摘要： In this study, pectin was considered a soft matter, and the emulsification of low methyl-esterified citrus pectin (LMCP) was analyzed in the presence of calcium cations (Ca2+). The formulation of LMCP aggregates was called micelles, and they could be regarded as granular emulsifiers. The size and morphology of LMCP micelles were affected by the concentration of Ca2+, and this changed the emulsifying properties of LMCP. The particle size distribution range in LMCP solutions was first decreased and then increased with increasing Ca2+ concentrations from 0.00 to 10.00 mM. The concentration of Ca2+ affected the creaming index (CI) of emulsions and the size distribution of the emulsion droplets significantly. Tiny particles and cavities being detected on the oil droplet surface in cryo-scanning electron microscopy (SEM) micrographs illustrated that the stable emulsion could be considered a Pickering emulsion when different concentrations of Ca2+ were brought into the LMCP solution for the preparation of the emulsion.
