Influence of cations, pH and dispersed phases on pectin emulsification properties.

ABSTRACT: The cooperativity of six cations (Ca²⁺, Mg²⁺, Zn²⁺, Al³⁺, Cr³⁺ and Fe³⁺), three pectins (sugar beet, high and low methyl esterified), three dispersed phases (medium chain triglycerides (MCT), orange oil and hexadecane), time (30 days) and pH (2.0 and 6.0) has been investigated in the formation and stability against coarsening of oil-in-water emulsions. Cations generally influenced emulsion stability in the following order (most stable) Ca²⁺ ​> ​Mg²⁺ ​> ​Al³⁺ ​> ​Cr³⁺ ​> ​Zn²⁺ ​> ​Fe³⁺ (least stable). This order largely coincided with that of the strength of pectin-cation interactions showing that the higher the affinity of cation for pectin the less stable the
