E492: Sorbitan tristearate

What is E492?

E492 is sorbitan tristearate, an emulsifier formed by combining sorbitan (a dehydrated form of sorbitol) with stearic acid, a saturated fatty acid. It is a waxy, cream-coloured solid that mixes well with fats.

Origin and production

It is produced by esterifying sorbitol with stearic acid at high temperature. The sorbitol comes from glucose, while the stearic acid can be derived from vegetable oils or from animal fats.

Why is it used?

In chocolate and confectionery coatings, sorbitan tristearate helps control fat crystallisation and reduces 'fat bloom', the dull white film that can form on chocolate. It is used in chocolate candies, cocoa-coated wafers, biscuits, cakes and other confectionery.

Vegan, vegetarian and halal

Because the stearic acid may be plant- or animal-derived, E492 is not automatically vegan or vegetarian; only the manufacturer can confirm the source. Those following halal or kosher diets may look for certification for the same reason.

Safety and regulation

Sorbitan tristearate is authorised as a food additive in the European Union. In its re-evaluation of sorbitan esters, EFSA identified a risk that some population groups could exceed the acceptable daily intake at high levels of consumption.
