Study on preparation of sIg microencapsulation

The formulation and process of microencapsulation of Ig of corn were studied by using micro- porus starch and malt dextrin as wall material and Ig as support materials.Based on the test results the optimal conditions were as follows:malt dextrin:micro-porus starch was 1:1,Ig content was 10%, solid content was 40%,spray drying inlet air temperature 140℃,outlet air 80℃.
