Study on the Microencapsulated Natural Vitamin E
This paper studied the spray drying microencapsulation technology of natural vitamin E. The result showed that the wall materials and their optimum composition was Arabic gum 22.5％，dextrin 25％and corn syrup 52.5％. The suitable proportion of core material and wall material was 6∶5. And the suitable homogenizing pressure was 30MPa. The optimum spray drying conditions for microencapsulation of natural vitamin E were the feed temperature was 60℃,feed flow rate was 150mL/min,temperature of entering wind was 195℃,and temperature of out wind was 70℃.
