摘要： This study investigated the complexes formed between ovalbumin (OVA) and gum arabic (GA) and their ability to stabilize oil-water emulsions. The stability of the emulsions stabilized by the OVA/GA complexes was evaluated by measuring storage time (1-7 days), salt concentration (0-100 mM NaCl), and heat (40-90 degrees C, 30 min) stability at pH 3.8-7.0. The results showed that the stability of the OVA-stabilized emulsion was greatly improved by an OVA/GA ratio of 1:2 and acidic pH. Above or below 1:2, the emulsion was unstable due to depletion or bridging flocculation. Emulsions saturated with OVA/GA complexes were stable with changing pH, storage time, and heat treatment (up to 90 degrees C). However, the OVA/GA complexes did not improve the stability of the emulsions when salt concentrations were varied. The experimental results demonstrated that OVA/GA complexes could be used to prepare stable emulsion structures, which may be useful in the beverage industry. (C) 2015 Elsevier Ltd.
