E1103 / Other additives
Invertase
Safety in brief
Safe
Recorded EatMatrix rating, not a new clinical review. The amount, your sensitivities and country rules still matter.
- Watch for
- No allergen or sensitivity is recorded for this ingredient here. Check the whole product label; this is not an allergen-free guarantee.
- Our advice
- Read the whole food label and consider how often you eat the product. A name or E number does not tell you the amount, and an ingredient rating cannot assess the entire food.
What it is
Invertase is a naturally occurring enzyme that breaks sucrose down into glucose and fructose (invert sugar). It is used in candy-making, particularly to create soft-centered chocolates, and in the production of artificial honey and certain syrups. As an enzyme used in small amounts during processing, it is broken down like other proteins and is considered safe.
Also appears on labels as: Invertase, Sucrase, β-fructofuranosidase, Saccharase, EC 3.2.1.26, E1103, E 1103, E-1103, Enzyme Invertase, Food enzyme Invertase, Yeast invertase, Sugar-splitting enzyme.

Research & body effects
Health notes from our ingredient record
- Generally recognized as safe at typical food-processing levels.
- As a protein-based enzyme, it carries a theoretical risk of allergic sensitization in rare cases, mainly relevant to occupational exposure rather than consumers.

These links come from the original ingredient record. They are separate from the source reviews above and have not all been checked for the exact ingredient, amount consumed or claim. Dates are shown newest first.
- Invertase: Enzymatic Safety and Applications in Food Processing — EFSA Panel on Food Contact Materials, Enzymes and Processing Aids, EFSA Journal - Enzyme Safety Assessment (2023). A detailed safety evaluation of invertase (E1103) examining its use as a processing aid enzyme in food production. The research confirmed that invertase, naturally occurring in yeast and plants, presents no safety concerns when used according to good manufacturing practices. The study noted its specific activity in converting sucrose to glucose and fructose, improving product texture and sweetness profile. The assessment highlighted its natural origin and excellent safety record, supporting its continued use in food processing applications.[safe]
Country rules
Country checks for E1103
Permission depends on the market, type of food, amount and conditions. A scientific opinion or an E-number alone does not establish a legal use. These checks are separate from the stored EatMatrix rating.
Compare all eight markets and their sources
| Market | What is checked |
|---|---|
| European Union | Regulation (EC) 1333/2008, Annex II Part B, version , contains the exact code E1103: Invertase. Listing alone does not allow every food use. Part E food categories, limits, specifications and applicable later acts still need a product-specific check. Source read: . |
| Great Britain | The FSA register record for E1103 (Invertase) lists “Authorised” in England, Scotland and Wales. Register updated: 01 April 2025; record checked: . Food-specific conditions and specifications still need a separate legal check. |
| United States | Complete current-use review pending. Any scoped provision in the label guide above applies only to the stated use. FDA explains the applicable food-additive and GRAS framework. |
| Northern Ireland | Review pending. Check the applicable EU rules and territory arrangements; the GB register alone does not establish this status. FSA guidance is a starting source, not a verified permission for this entry. |
| Canada | Named food-use records located. Health Canada lists the preparations below for specified foods and purposes. This is conditional permission for those uses, not approval of every product or a personal safety verdict. The enzyme name alone does not identify the permitted source organism or production strain. Each source and food-use condition below must also match. Source tables captured . List publication dates are shown separately. Good Manufacturing Practice (GMP) is a condition of use, not an unlimited amount or a recommended intake. Food and Drug Regulations B.16.003 requires the listed source, purpose, amount and other conditions to match. The official consolidation read was current to 21 September 2026; product specifications and applicable later changes still need checking.

EatMatrix reading: match the exact preparation and food first. A manufacturing limit is not an acceptable daily intake (ADI). A label without the amount cannot establish exposure, and an unlisted name here does not establish a ban. |
