Product Overview

Acesulfame Potassium, often called Ace-K, is a widely used calorie-free high-intensity sweetener. With CAS number 55589-62-3, E;950, it is commonly used in food, beverage, confectionery, pharmaceutical and cosmetic industries as a sugar alternative.

Ace-K is approximately 200 times sweeter than sucrose. It provides strong sweetness with low usage levels and is suitable for reduced-sugar, sugar-free and calorie-controlled product formulations.

Key Characteristics

High sweetness intensity — about 200 times sweeter than sucrose, low dosage required

Excellent thermal stability — suitable for baking, sterilization and high-temperature processing

Wide pH stability — stable in both acidic and neutral food systems

Fast sweetness onset — quick sweet taste with no lingering aftertaste when blended properly

Synergistic effect — blends well with aspartame, sucralose and other sweeteners to improve overall taste

Long shelf life — chemically stable, does not degrade during storage

 

Core Functions

1. High Sweetness: Acesulfame Potassium is about 200 times sweeter than sucrose. High sweetness allows low inclusion levels, making it suitable for sugar-free and reduced-calorie formulations.

2. Calorie Free: Ace-K provides sweetness without calories. It is widely used in diet beverages, zero-sugar drinks, sugar-free food and calorie-controlled products.

3. Good Stability: Acesulfame Potassium is stable in many food processing environments. It can be used in beverages, confectionery, dairy products and pharmaceutical formulations.

4. Sugar Alternative: Ace-K acts as a sugar alternative in industrial production. It helps manufacturers reduce sugar content while maintaining sweet taste and product performance.

 

Main Application Fields

 

Beverage Industry: Acesulfame Potassium is widely used in carbonated drinks, juice drinks, diet beverages, zero-sugar drinks and dairy products as a calorie-free sweetener.

Food & Confectionery: Used in sugar-free food, confectionery, chewing gum, jams, desserts and baked goods as a sugar alternative.

Pharmaceutical Industry: Applied in pharmaceutical formulations, tablets, syrups, oral solutions and medicinal products as a sweetener and flavor modifier.

Other Applications: Acesulfame Potassium can also be used in oral care products, cosmetics and industrial sweetener formulations.
