Is ester gum vegan?
It’s derived from wood rosin (from pine trees) reacted with glycerol; while the rosin is plant-based, glycerol can be plant-, animal-, or synthetic-derived, so vegan status depends on the supplier—check manufacturer or certification.

Mainly to emulsify and weight citrus oils in soft drinks so they stay uniformly mixed; it’s also used in chewing gum and some desserts as a stabilizer.
