Abstract:

β-cyclodextrin was taken as wall materia1 and the deer placenta polypeptide was made into microcapsules by ultrasonic. The orthogonal test results showed that the optimum conditions of process are as follows: ratio of core material to wall material 1:20, ultrasonic power 160 W, ultrasonic time 100 min, ultrasonic temperature 30 ℃. Under these conditions, the embedding rate reaches 60.63%.

Key words: deer placenta polypeptide, ultrasonic, microcapsule
