What Is Erythritol?

Check out this answer from Consensus:

Erythritol is a versatile and beneficial sugar alcohol with applications in various industries. Its production has been optimized through biotechnological advancements, and its health benefits, particularly for diabetics and those managing obesity, are well-documented. While further research is needed to fully understand its long-term effects, current evidence suggests that erythritol is a valuable low-calorie sweetener with multiple potential applications1 2 3 4 5 6 7 8 9 10.

Erythritol is a sugar alcohol that has gained popularity as a low-calorie sweetener. It is naturally found in various fruits and vegetables and is also produced commercially through fermentation processes. This article explores the production, metabolism, health effects, and potential applications of erythritol.

Production of Erythritol

Erythritol is produced by microorganisms as an osmoprotectant and is commonly used in the food and pharmaceutical industries. Industrial production typically involves the fermentation of sugars by specific yeasts, such as Moniliella sp. and Yarrowia lipolytica, which can utilize low-cost substrates to improve yield and productivity2 4 5. Recent advancements in metabolic engineering have further optimized the production process, making erythritol a more viable commercial product2 5.

Metabolism and Absorption

Erythritol is absorbed in the small intestine and excreted unchanged in the urine, which makes it better tolerated than other sugar alcohols. It does not significantly affect blood glucose or insulin levels, making it a suitable sweetener for diabetics and those managing obesity1 7. Studies have shown that erythritol is metabolized into erythronate in a dose-dependent manner, although the health implications of this metabolization are still under investigation7.

Health Effects

Safety and Tolerance

Erythritol is generally well-tolerated and does not cause significant gastrointestinal distress, unlike other sugar alcohols. It is almost fully absorbed and excreted, which minimizes its impact on the digestive system1.

Impact on Weight and Metabolism

Long-term studies in rodents have shown that erythritol consumption can lower body weight and adiposity. However, observational studies in humans have indicated a positive association between plasma erythritol levels and obesity and cardiometabolic diseases. This association is likely due to dysregulated glucose metabolism rather than the direct effects of dietary erythritol1 3.

Diabetes Management

Erythritol has been shown to inhibit α-glucosidase, an enzyme involved in carbohydrate digestion, thereby attenuating postprandial blood glucose levels. This makes it a promising agent for managing diabetes mellitus8.

Applications

Food Industry

Erythritol is widely used as a sweetener in calorie-reduced foods, candies, and bakery products. Its low-calorie content and minimal impact on blood glucose levels make it an attractive alternative to traditional sugars4 9.

Pharmaceutical Industry

Due to its unique nutritional properties, erythritol is also used in special foods for people with diabetes and obesity. It serves as an inexpensive starting material for the production of other sugars5.

Pest Control

Interestingly, erythritol has shown promise as an organic, human-safe insecticide. It has been effective in controlling pest mites while being minimally harmful to predatory mites, making it a potential component of integrated pest management (IPM) strategies6.
