Sweetener (intense Sweetener). Its sweetness is very high, usually it is 50 times higher than that of sucrose. According to different sources, there is a natural extract, natural product chemistry modified semisynthetic products and pure chemical synthesis products. A large supply of natural extracts is the main Stevia extract and long winded Sweet and natural product chemistry modified products such as aspartame, neotame and sucralose, pure synthetic chemical products such as saccharin, cyclamate and acesulfame.
Sweetener can be used for low calorie baked food sweetener, but must have a good thermal stability. Aspartame has been approved for use in food, but due to its poor thermal stability and is not suitable for baking food. American newt company newest development of neotame is aspartame derivative, its thermal stability and sweetness have greatly improved and sweet pure than aspartame, sweet good distribution is used for baking food, which has great potential for development of the sweetener.
Neotame is aspartate dipeptide derivatives, is a new product developed at a cost of $80 million by American newt company after aspartame, representing the latest achievements of sweetener research field. It is according to the human sweet receptor double hydrophobic binding hypothesis. In aspartame molecule with a hydrophobic groups and the formation of aspartame derivatives. It can also act on the human sweet receptor of two hydrophobic binding sites and therefore sweetness increased greatly, 6000 to 10000 times sweeter than sucrose, 30 to 60 times than Biasiba sweet.

Neotame is a high intensity sweetener and flavor enhancer for use in foods, except in meat and poultry. it is 7,000–13,000 times sweeter than sugar and has a clean, sweet taste. it is a derivative of the dipep- tide composed of amino acids, aspartic acid, and phenylalanine. it can be blended with nutritive sweeteners such as sucrose and high fructose corn syrup as well as with high intensity sweeteners such as aspartame and sucralose. uses include beverages, baked goods, desserts, cereals. it functions as a flavor enhancer in certain applica- tions and flavor systems, such as mint-flavored chewing gum.
