E1103: Invertase
Main role: modifying sugar texture
Also listed as: beta-fructofuranosidase, sucrase enzyme preparation
What is E1103 (Invertase)?
Invertase is an enzyme preparation that breaks sucrose into glucose and fructose. It can help change the texture of sugar-based fillings without functioning as an artificial sweetener itself.
What does it do in food?
Its main role is modifying sugar texture. A carrier helps incorporate another ingredient, while a processing ingredient may support a manufacturing step or coating. The final declaration and exposure depend on the application and the labeling rules in the relevant market.
Food and formulation examples
- Soft-centered confectionery
- Fondant fillings
- Specified sugar processing
These examples describe formulation roles, not a list of unrestricted legal uses. Availability and permitted applications differ by country and food category.
Label names and ingredient questions
Look for E1103, E 1103, or the ingredient name. Related names and label terms include beta-fructofuranosidase, sucrase enzyme preparation. A family code can cover more than one specified form; check the full declaration when the distinction matters.
Breaking down sucrose changes the sugar mixture rather than making a filling sugar-free. Check total sugars on the finished product instead of treating an enzyme declaration as a low-sugar claim.
Is E1103 safe?
There is no meaningful personal risk estimate from an E number alone. Food-grade specifications, allowed uses, amount consumed, and individual circumstances all matter. The authorization record below gives the legal scope; it is not a claim that every possible use is appropriate.
A label identifies the ingredient but usually not its concentration. Calculating daily intake requires the amount in the food and the quantities eaten.
Authorization and conditions of use
The Great Britain food additive register lists E1103 as Invertase. This is an entry subject to its stated conditions, not unrestricted permission for every food. The record links to the applicable authorization terms. For an EU product, use the European Commission food additive database to check the relevant food category and limits. Other countries may use different names or rules.
