Product Overview

Erythritol (E968, CAS 149-32-6) is a low-calorie polyol sweetener with negligible calories and non-cariogenic property. It delivers clean refreshing sweetness and maintains stability under high temperature. It is widely used in confectionery, chewing gum, bakery, beverages and oral care products.

Key Characteristics

1.Very low calorie content, only about 0.2 kcal/g, suitable for low-sugar and sugar-free formulas

2.Non-cariogenic, cannot be fermented by oral bacteria to produce acid

3.Clean refreshing taste with cooling sensation, no bitter or metallic aftertaste

4.Good thermal stability, suitable for baking, hot filling and sterilization processes

5.Low osmotic pressure, milder on digestion compared to other polyols

6.Blends well with high-intensity sweeteners to mask off-notes and improve taste profile

Main Functions

Low Calorie Sweetener: Provides sweetness with minimal caloric contribution, ideal for sugar-free and low-calorie product development.

Non-Cariogenic Agent: Protects dental health by resisting acid fermentation in the oral cavity.

Taste Improver: Delivers clean, cooling sweetness and blends with other sweeteners to optimize overall taste.

Heat-Stable Sweetener: Maintains sweetness under high-temperature processing such as baking and sterilization.

Digestive-Friendly Polyol: Lower osmotic pressure causes less gastrointestinal discomfort than other sugar alcohols.

Applications

Sugar-free Chewing Gum & Confectionery Core application, widely used in sugar-free chewing gum, hard candies, soft candies, chocolates and mints.

Baked Goods Applied in cookies, cakes, pastries and bread as a sugar replacement with good thermal stability.

Beverages Used in sugar-free drinks, bottled teas, functional beverages and flavored water.

Dairy & Desserts Applied in yogurt, ice cream, low-calorie desserts and protein bars.

Oral Care Products Added to toothpaste, mouthwash and breath freshening products.

Dietary Supplements Used in sports nutrition products and weight-management formulations.
