| High internal phase emulsions(HIPEs) were prepared using defatted sesame meal(DSM) and peeled defatted sesame meal(PDSM) as stabilizers, and the basic properties of the emulsion were studied. The effects of sesame meal dosage, oil phase volume fraction, pH and ion concentration on the microstructure, particle size and rheological properties of HIPEs were examined. The results indicated that at an oil phase volume fraction of 0.75, the minimum dosages of PDSM and DSM were 5.0% and 30%，respectively; at DSM and PDSM dosage of 5.0%, the highest oil phase volume fractions of PDSM and DSM stabilizing HIPEs were 0.75 and 0.85, respectively; DSM and PDSM stabilized HIPEs had the best stability under the condition of neutral pH as well as proper amount of NaCl. The rheological properties showed that there was an elasticity-dominated gel-like network structure inside HIPEs. As the increases of DSM and PDSM dosages, the particle size of HIPEs decreased and distributed uniformly, and the viscoelasticity increased. |
