Acesulfame-K (or potassium acesulfame) is approximately 200 times sweeter than sugar (sucrose) and has no calories. It is an organic salt that was discovered in Germany in 1967. By now acesulfame-K is used in more than 100 countries throughout the world e.g., in the USA, Japan, Switzerland, Norway, Canada and Australia. Acesulfame-K is not converted or stored in the body. It dissolves well in water, it is absorbed quickly and leaves the body unaltered.
Aspartame is approximately 200 times sweeter than sugar (sucrose) and contains 4 kcal per gram. Since you need so little aspartame to sweeten a product, the quantity of energy from aspartame in products is negligent. A pinch of aspartame that has 0.1 kcal supplies the same sweetness as one teaspoon of sugar (16 kcal).
Cyclamate is 30 to 50 times sweeter than sugar (sucrose) and contains no calories. It was discovered as a sweetener in 1937 in the USA and by now it has been approved in more than 50 countries. It is a calcium salt that comes from cyclamic acid. Cyclamate is only slightly absorbed in the body and leaves the body unaltered via the kidneys. Most of it leaves the body unaltered with defecation.
Neohesperidin DC (E959)
Neohesperidin DC is approximately 400 to 600 times sweeter that regular sugar (sucrose). It provides 2 kcal/gram of energy, but since so little is needed, this is negligent.
Neotame is approximately 800 times sweeter that regular sugar (sucrose) and therefore a minimum quantity is needed for sweetening a product. Neotame does not have any calories. It is made up of amino acids, the building materials of albumen. These amino acids are also found in all sorts of other foods, such as vegetables, dairy products and meat. It is created from a reaction between aspartame and 3.3-dimethulbutyraldehyde. Neotame is absorbed in the body, but leaves it unaltered via urine and faeces, therefore supplying no calories.
Saccharin is 300 to 500 times sweeter than regular sugar (sucrose) and has no calories. It was discovered 1879 by employees of John Hopkins University in the United States. Saccharin is not converted (metabolised) by the body and is totally released via the kidneys.
Steviol glycoside (or stevioside or rebausioside) is approximately 200 to 300 times sweeter than regular sugar (sucrose) and has no calories. In South America is has been used for ages as a sweetener, extracted from the leaf of the stevia plant. Steviol glycoside, better known under the name ‘stevia’ is extracted from the stevia plant (Stevia Rebaudiana). The plant leaves are processed in hot water. The liquid solution is purified further and dried until the steviol glycoside crystals remain. In the border areas between Paraguay and Brazil, the place where the plant originates, stevia has been used for ages as a sweetener.
Sucralose is approximately 600 times sweeter than regular sugar (sucrose) and has no calories. Sucralose was discovered in 1976 by researchers at a London university who worked for a British sugar manufacturer. By now, sucralose has been approved in more than 50 counties, including Canada, Australia, Japan, China and Russia.
