This paper attempted to construct a high internal phase emulsion (HIPE) through altering interfacial behaviors using the electrostatic interaction between positive chitosan and negative octenyl succinic anhydride (OSA) starch. The partial polysaccharide complex of OSA starch/chitosan was used stabilize HIPE, which able adsorb at oil droplet interface prevent coalescence droplets. wettability starch enhanced with addition positively charged chitosan, leading formation complexes. impact pH concentration on size, surface charge, behavior were investigated, further confirmed by atomic force microscopy. presence facilitated stable HIPE gel-like structure satisfactory centrifugal oxidative stability. These results are useful provide information for fabricating polysaccharide-based delivery systems, may help expand their application in food industry.
