Crystallography
The crystal structure of the aspartame anhydrate is in the monoclinic system with space group P21 and cell parameters: a=19.4103(11) Å, b=4.9608(3) Å, c=15.6565(9) Å, β=94.875(2)°, V=1502.14(15) Å3.
Applications
Aspartame is known as a low-calorie artificial sweetener that is much sweeter than sugar and is widely used in the food and pharmaceutical industries due to its desirable properties. That is a dipeptide gained by condensation of the alpha-carboxy group of L-aspartic acid with the amino group of methyl L-phenylalaninate.
Aspartame is found in diet drinks, syrup powders, chewing gum, jellies and puddings, breakfast cereals, dairy products and mixed desserts and also is very stable in acidic products, but when food is heated it decomposes and loses its sweet taste. Therefore, aspartame is mainly used in diet drinks and other foods that are consumed cold.
Aspartame in high temperatures is lost its sweetness so it isn’t use for foods that needs heating long time. and also for increase palatability of some medicines and vitamins it was use.
Safety information
The concern with humans that FDA mention is that aspartame converted to methanol during processing in the body, which is extremely toxic. However, small amounts of this substance can also combine with free methanol due to increased absorption and cause side effects. Free methanol is existence in some foods and is produced when aspartame is heated. It is then converted to formaldehyde, a neurotoxin and carcinogen.
