Application

Erythritol serves as a versatile low-calorie sweetener with approximately 60-70% of the sweetness of sucrose, offering a pleasant taste and a strong cooling effect due to its high negative heat of solution. This sugar alcohol is non-cariogenic and used widely in both food and pharmaceutical applications. As an excipient, erythritol functions in various pharmaceutical preparations such as tablet fillers, coatings, and dry powder inhalers. Its cooling properties make it ideal for products like sugar-free lozenges and medicated chewing gum. Furthermore, erythritol is valued in moisture-sensitive drug formulations as a diluent in wet granulation processes. In addition to its role in providing sweetness without calories, it is utilized in syrups to modify sensorial profiles and mask unwanted aftertastes. Erythritol is also a preferred choice in oral care products like toothpastes and mouthwash solutions for its sweetening properties and oral health benefits.
