Acesulfame Potassium (Acesulfame-K)
CAS Number: 55589-62-3
Acesulfame potassium (Ace-K, E950) is a high-intensity sweetener approximately 200 times sweeter than sucrose with a clean, fast sweetness onset. It is calorie-free, heat-stable up to 225°C, and pH-stable across the range 3–7, making it ideal for baking, hot beverages, and carbonated drinks. Typically blended with aspartame or sucralose (50/50) to achieve superior sweetness quality and synergistic dose reduction.
