Studies on Microencapsulation Processing of Cinnaldehyde

Cinnaldehyde was microencapsulated with the method of spray drying using the gum arabic and maltodextrin as the principal wall materials.The effects of processing conditions, such as composition of wall material,dosage of emulsifier,wall material concentraion,the ratio of cinnaldehyde to wall material,inlet air temperature,inlet speed of mixture and air pressure of ejector were discussed.The optimum processing conditions were determined by orthogenesis test.The results of antimicrobial experiments showed that the products had the function of controlled release antisepsis.
