Is Invertase a major allergen?

Invertase is not derived from any of the 14 major allergens that UK law requires to be emphasised on food labels.

Is Invertase safe?

Invertase is authorised as a food additive in the UK and the EU, listed on the Register of Food Additive Authorisations.

Why it's used

Invertase is used as an enzyme preparation to control the texture and sweetness of confectionery and chocolate products. It prevents sugar crystallisation and creates a softer, smoother texture by converting sucrose into a mixture of glucose and fructose, which are more soluble and less prone to crystallisation.

Health notes

Invertase is authorised as a food additive in the UK and the EU, listed on the Register of Food Additive Authorisations. It functions as a processing aid, specifically an enzyme preparation, and is not typically considered to have a significant health impact at the levels used in food. EFSA has evaluated enzymes used as processing aids, and invertase is permitted for use under specified conditions.
