Optimization of Zanthoxylum bungeanum Maxim.Oil Microcapsule Process
In this study,with arabic gum and starch sodium octenyl succinate as the composite wall materials,spray drying technology is used to prepare Zanthoxylum bungeanum Maxim.oil microcapsule.Response surface test method is used to establish a quadratic regression equation model with the embedding rate and the yield of Zanthoxylum bungeanum Maxim.essential oil as the response values,and the proportion of wall materials,the ratio of composite wall materials and the outlet air temperature of spray drying as the response factors.The best process parameters for preparing Zanthoxylum bungeanum Maxim.oil microcapsule are obtained:the proportion of wall materials is 40％,the ratio of composite wall materials(arabic gum∶starch sodium octenyl succinate)is 1∶1 and the outlet air temperature of spray drying is 90 ℃.The embedding rate of the obtained Zanthoxylum bungeanum Maxim.oil microcapsule is 93.54％,the yield of Zanthoxylum bungeanum Maxim.essential oil is 95.35％,and it is superior to other products of Zanthoxylum bungeanum Maxim.in terms of the stability and sensory evaluation.
