This study investigated the preparation of emulsions stabilised by two different classes of biopolymer; sugar beet pectin (SBP) – a plant derived protein-polysaccharide complex, and hydroxypropyl methylcellulose (HPMC) – a surface active polymer. Previous work has demonstrated that protein-stabilised interfaces can be displaced by bile salts. The focus of this work was to understand how hydrocolloid emulsifiers interact with bile salts, as these interactions are possibly more complex than those observed in protein-stabilised interfaces.
