Choosing the right high-intensity sweetener is a delicate balancing act of taste, stability, cost and regulatory status. Here is a practical comparison to help formulators make an informed choice.
The main players
1. Sucralose
- ~600× sweeter than sugar
- Excellent thermal stability for baking and processing
- Clean taste with minimal aftertaste
2. Aspartame
- ~200× sweeter, clean sugar-like taste
- Not heat stable; loses sweetness when heated
3. Stevia extract
- Natural plant origin, zero calories
- Can carry a licorice-like aftertaste
4. Acesulfame K
- ~200× sweeter, heat stable
- Often blended with other sweeteners
How to choose
- Match sweetness profile to the product category
- Consider heat and pH stability for the application
- Blend two or more sweeteners for an optimised, sugar-like taste
- Keep cost-in-use and regulatory status in mind
For many applications, sucralose offers the best all-round balance of taste, stability and versatility — especially when blended to fine-tune flavour.
