Sugar substitute

language culture Maturity 11-13 Next article →

Sugar substitutes, also known as artificial sweeteners, are food additives designed to provide sweetness. They offer a taste similar to sugar but contain significantly less food energy. This characteristic makes them zero-calorie or low-calorie options. They are used to help people manage their weight and blood glucose levels. Many people use them in diet drinks to avoid adding extra calories. These substances can be derived from plant extracts or created through chemical synthesis.

Scientists categorize these substances into different functional types. High-intensity sweeteners are compounds that are many times sweeter than sucrose, which is common table sugar. Because they are so potent, only a tiny amount is needed for sweetness. This results in a negligible energy contribution to the food. Sometimes these compounds create a different sensation of sweetness than sucrose. To fix this, manufacturers often use complex mixtures to achieve a more intense, sucrose-like sensation.

Another major group includes sugar alcohols, also known as polyols. Examples of these include erythritol, xylitol, and sorbitol. These are derived from sugars but are generally less sweet than sucrose. However, they possess similar bulk properties to sugar, which is useful in food production. Sometimes, their sweetness profile is fine-tuned by mixing them with high-intensity sweeteners. There is also allulose, a sweetener in the sugar family found in figs and maple syrup. It is about 70% as sweet as sugar but does not metabolize like sugar in the body.

Acesulfame potassium, or Ace-K, is a specific type of high-intensity sweetener. It is 200 times sweeter than sucrose and roughly as sweet as aspartame. Like saccharin, it can have a slightly bitter aftertaste at high concentrations. To solve this, Kraft Foods patented the use of sodium ferulate to mask the taste. Ace-K is often blended with aspartame or sucralose to create a synergistic effect. This means the blend becomes even sweeter than its individual parts. Unlike aspartame, Ace-K is stable under heat and acidic conditions, making it ideal for baking.

Many famous sweeteners were discovered through accidental scientific moments. In 1879, Remsen and Fahlberg discovered saccharin during an experiment with toluene derivatives. It was the first artificial sweetener ever synthesized. In 1965, James M. Schlatter discovered aspartame while working on an anti-ulcer drug. He accidentally spilled the substance on his hand and noticed a sweet taste when he licked his finger. Torunn Atteraas Garin then oversaw the development of aspartame for commercial use. Aspartame is a white crystalline powder made from the amino acids aspartic acid and phenylalanine.

Different sweeteners are subject to different international regulations and safety studies. In the United States, cyclamate is prohibited because of lab tests involving rats. However, cyclamate is still allowed in Canada, Russia, and the European Union. Saccharin faced similar scrutiny after a 1960 study suggested a link to bladder cancer in rats. Scientists later found this mechanism is not relevant to humans due to differences in urine composition. In 2001, the United States repealed the warning label requirement for saccharin. Most other countries permit its use but may restrict the allowed levels.

Sucralose is currently the most commonly used artificial sweetener in the world. It was discovered in 1976 and received FDA approval in 1998. It is a chlorinated sugar produced by replacing three hydroxyl groups in sucrose with three chlorine atoms. This chemical change makes it about 600 times sweeter than sugar. A major advantage of sucralose is its stability when heated. This allows it to be used in baked goods and fried foods. It is found in many products, including beverages, frozen desserts, and chewing gum.

Sweeteners play a vital role in modern food science and pharmaceutical industries. Beyond tabletop packets, they are used in protein shakes and liquid medications. In medicine, they make active ingredients more palatable for patients. Stevia is another important example, derived from the Stevia rebaudiana plant. While it was once banned by the FDA in 1987, it gained "generally recognized as safe" status in 2008. Today, these diverse substances allow for a wide range of sweet experiences across many different cultures and food systems.
