Discovery and Features
Cyclamate, a nonnutritive sweetener, is an artificial substance derived from cyclamic acid (also known as cyclohexylsulfamic acid). It is commonly found in the form of sodium or calcium salts, which are stable to heat and highly soluble in water. This white crystalline powder is approximately 30 times sweeter than ordinary table sugar and is used as a noncaloric sweetener in various food products and beverages.
The discovery of cyclamate dates back to 1937 when chemist Michael Sveda accidentally stumbled upon it at the University of Illinois. He had been working on the synthesis of an antifever drug, and during a cigarette break, he found his cigarette tasted unusually sweet due to the cyclamate residue on his fingers. Recognizing the potential of the substance, Sveda filed for a patent in 1939, which was eventually granted in 1940.
In addition to its sweetness, cyclamate has other advantageous properties that make it a popular choice for food and beverage industries:
- Odorless: Cyclamate does not have any discernable smell, making it an ideal ingredient in various applications without altering the overall aroma of a product.
- Heat stable: As a heat-stable substance, cyclamate can be used in cooking and baking processes without degrading or losing its sweetening properties.
- Water solubility: Due to its high water solubility, cyclamate easily dissolves and mixes with other ingredients in food and beverages, providing an even distribution of sweetness.
- Cost-effective: Cyclamate is relatively inexpensive compared to other sweeteners, which makes it an attractive option for manufacturers.
While cyclamate is approved for use in more than 50 countries, it has been banned in the United States since 1970 due to concerns over its safety.
Types and Properties
Cyclamate is an artificial sweetener that comes in two common forms: sodium cyclamate and calcium cyclamate. Both of these compounds are odourless white crystalline powders and are derived from salts of cyclohexylsulfamic acid (C6H11NHSO3H). The primary difference between the two lies in their sodium and calcium content, with sodium cyclamate being the more frequently used form.
Sodium cyclamate (C6H12NNaO3S) is the most popular form of cyclamate due to its sweet taste and its ability to effectively sweeten food and beverages. Calcium cyclamate, on the other hand, may be used as a replacement in low-sodium or sodium-free products; however, it is not as widely used because it can cause gelation and precipitation in some applications.
Cyclamate possesses a sweetness level that can be up to 50 times greater than sugar, depending on the type of application. Interestingly, when cyclamate is combined with saccharin, the two substances exhibit synergistic sweetening properties, offering an even sweeter taste and improved flavor.
The pH level of cyclamate solutions tends to be relatively neutral, although it may be slightly acidic or alkaline in certain applications. Both sodium and calcium cyclamate exhibit stability, primarily due to their crystalline structure and ability to resist degradation. They are also stable under a wide range of temperatures and pH values, making them well-suited for use in various food and beverage products.
In summary, cyclamate is a versatile artificial sweetener available in two forms: sodium cyclamate and calcium cyclamate. Both are stable and offer a sweet taste with varying levels of sweetness, depending on the application. The properties of cyclamate make it a popular choice for use in food and beverage products.
