| Abstract: | In this study, conjugated linoleic acid was embedded by sodium oetenylsueeinate starch. Through the response surface methodology experiment, the optimum parameters of conjugated linoleic acid microeapsulation were as follows ： core material/wall material 1 ： 2.87, embedding time 1.56 h, and em- bedding temperature 42 ℃. Under this optimum condition, encapsulation percentage of conjugated linoleic acid microeapsulation was 93.22%. Microencapsulated powder particles after spray drying was plump, inseparable, orderliness, and smooth through the scanning electron microscopy. |
