of wall material 6.46% and dosage of emulsifier 2%(based on the mass of wall material). Under these conditions, the embedding rate of giant salamander oil microcapsule was 88.06%. |
