摘　　要：采用正交实验研究了超临界CO2萃取花椒油的工艺,探讨了萃取压力、温度和时间等因素对花椒萃取率的影响。并初步研究了在一定条件下,利用同轴喷嘴将萃取出的花椒油直接喷雾干燥制备微胶囊过程中,壁材浓度、壁材流量、CO2流量、进风温度等对包埋率的影响。In this paper, such factors affecting the supercritical CO2 extraction of zanthoxylum oil as extraction pressure, temperature, and time were studied with orthogonal experimental design. In microcapsulation with spray drying by using coaxial nozzle, the factors affecting the degree of encapsulation, such as wall material concentration, wall material flow rate, CO2 flow rate, inlet-air temperature were also investigated.
