Abstract
Abstract Based on electrostatic layer-by-layer deposition, the influence of soybean soluble polysaccharides (SSPS) and beet pectin (BP) on the physicochemical properties of lactoferrin-coated orange oil emulsion was investigated. The physicochemical stability of orange oil emulsions was characterized by droplet size and distribution, zeta-potential, turbidity, rheological behavior, transmission profiles using LUMiSizer and degradation of volatile compounds in the emulsions during the storage. Results showed that the droplet characteristics of secondary emulsions were greatly dependent on the polysaccharides concentration and type. The zeta-potential values were decreased from 39.5 mV to −23.2 mV and −37.6 mV, respectively, for the SSPS and BP concentrations from 0 to 0.75 wt%, which indicated that anionic polysaccharides were adsorbed to the droplet surfaces. SSPS and BP concentration of 0.35 wt% was sufficient to saturate the LF-coated droplets and preferred effectively to increase the physical stability of the emulsion systems. During the storage of 4 weeks at 55 °C, SSPS and BP could significantly ( p
