First, bacteria which produce the appropriate amino acids are cultivated in large quantities. The bacteria are allowed to produce the amino acids until the manufacturer decides a sufficient quantity is present. The amino acids are then separated and dried. One of the amino acids, phenylalanine, is then reacted with methanol to produce and ester. The other amino acid, aspartic acid, is then modified proprietary step so it only reacts in the intended manner. The modified acids are then combined at elevated temperatures so they can react.
After cooling and adding a solvent, the products of the reaction crystallize. This compound is further reacted with acetic acid. Chemical additives are nothing new, of course — most processed foods contain more than one artificial flavoring, emulsifier, coloring, or gelling agent — and sugar substitutes are among the most-studied additives in the world.
Yet rumors of their side effects persist, and their escalating potency demands attention. Walters himself has studied artificial sweeteners for nearly 25 years, so he's well aware of the central irony of his field: The most successful sugar substitutes have all been discovered by accident. Saccharin was invented in Baltimore about years ago by two chemists at Johns Hopkins University who were experimenting with coal-tar derivatives.
Aspartame was found in the s by a medical chemist in Illinois who was investigating a drug for gastric ulcers. Sucralose was discovered in by a graduate student at King's College London. His head researcher had told him to test some compounds, but he misunderstood and tasted them instead. Of the three sweeteners, sucralose has been touted as the most natural, but that claim "has more to do with clever marketing than with chemistry," Walters says. Although sucralose is made from sugar, its chemical structure is significantly different: A molecule of the artificial sweetener has three chlorine atoms, whereas sugar has three pairs of oxygen and hydrogen atoms.
By contrast, the only unnatural component in aspartame is a methyl ester bond that connects phenylalanine and aspartic acid, two amino acids abundant in the human body. The body's digestive enzymes recognize aspartame as a protein and break it down much as they would a natural compound. Sucralose, on the other hand, slips through undigested, as does saccharin — a compound of carbon, nitrogen, oxygen, and sulfur atoms. How can such different structures all taste sweet?
Until very recently, the answer was anyone's guess. Thousands of sweet-tasting compounds belonging to more than chemical classes have been discovered, including low-molecular-weight carbohydrates, aminoacyl sugars, amino acids, peptides, proteins, terpenoids, chlorinated hydrocarbons, halogenated sugars, N-sulfonyl amides, sulfamates, polyketides, anilines, and ureas.
Scientists have long known that our taste buds contain receptors that react to all these compounds, but no one knew exactly how they worked. Then four years ago Charles Zuker, a rather aptly named neuroscientist at Howard Hughes Medical Institute, made a startling announcement: All the sweet things in life are perceived by a single receptor.
