Comparing E445 - Glycerol esters of wood rosin vs E1452 - Starch aluminium octenyl succinate

Overview

E445 - Glycerol esters of wood rosin

Glycerol esters of wood rosin (E445) are food additives made by joining glycerol to the resin acids found in pine wood rosin. In drinks, they act as a “weighting agent” that helps flavor oils stay mixed so the beverage looks and tastes uniform from first sip to last. They are also called ester gum on labels.

E1452 - Starch aluminium octenyl succinate

Starch aluminium octenyl succinate (E1452) is a modified starch used to help oil and water stay mixed, keep drinks uniform, and protect delicate flavors. It appears in small amounts, mainly in beverage emulsions and spray‑dried flavor powders, where it adds stability without changing taste.

Popular questions

  1. Is ester gum bad for you?

    No—at permitted food levels it’s considered safe; EFSA set an acceptable daily intake of 25 mg/kg body weight, and typical exposures from beverages are well below this.

  2. What is ester gum in drinks?

    It’s a weighting agent/emulsifier that keeps citrus flavor oils evenly dispersed in soft drinks, preventing separation and “ringing” at the surface; it’s often used as an alternative to brominated vegetable oil.

  3. 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.

  4. What is ester gum made of?

    Glycerol esters of wood rosin—produced by reacting refined wood rosin (rosin acids from pine) with glycerol and then purifying the product.

  5. What is ester gum used for?

    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.
