Wholesale Pure Erythritol Powder
What is erythritol?
Erythritol is a zero-calorie, delicious bulk sweetener suitable for a variety of sugar-free and reduced-calorie foods and beverages. Erythritol has been a part of the human diet for thousands of years and is found in fruits and other foods.
Erythritol is highly digestible and does not cause a glycemic response, making it suitable for diabetics. It also does not promote tooth decay. Erythritol is a polyol (sugar alcohol) naturally found in fruits such as pears, melons, and grapes. It can also be found in other foods such as mushrooms, as well as in wine, soy sauce, and cheese.
Erythritol is a white crystalline powder with a pure, refreshing sweetness, similar to that of sucrose. Erythritol has approximately 70% the sweetness of sucrose and, because it is non-hygroscopic, has good flowability. With a caloric value of 0 calories per gram, erythritol's high digestibility distinguishes it from other polyols. Erythritol is rapidly absorbed by the small intestine and digested by the body within 24 hours, so when consuming foods containing erythritol, the laxative side effects that may occur when consuming excessive amounts of polyols are unlikely to occur.
Characteristics of Erythritol
Low Sweetness
Erythritol has only 60%-70% the sweetness of sucrose. It has a refreshing, pure flavor with no aftertaste. It can be combined with high-intensity sweeteners to suppress the unpleasant flavors of these high-intensity sweeteners.
High Stability
It is extremely stable to acid and heat, with high acid and alkali resistance. It does not decompose or change at temperatures below 200°C, and does not undergo the Maillard reaction that causes discoloration.
High Heat of Dissolution
Erythritol absorbs heat when dissolved in water. Its heat of dissolution is only 97.4 kJ/kg, higher than that of glucose and sorbitol, resulting in a refreshing sensation when consumed.
Solubility
The solubility of erythritol at 25°C is 37% (w/w). Its solubility increases with increasing temperature, making it less likely to crystallize.
Low Hygroscopicity
Erythritol crystallizes easily, but it remains hygroscopic even in 90% humidity. It can be easily crushed into a powder, making it suitable for use on food surfaces to prevent moisture absorption and spoilage.
Functions of Erythritol
Glycolipid Metabolism
Glycolipid metabolism is a vital process for cells and the body as a source of material and energy. Imbalances in glucose and lipid metabolism can lead to various diseases and impact human health. Because the human body lacks the enzymes required to metabolize erythritol, most of the erythritol that enters the body is excreted in the urine. Its metabolic pathway is independent of, or minimally dependent on, insulin. In healthy individuals, single or repeated intakes of erythritol do not affect blood glucose, lipid profiles, or glucose tolerance. Specifically, a single recommended oral dose of erythritol (0.3-0.8 g/kg) does not affect blood glucose, lipid profiles, insulin, or glucagon levels. Even higher doses of erythritol (1 g/kg) do not elevate plasma insulin or blood glucose levels. Consuming foods containing erythritol is relatively safe for individuals with sugar restrictions, such as those with diabetes. Studies on diabetes have even shown that erythritol not only maintains blood glucose and lipid homeostasis in patients with type 2 diabetes and impaired glucose tolerance, but also has the potential to lower blood glucose. However, one study showed that erythritol consumption increased free fatty acid and 3-hydroxybutyrate levels, but these levels decreased after a meal. This phenomenon may be due to the fact that erythritol provides little energy and the subjects were starving.
Oxidative Stress
Erythritol has antioxidant activity, effectively scavenging free radicals in the body and inhibiting their production, helping to prevent hyperglycemia-induced vascular damage. Oxidative stress results from an imbalance between the oxidative and antioxidant systems in cells and tissues, primarily due to increased production and/or decreased scavenging capacity of reactive oxygen species. Erythritol is not only an effective free radical scavenger and inhibitor but also possesses endothelial protective properties. Erythritol exhibits strong vascular protective effects under conditions of hyperglycemia, likely due to its antioxidant properties.
Low Caloric Value
Compared to other sweeteners, erythritol is a very low-energy sweetener, with a caloric value of approximately 1.25 kJ/g, roughly one-tenth that of sucrose. This is because the human body lacks the enzymes to metabolize erythritol. Once it enters the bloodstream, erythritol cannot be digested and degraded, and must be excreted in the urine through the kidneys. This unique metabolic characteristic contributes to erythritol's low calorie value. Therefore, erythritol, alone or mixed with other sweeteners, can be used as a sucrose replacement to create low-calorie health supplements suitable for those suffering from obesity, hypertension, and cardiovascular disease. The US Food and Drug Administration defines its caloric value as 0.2 kcal/g, while some countries, such as Japan, define it as 0 kcal/g. Therefore, erythritol is also known as a zero-calorie food.
Non-cariogenic
Caries are primarily caused by oral carbohydrate substrates, which ferment under the action of bacteria, particularly Staphylococcus aureus, to produce acid. This acid deionizes and damages tooth enamel, thus inducing caries. However, erythritol is not utilized by oral bacteria, nor is it fermented by oral enzymes to produce acid. Therefore, erythritol has strong caries-fighting properties. Promotes Bifidobacterium Growth
A study using 72 strains of 49 species of intestinal bacteria from 12 genera examined the utilization of erythritol by intestinal bacteria. The results showed that these bacteria were poorly utilized by erythritol. However, erythritol significantly promotes the growth of bifidobacteria in the intestines. The short-chain fatty acids (acetic acid and lactic acid) produced by bifidobacteria metabolism can effectively inhibit the growth of pathogens, thereby enhancing the body's immunity.
Does not cause blood sugar fluctuations
Erythritol is absorbed by the small intestine through passive diffusion. Most of the ingested erythritol enters the bloodstream, with only a small amount entering the large intestine. Once in the bloodstream, erythritol cannot be broken down by enzymes in the body and is excreted through the kidneys and urine. Once in the large intestine, erythritol is difficult to ferment and utilize by bacteria, so it does not cause fluctuations in blood sugar and insulin levels, making it suitable for diabetic patients.
High Tolerance, Minimal Side Effects
Extensive animal and clinical trials have demonstrated that erythritol is safe, non-toxic, non-teratogenic, does not cause chromosomal mutations, does not affect reproduction and development, is non-carcinogenic, and does not stimulate tumor growth. It is well tolerated by the digestive tract, has no significant metabolic effects on diabetic patients, and has no side effects on blood sugar control. Because 80% of erythritol that enters the body is rapidly absorbed by the small intestine, avoiding the potential side effects of unabsorbed substances, such as diarrhea and flatulence, erythritol is highly tolerable, making it the most tolerable of all sugar alcohols. Since only a small amount enters the large intestine, and 50% is excreted, the amount retained in the intestine is minimal, resulting in minimal side effects.
Applications of Erythritol
Erythritol has a wide range of applications in the food industry. It can be used as a sweetener for diabetics and those seeking to control their sugar intake in products such as chocolate, chewing gum, fudge, and sponge cakes. It can also be used in organic synthesis as a raw material for alkyd resins, polyesters, and polyethers, and in the production of nitroerythritol, a drug for treating cardiovascular and cerebrovascular diseases and asthma.
Food Industry
Due to its favorable properties, erythritol is often used as a diluent for low-calorie or high-intensity sweeteners in candy, dairy products, beverages, alcoholic beverages, baked goods, soft drinks, and solid beverages. It is also widely used in dairy products, ice cream, pastries, and tabletop sweeteners.
In candy and chocolate, erythritol can replace sucrose, providing a pure sweetness and refreshing taste without the need for strong sweeteners like aspartame or saccharin. It can also be used synergistically with other sugar alcohols to improve tolerability. High-purity crystalline erythritol powder can enhance the quality and taste of finished products.
In beverages, erythritol is used in zero- or low-calorie drinks and can extend the shelf life of fermented dairy products. It enhances sweetness, body, and smoothness, reduces bitterness, and masks other odors. Its heat-absorbing properties make it suitable for refreshing solid beverages and can improve the flavor and quality of alcoholic beverages. It can also significantly reduce the unpleasant off-flavors of substances such as collagen and peptides.
In baked goods, erythritol can replace sucrose and oils, meeting modern low-calorie and health-conscious trends. It offers physical and chemical properties similar to sucrose while creating a tighter, softer structure and slightly different color. Powdered or finely granulated erythritol (≤200μm) is recommended for a better taste.
In cakes and biscuits, erythritol can reduce calories, extend shelf life, inhibit microbial growth, and maintain product freshness and softness. Adding 10% erythritol to biscuits improves stability and shelf life. Adding it to cream icings reduces calories and provides a refreshing taste. When used in combination with maltitol solution and aspartame, it can reduce calories by nearly 50%. Adding fine erythritol to cream-based cakes and sandwich cookies can reduce calories, provide a refreshing taste, and extend shelf life.
Pharmaceutical Industry
Erythritol can be used as a coating ingredient to improve tablet stability, enhance appearance, and mask unpleasant odors. Its low hygroscopicity and rapid crystallization make it an excellent alternative to sugar coatings. Erythritol can also be used as a tablet excipient, suitable for direct compression processes. It is a good flavoring agent and is low in hygroscopicity. Furthermore, it can be used as a carrier or excipient in dry powder inhalers, improving drug dispersion and inhalation efficiency, allowing the drug to reach the lungs and take effect more easily.
