What is Aspartame?
Aspartame is an artificial, high-intensity sweetener that is derived from two naturally occurring amino acids, aspartic acid and phenylalanine. Because aspartame is about 200 times sweeter than regular sugar, only a tiny amount is needed to achieve the desired level of sweetness. Although it contains calories (four per gram, similar to sugar), the amount used in Equal is so small that it is considered a zero-calorie sweetener per serving.
Aspartame is widely approved by regulatory bodies, including the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA), for use as a food additive. However, it is not heat-stable and loses its sweetness when exposed to high temperatures. For this reason, Equal is not typically recommended for baking and is best used for sweetening beverages or foods after the cooking process. Products containing aspartame must carry a warning for individuals with phenylketonuria (PKU), a rare genetic disorder that affects the body's ability to process phenylalanine.
The Role of Acesulfame Potassium
Original Equal packets and tablets also contain acesulfame potassium (Ace-K), another zero-calorie artificial sweetener. Ace-K is also around 200 times sweeter than sugar and is often blended with other sweeteners to create a more sugar-like taste profile and avoid any potential bitter aftertaste. Unlike aspartame, acesulfame potassium is heat-stable, making it suitable for a wider range of food applications. In Equal, the combination of aspartame and acesulfame potassium provides a balanced, clean sweetness.
Comparison of Popular Sweeteners
To better understand Equal's composition, here is a comparison with other common sugar substitutes:
| Feature | Equal (Aspartame/Ace-K) | Splenda (Sucralose) | Sweet'N Low (Saccharin) | Stevia (Steviol Glycosides) |
|---|---|---|---|---|
| Primary Sweetener | Aspartame, Acesulfame Potassium | Sucralose | Saccharin | Rebaudioside A (from Stevia plant) |
| Calorie Content | Zero-calorie per serving | Zero-calorie per serving | Zero-calorie per serving | Zero-calorie per serving |
| Sweetness (vs. Sugar) | ~200 times | ~600 times | ~200-700 times | ~200-400 times |
| Best Uses | Hot/cold beverages, sprinkling on food. Not recommended for baking. | Cooking, baking, and beverages due to heat stability. | Baking, beverages, processed foods. | Beverages and baking, often blended with sugar alcohols. |
| Heat Stability | Low (Aspartame degrades) | High | High | High |
History and Controversy
Aspartame was discovered in 1965 by chemist James Schlatter and received FDA approval for use as a tabletop sweetener in 1981. Equal was subsequently introduced to the U.S. market in 1982. Despite its widespread use, aspartame has been a subject of controversy and public concern regarding its safety. These concerns have led to numerous studies over several decades, with regulatory bodies consistently affirming its safety for consumption within acceptable daily intake (ADI) levels. However, some individuals report side effects, and further research into potential long-term effects continues.
The Role of Other Ingredients
To make the highly concentrated sweeteners easier to measure and use, Equal includes other ingredients in its formulation. These are often referred to as 'fillers' or 'bulking agents'. In the case of Equal packets, dextrose and maltodextrin are used. Tablets use a different formulation, often including lactose. These ingredients are also carbohydrates, but the total amount in a single packet is minimal, allowing the product to be marketed as having zero calories per serving.
Conclusion
In summary, Equal is a brand of artificial sweetener whose key component is aspartame, often blended with acesulfame potassium for a better taste profile. While it offers a low-calorie alternative to sugar, it is not suitable for high-heat applications like baking due to aspartame's instability. It is important for individuals with phenylketonuria (PKU) to avoid it due to the phenylalanine content. As with any sugar substitute, its use should be part of a balanced diet, and individuals should be mindful of other ingredients in products sweetened with Equal.
