Abstract：The esterification of soybean soluble polysaccharide (SSPS) and octenyl succinic anhydride (OSA) was used to prepare a novel green polymerized soybean polysaccharide (OSA-SSPS).OSA-SSPS stabilized oil-in-water (O/W) emulsions are good embedding and transporting carriers for lipophilic bioactive compounds.The electrostatic complexation of acid soluble soy protein (ASSP) and OSA was used to prepare an ASSP/OSA-SSPS emulsion in this study.The advantages OSA-SSPS were analyzed specifically by measuring its emulsifying properties,the droplet size distribution of the ASSP/OSA-SSPS emulsion,the ξ-potential,and the microstructure,and comparing them with those of SSPS.The droplet size of the ASSP/OSA-SSPS emulsion was less affected by pH and ionic strength,and ASSP/OSA-SSPS was more stable than SSPS.Therefore,OSA-SSPS had a better emulsifying stability than SSPS.The emulsifying activity and emulsifying stability of OSA-SSPS and the storage stability of the ASSP/OSA-SSPS emulsion were systematically analyzed in this study,which provides a theoretical guide for the preparation of OSA-SSPS and its industrial production in O/W emulsion.
