What is Erythritol CAS 149-32-6?

Erythritol is a four-carbon sugar alcohol with the molecular formula C₄H₁₀O₄. It is a white crystalline powder or granule that provides about 60-70% of the sweetness of sucrose, with about 0.2 kcal/g and a glycemic index of 0.

How is food-grade Erythritol produced?

Food-grade Erythritol is normally produced by microbial fermentation of a carbohydrate substrate, followed by purification, crystallization, and drying. This fermentation route is preferred for commercial production and provides a clean-tasting, high-purity polyol.

Is Erythritol suitable for keto and diabetic-friendly products?

Yes. Erythritol is widely used in keto, low-carb, and diabetic-friendly foods because it is absorbed and excreted without being fully metabolized, so it has a negligible effect on blood glucose and insulin levels. Formulators should still follow local food regulations for the intended market.

Can Erythritol be used in baking and heat-processed foods?

Yes. Erythritol has good thermal stability and does not readily participate in Maillard browning, so it can be used in baked and heat-processed foods. Because it is less sweet than sucrose and has a cooling effect, the recipe and other sweeteners may need to be adjusted.

How should Erythritol be stored and handled?

Keep it in tightly closed, moisture-protected packaging in a cool, dry, well-ventilated area away from strong odors and direct sunlight. Use standard food-ingredient hygiene, avoid excessive dust generation, and reseal opened packages promptly after use.

Product Description

Erythritol, CAS 149-32-6, also known as meso-erythritol or 1,2,3,4-butanetetrol, is a four-carbon sugar alcohol; the EC/EINECS number is 205-737-3.

Synonyms: meso-erythritol; (2R,3S)-butane-1,2,3,4-tetrol; 1,2,3,4-butanetetrol; tetrahydroxybutane; butane-1,2,3,4-tetrol.

CAS: 149-32-6.

Molecular formula: C₄H₁₀O₄.

Molecular weight: 122.12 g/mol.

EC number: 205-737-3.

It is a white, free-flowing crystalline powder or granule, odorless, with a clean sweet taste and a slight cooling effect.

The assay (on dry basis) is typically ≥99.5%; a 20% aqueous solution at 25 °C has a pH of 5.0–7.0.

Moisture (loss on drying) is ≤0.20%, residue on ignition ≤0.10% and heavy metals (as Pb) ≤5 ppm; the melting point is 119–123 °C.

It is used as a zero-calorie bulk sweetener in sugar-free beverages, confectionery, chewing gum, chocolate, bakery and dairy products.

It is used as a carrier and bulking agent in tabletop sweetener blends, sports nutrition and oral-care or pharmaceutical products.

It provides about 60–70% of the sweetness of sucrose with negligible glycemic response, making it suitable for keto, low-carb and diabetic-friendly products.

It is produced by microbial fermentation of a carbohydrate substrate, followed by purification, crystallization and drying to a high-purity polyol.

Confirm assay, particle size, moisture, ash, heavy metals, reducing sugars and microbial limits; select the food or high-purity grade and specify the application.

Store in tightly closed, moisture-protected packaging in a cool, dry, well-ventilated area away from strong odors and direct sunlight; reseal promptly after use.

Confirm packaging with the requested quantity and destination requirements.

Document requirements should be confirmed from the current specification, SDS, COA or other product-specific files.
