In this study, the influence of ester gum levels on the formation and stability of model orange oil-in-water emulsions stabilized by modified starch were examined.
In particular, the aim was to show that the ester gum stabilizes orange oil emulsions by inhibiting Ostwald ripening, which to the author’s knowledge has not been
reported before. Also the influence of ionic strength and heating
on the stability of the emulsions to identify factors that may
impact their long-term stability in beverage applications were examined.
The results of this study will be particularly useful for
the optimization of flavour emulsions used in the food, beverage,
and fragrance industries.
