Understanding the Sweetness Scale
When comparing sweeteners, the standard unit of measurement is the sweetness level relative to sucrose (table sugar), which is given a reference value of 1.0. Intense sweeteners far surpass this benchmark, offering a high perceived sweetness without the caloric content. This is due to their chemical structure, which interacts with the sweet taste receptors on the tongue with much greater efficiency.
The Highest Sweetness Sweetener: Advantame
Advantame is an artificial, high-intensity, non-nutritive sweetener developed by Ajinomoto. It is created from aspartame and vanillin, an extract from the vanilla bean. What makes Advantame stand out is its extraordinary sweetness potency, which is rated at approximately 20,000 times that of sugar, though some ranges vary slightly. It was approved by the U.S. Food and Drug Administration (FDA) in 2014 for use as a general-purpose sweetener and flavor enhancer. A significant advantage of Advantame is its high thermal stability, meaning it remains sweet even when subjected to high temperatures during cooking and baking, unlike its precursor, aspartame. The extremely small amounts required for sweetening mean that it contributes negligible calories, making it a valuable tool for reducing sugar and calorie content in a wide range of foods and beverages.
Other High-Intensity Sweeteners
While Advantame holds the record for potency among approved sweeteners, several others are well-known for their intense sweetness.
Neotame
Neotame is another aspartame analog, but it is much sweeter than regular aspartame due to a modification process. Its sweetness is rated between 7,000 and 13,000 times that of table sugar, depending on the application. Neotame is also heat-stable and can be used in cooked and baked products. Unlike aspartame, it does not require a warning label for people with phenylketonuria (PKU) because it releases very little phenylalanine during digestion.
Thaumatin
Thaumatin is a natural, protein-based sweetener extracted from the katemfe fruit of West Africa. This intensely sweet protein is approximately 2,000 to 3,000 times sweeter than sucrose. While potent, it is also highly valued for its flavor-modifying properties and is often used in combination with other sweeteners to improve the overall taste profile.
Sucralose
Sucralose, commonly known by the brand name Splenda®, is an artificial sweetener derived from a sugar molecule. It is about 600 times sweeter than table sugar and is calorie-free. Sucralose is heat-stable and versatile, making it suitable for a vast array of food and drink products.
Steviol Glycosides (Stevia)
Steviol glycosides are a family of natural, plant-based sweeteners extracted from the leaves of the Stevia rebaudiana plant. These compounds are 200 to 400 times sweeter than sugar and are widely used in a variety of foods and beverages. Some consumers prefer it for its natural origin, though it can have a slight aftertaste depending on the specific glycoside used.
Comparison of High-Intensity Sweeteners
| Sweetener | Type | Relative Sweetness (vs. Sucrose) | Common Brands (Examples) | Heat Stability | Aftertaste | Special Notes |
|---|---|---|---|---|---|---|
| Advantame | Artificial | ~20,000x | Advantame® | Excellent | Minimal | Derived from aspartame and vanillin. |
| Neotame | Artificial | 7,000-13,000x | Newtame® | Excellent | Minimal | Modified aspartame; no PKU warning required. |
| Thaumatin | Natural | 2,000-3,000x | Talin® | Excellent | Licorice-like | Primarily a flavor modifier; a protein. |
| Sucralose | Artificial | ~600x | Splenda® | Excellent | Minimal | Made from sugar molecule. |
| Steviol Glycosides | Natural | 200-400x | Truvia®, PureVia® | Good | Sometimes bitter | Extracted from the stevia plant. |
| Aspartame | Artificial | ~200x | NutraSweet®, Equal® | Poor | Minimal | Not suitable for baking; contains phenylalanine. |
Choosing the Right Sweetener
Selecting a sweetener depends on several factors beyond just maximum sweetness. Considerations include:
- Flavor profile: Some high-intensity sweeteners, particularly at high concentrations, can have a noticeable aftertaste. Blends are often used to create a more balanced, sugar-like taste.
- Application: Heat-stable options like Advantame and sucralose are ideal for baked goods, while less stable ones like aspartame are better suited for products that are not heated.
- Nutritive vs. Non-nutritive: Most intense sweeteners are non-nutritive (zero-calorie). However, some, like certain sweet proteins (e.g., Brazzein), technically provide calories but are used in such small amounts that the caloric contribution is negligible.
- Origin: Natural (stevia, monk fruit) versus artificial (Advantame, sucralose) is a common deciding factor for many consumers based on personal preference.
- Dietary Restrictions: Individuals with phenylketonuria must avoid aspartame, but its derivative, neotame, is safe for them.

Conclusion
In the world of sweeteners, Advantame reigns supreme with the highest sweetness potency, offering an astonishing 20,000 times the sweetness of sugar. Its stability and clean taste make it a superior choice for many food and beverage applications. However, the market is rich with other options, each with unique properties that cater to different needs. Understanding these differences, from the intensely potent Advantame and Neotame to the more familiar Sucralose and natural Stevia, allows for informed decisions regarding taste, application, and overall health goals.
