Study on Microencapsulation Conditions of Flavonoids from Corn Silk

Abstract

Abstract: The purpose of this experiment is to improve the corn silk flavonoids stability by microencapsulation technology.Microencapsulation of the flavonoids from corn silk with beta-cyclodextrin and the effect of the processing parameter of pestle method on the microencapsulation efficiency and yield were investigated.The results showed that the products with high quality could be obtained at the conditions such as the ratio of the wall materials to the core material 1:14,grind time 35 min,the concentration of beta-cyclodextrin 10%,and the temperature of grind 48 ℃.On these conditions,the microencapsulated efficiency of the product reached 85.6%.

Key words: corn silk, flavonoid, microencapsulation, beta-cyclodextrin
