Erythritol (CAS 149-32-6), chemically identified as (2R,3S)-butane-1,2,3,4-tetrol, is a four-carbon sugar alcohol functioning as a non-caloric bulk sweetener and taste modifier in functional food and beverage formulation. This crystalline polyol, also technically referred to as meso-erythritol or tetrahydroxybutane, acts as a bulking agent with high digestive tolerance to replace sucrose in low-glycemic and keto-friendly product lines. We provide bulk supply of this food-grade ingredient with competitive factory pricing to optimize production costs for confectionery manufacturers. Our quality management system ensures high purity standards, making MSDS, TDS, COA available alongside customized specifications to meet specific mesh size or granulation needs.

Product Description
Erythritol is a high-purity, fermented polyol widely used as a zero-calorie bulk sweetener in food, beverage and nutraceutical formulations. It offers about 60–70% of the sweetness of sucrose, with a clean taste, excellent digestive tolerance and no impact on blood glucose or insulin levels. Thanks to its high thermal and pH stability, it is suitable for a wide range of processing conditions from baked goods to RTD drinks.

Applications
1. Food & Beverage (Sugar Reduction / Replacement)
- Used as a bulk sweetener in sugar-free or reduced-sugar beverages, flavored water, energy drinks and dairy products.
- Helps to reduce calories while maintaining mouthfeel and sweetness when blended with high-intensity sweeteners (e.g. sucralose, stevia, acesulfame K).
2. Confectionery & Bakery
- Ideal for sugar-free candies, mints, chewing gum, chocolate, coated nuts and snack bars.
- Thermal stability makes erythritol suitable for baked products such as biscuits, cakes, muffins and pastries, helping to control Maillard browning and extend shelf life.
3. Table-Top & Blended Sweeteners
- Commonly used as the main carrier in tabletop sweetener formulations mixed with stevia, monk fruit or sucralose to provide a sugar-like taste and bulk.
- Good flowability and low hygroscopicity support convenient packing into sticks, sachets and tablets.
4. Nutrition, Health & Special Diet Products
- Widely used in “keto”, “diabetic-friendly” and “sports nutrition” products due to zero glycemic response.
- Suitable for bars, protein products and powdered drink mixes where calorie control and taste are both critical.
5. Pharmaceutical & Personal Care
- Serves as a non-cariogenic sweetener and filler in oral dosage forms (orodispersible tablets, lozenges, chewable tablets).
- Applied in toothpaste and mouthwash for pleasant sweetness and cooling sensation without promoting tooth decay.
For other bulk carbohydrate-based sweetener or carrier raw materials, see Mannitol and Maltodextrin.
Storage Conditions
To maintain quality and extend shelf life, erythritol should be stored under the following conditions:
- Keep the product in its original, tightly sealed packaging.
- Store in a cool, dry, well-ventilated warehouse, away from direct sunlight and heat sources.
- Avoid high humidity and strong odors; erythritol can absorb odor molecules from the environment.
- Do not stack excessively to avoid packaging damage and caking.
Safety Precautions
- Erythritol is generally recognized as safe (GRAS) for use in foods and is approved by major international regulations for standard use levels.
- Handle as a food ingredient: avoid contamination, and respect local hygiene standards during processing and packing.
- High intake in a short time may cause mild gastrointestinal discomfort in sensitive individuals; it is recommended to follow local guidance on daily intake for sugar alcohols.
- Avoid creating excessive dust during handling and transfer, as dust may cause mechanical irritation to eyes and respiratory tract and, in extreme cases, may pose a dust explosion risk.
- Personal protection: use dust masks, gloves and eye protection where appropriate. Wash hands after handling.
In case of contact:
- Eye contact: Rinse thoroughly with clean water for several minutes. Seek medical advice if irritation persists.
- Inhalation of dust: Move to fresh air; seek medical attention if discomfort continues.
- Ingestion: Erythritol is a food-grade material; no special measures are required beyond drinking water if discomfort occurs.
FAQ - Technical & Supply Chain
-
Q:
What is Erythritol CAS 149-32-6?
A: 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. -
Q:
How is food-grade Erythritol produced?
A: 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. -
Q:
Is Erythritol suitable for keto and diabetic-friendly products?
A: 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. -
Q:
What are the main applications of Erythritol?
A: It is used in sugar-free beverages, confectionery, chewing gum, chocolate, bakery products, dairy products, tabletop sweetener blends, sports nutrition, and oral-care or pharmaceutical products. It also works well as a bulk carrier for stevia, monk fruit, or sucralose. -
Q:
Can Erythritol be used in baking and heat-processed foods?
A: 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. -
Q:
How should Erythritol be stored and handled?
A: 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.
