About
Invert syrup is a liquid sweetener produced by the acid or enzymatic hydrolysis of sucrose into approximately equal proportions of glucose (dextrose) and fructose. It is widely used in confectionery, baked goods, beverages, and preserves to prevent sugar crystallisation, retain moisture, and deliver a sweetness level roughly 25% greater than sucrose.
Safety summary
Invert syrup is classified as a food ingredient rather than a food additive and carries no formal Acceptable Daily Intake (ADI); its safety profile mirrors that of its constituent free sugars, glucose and fructose. Excessive intake of free sugars—including those from invert syrup—is linked to obesity, dental caries, dyslipidaemia, insulin resistance, and non-alcoholic fatty liver disease, with the free-fructose fraction of particular metabolic concern. The WHO recommends limiting total free sugar intake to less than 10% of total energy intake, with conditional guidance to reduce this to below 5% for additional health benefit.
Regulatory landscape
| Jurisdiction | Status | Note |
|---|---|---|
| FSANZ (Food Standards Australia New Zealand) (Australia) | Approved | Invert sugar is permitted as a food ingredient (not a scheduled additive) under the Australia New Zealand Food Standards Code; no E number or specific use-level restriction applies.source |
| EFSA (European Food Safety Authority) (European Union) | Approved | Invert sugar syrup is defined and regulated as a sugar product (not a food additive) under Council Directive 2001/111/EC, which sets compositional requirements (≥50% invert sugar on dry matter basis). It carries no E number and is outside the scope of food-additive Regulation (EC) No 1333/2008.source |
| FSSAI (Food Safety and Standards Authority of India) (India) | Approved | Invert sugar is explicitly permitted as an ingredient in fruit juices, confectionery, and other processed foods under the Food Safety and Standards (Food Products Standards and Food Additives) Regulations, 2011. FSSAI Contaminants Regulations cap lead at 5.0 mg/kg for all types of sugar syrup and invert sugar where sulphated ash exceeds 1.0%.source |
| FDA (Food and Drug Administration) (United States) | Approved | Invert sugar is affirmed as GRAS under 21 CFR 184.1859 for direct use as a general-purpose sweetener and humectant in food at levels consistent with Good Manufacturing Practice (GMP); no maximum daily intake has been established. |
