Taking gum Arabic and gelatin as wall material, orange essence as core materials, the globular multi-core orange microcapsules was prepared by adopting compound condensation. Several probolems were studied, including wall material ratio , the core wall ratio, pH, types of curing agent, adding quantity on production rate , efficiency of microcapsules microcapsule, and the influence of microcapsule loading capacity. By the response surface test, the results showed that the ratio of gelatin and Arabic gum was 1.11.0 (mm), core wall ratio was 2.21（mm）, pH 3.6, curing agent content was 0.16%, the microcapsules of highest loads effectively was 73.16%.
