GI=0. Zero calories. E968 approved. ADI not specified by EFSA. This page covers the science, the safety data, the baking chemistry and the B2B pricing for erythritol in bulk from EU stock. If you’re sourcing erythritol for food production, this is where you start.
Erythritol is a four-carbon sugar alcohol (polyol) with the molecular formula C&sub4;H&sub1;&sub0;O&sub4; and a molecular weight of 122.12 g/mol. It is naturally present in trace amounts in fermented foods (beer, wine, cheese), certain mushrooms and some fruits. Commercial erythritol, however, is produced via fermentative biotransformation of glucose using osmophilic yeasts — primarily Moniliella pollinis or Trigonopsis variabilis.
The production process begins with cereal starch (typically maize or wheat), which is enzymatically hydrolysed to glucose. The osmophilic yeast accumulates erythritol intracellularly as an osmotic protectant and secretes it into the fermentation medium. After fermentation, the broth undergoes filtration, ion exchange demineralisation, activated carbon decolourisation, evaporation and controlled crystallisation — yielding white crystalline powder at ≥99.5% purity.
This metabolic pathway is the reason the EU officially assigns erythritol 0 kcal/g under Regulation 1169/2011 — not a rounded approximation, but a genuine physiological zero. It is also why the glycaemic index is truly 0, not just low: erythritol does not interact with intestinal glucose transporters (SGLT1, GLUT2) and does not stimulate insulin secretion. The EU health claim confirming this is established in Regulation (EU) 1047/2012.
Structurally, erythritol forms monoclinic crystals with a melting point of 119–121°C and a solubility of approximately 37 g per 100 ml water at 20°C. It has a very low hygroscopicity — it does not readily absorb moisture from the air, unlike sorbitol or maltitol. Its heat of solution is strongly endothermic at approximately −40 J/g, which produces the characteristic cooling sensation when it dissolves on the tongue.
Erythritol is not a perfect sugar substitute in every context — but for specific applications it outperforms every alternative. Here is what the comparison actually looks like.

Every regulatory claim on this page is referenced to its source document. No marketing language. These are the actual decisions from EFSA, the European Commission and the FDA.
Erythritol is authorised as food additive E968 across all EU member states under Regulation (EC) No. 1333/2008 on food additives. It is approved for a broad range of food categories — confectionery, bakery, beverages, dairy, dietary supplements — at quantum satis (no quantity restriction for most categories).
The European Food Safety Authority and the JECFA (FAO/WHO) both assigned erythritol the status “ADI not specified” — meaning no acceptable daily intake limit could be determined because no harmful threshold was identified in any toxicological study. This is the highest safety classification an additive can receive. The only documented adverse effect is osmotic laxation at single doses above approximately 50 g.
The European Commission authorised the health claim: “Erythritol does not raise blood glucose after consumption.” This is a substantiated claim under Article 13(1) of Regulation (EC) 1924/2006, established in Commission Regulation (EU) 1047/2012. It may be used on product labels without minimum quantity conditions.
The second authorised health claim: “Consumption of erythritol-sweetened foods instead of sugar-sweetened foods contributes to the maintenance of tooth mineralisation.” Condition: erythritol must provide at least 10% of the total sweetening effect of the product. Clinical studies confirm erythritol actively inhibits the growth of Streptococcus mutans, the primary caries-causing bacterium.
The United States FDA granted erythritol GRAS (Generally Recognised As Safe) status in 2001. Erythritol is approved for use in food in the USA, Japan, Canada, Australia, Brazil and all EU member states. No country with a modern food regulatory framework has restricted its use.
Multiple randomised controlled trials confirm erythritol’s metabolic neutrality in both healthy subjects and diabetic patients. A 2012 Cochrane-adjacent systematic review found no measurable effect on blood glucose, insulin, triglycerides or HbA1c. Studies in subjects with Type 2 diabetes show equivalent metabolic outcomes to water as the control — a result not achieved by any other polyol.
Erythritol is the most widely used sugar substitute in keto and sugar-free food production — but it behaves differently from sucrose in ways that are critical to know before formulating. Understanding these differences prevents failed batches.
Erythritol provides approximately 70% of sucrose’s sweetness. This means you need 130 g of erythritol to match the sweetness of 100 g of sugar. Critically, the volume and physical bulk remain nearly identical — unlike high-intensity sweeteners such as sucralose or stevia, which are used in parts per million and cannot replace sugar’s structural role in a recipe.
Erythritol is not a reducing sugar. It does not participate in the Maillard reaction — the browning process responsible for the golden crust of baked goods. Products sweetened exclusively with erythritol will be significantly paler than their sugar-based equivalents. Workarounds: add a small amount of milk powder, WPC 80, egg yolk or a touch of honey/maple syrup as Maillard precursors. Alternatively, increase baking temperature by 10–15°C.
Erythritol has a strongly negative heat of solution (−40 J/g). When it dissolves on the tongue, it absorbs heat, creating a cool, minty sensation similar to — but milder than — menthol. In mint chocolate, ice cream, chewing gum and cold beverages, this is a desirable quality that enhances freshness perception. In vanilla cream, warm custard and neutral pastry cream, it can be perceived as off. The solution: reduce erythritol content and supplement with stevioside or sucralose, which have no cooling effect.
This is the most common formulation problem with erythritol. When dissolved in water and cooled, erythritol recrystallises — producing a sandy, gritty texture in frostings, glazes, ganaches and no-bake products. The recrystallisation threshold depends on concentration and cooling rate. Prevention: limit erythritol to 60–70% of the total sweetener blend; add inulin (which inhibits crystal growth), glycerol (which acts as a crystallisation inhibitor) or a small percentage of sucralose/stevia. Keeping the product warm before serving also helps.
Erythritol melts at 119–121°C — well below sugar’s melting point of 185°C. It does not caramelise in the way sucrose does (no brown caramel compounds form). Instead, melted erythritol cools to a white, brittle mass. This makes it unsuitable for genuine caramel production. However, combined with a small amount of sweetened condensed milk or cream, acceptable keto caramel textures can be achieved via the Maillard reaction from the dairy components.
| Application | Dosage | Notes |
|---|---|---|
| Keto chocolate | 80–100 g/100 g cocoa mass | Combine with 10–20% stevioside to reduce cooling effect |
| Keto cookies / biscuits | 130 g per 100 g sugar in recipe | Increase baking temp by 10°C for browning |
| Keto cakes & muffins | 130 g per 100 g sugar | Add 5% inulin to prevent crumbliness |
| Sugar-free beverages | 3–8 g/100 ml | Fully soluble cold; cooling effect enhances citrus/mint |
| Frosting / buttercream | Max 60% of sweetener | Add glycerol or inulin to prevent crystallisation |
| Ice cream & frozen | 8–15 g/100 ml mix | Freezing point depression lower than sucrose → firmer texture |
| Diabetic jam | 80–120 g/kg fruit | Combine with pectin; monitor consistency |
| Chewing gum | 20–40% of gum base weight | Cooling effect is an advantage |
| Tablet / supplement | As needed | Chemically inert; no effect on active ingredients |
| Sugar-free hard candy | Not recommended | Recrystallisation and brittleness are very pronounced |
Not every application is equally well-suited for erythritol. This ranking is based on how well erythritol’s specific properties match each application’s requirements — sweetness, bulk, texture, stability and cost-effectiveness.
Erythritol is the undisputed standard for keto chocolate. It provides the bulk and sweetness of sugar at 1.3:1, it is compatible with cocoa butter and cocoa mass without causing fat bloom, and its mild cooling effect is masked by chocolate flavour. The combination of erythritol + 10–20% stevioside is now the industry standard for >70% of EU keto chocolate products. At 80–100 g per 100 g cocoa mass, the result is indistinguishable in sweetness profile from milk or dark chocolate.
In cold drinks — RTD teas, lemonades, sports drinks, flavoured waters — erythritol dissolves fully at typical concentrations (3–8 g/100 ml) and provides a clean sweetness without aftertaste. The cooling effect is an advantage in citrus and mint variants; neutral in others. GI=0 and 0 kcal enable “zero sugar, zero calorie” label claims.
For foods targeting diabetic consumers, the GI=0 EU health claim makes erythritol the regulatory gold standard. Products can carry the authorised claim “does not raise blood glucose” — a claim no other polyol can make under EU law. Combined with the 0 kcal designation, erythritol enables true “diabetic-suitable” labelling.
Works well in keto baking with correct technique. The 1.3:1 substitution is straightforward; volume and texture are close to the sucrose equivalent. The Maillard deficit is manageable with WPC 80 or egg yolk supplementation. Recrystallisation is not an issue in baked goods that are consumed warm or within 24 hours.
Erythritol lowers the freezing point less than sucrose (due to its molecular weight), producing a firmer frozen texture that holds well in transport. The cooling effect is desirable in frozen applications. It is stable through the pasteurisation step (72°C / 15 s) in ice cream mix production.
Erythritol is chemically inert — it does not react with vitamins, minerals, amino acids or botanical extracts. It acts as a carrier, binder and sweetener in chewable tablets and powder formulations. Its crystalline structure provides good compressibility in direct compression tablet manufacturing.
The recrystallisation problem is most severe in high-fat, cooled sugar systems like buttercream and Swiss meringue buttercream. Without crystallisation inhibitors, erythritol-based frostings become grainy within hours of refrigeration. Requires inulin, glycerol or a significant portion of high-intensity sweetener to remain smooth.
Hard candy relies on boiling a sugar solution to specific temperatures (hard crack stage, 150–160°C) and cooling to a glassy, amorphous state. Erythritol does not produce a stable glassy state — it recrystallises rapidly and produces a brittle, white, opaque mass that shatters rather than forming a clear candy.
Erythritol bulk buyers span multiple industries. The common thread is the need for a high-volume sugar substitute with clean regulatory status and reliable EU supply.
The largest and fastest-growing segment. Keto chocolate, cookies, protein bars and meal replacement products all use erythritol as the primary bulk sweetener. EU keto market was valued at €1.2B in 2024 and growing 18% YoY.
Food companies producing products for diabetic consumers require the EU-authorised GI=0 health claim. Erythritol is often the only sweetener that meets both the regulatory requirements and the volume/texture needs of these products.
Protein bars, pre-workout supplements, recovery drinks and chewable tablets. Erythritol provides sweetness without affecting insulin response — critical for peri-workout nutrition products where insulin management matters.
Sugar-free confectionery: gum, mints, hard-boiled sweets (with isomalt as carrier), chocolate-covered products. Erythritol used as part of blend, often with maltitol or isomalt for texture.
RTD teas, flavoured waters, soft drinks, energy drinks and functional beverages targeting zero-sugar positioning. Erythritol provides body and mouthfeel that high-intensity sweeteners cannot match.
Tablet manufacturers, capsule fillers, chewable supplement producers. Erythritol used as carrier, binder and sweetener. Regulatory neutrality and chemical inertness are key requirements.
