Study on microencapsulation of anthocyanins
The composition of wall materials and the technology of spray-drying for the microencapsulated anthocyanins were studied. The optimum microencapsulation technologies of anthocyanins were that the ratio of anthocyanins and wall materials was 20%, the ratio of maltodextrin and β-cyclodextrin was 3∶1, the concent of gum acacia was 10%, inlet air temperature was 120℃ and outlet air temperature was 80℃.
