Competitive adsorption between sugar beet pectin (SBP) and hydroxypropyl methylcellulose (HPMC) at the oil/water interface

► Competitive adsorption between two polysaccharide emulsifiers is investigated for the first time. ► The mechanism of emulsification for both emulsifiers is further clarified. ► HPMC dominates the emulsion properties when present at >0.2 wt.%. ► The main role of SBP is to reduce the number of large droplets.
