What is Aspartame?
Molecular Formula (Aspartame): C14H18N2O5
Molecular Weight: 294.30 g/mol
Chemical Name: Aspartame
CAS Number: 22839-47-0
This chemical substance is a chemical compound in the artificial sweetener group, developed in 1965 by a chemist during research for use in the treatment of ulcers.
Chemically, it is a substance that is the methyl ester of Aspartic Acid and phenylalanine.
E Code = E591.
Other Names are as Follows;
- Asp-Phe Methyl Ester
- Methyl Aspartylphenylalanate
- Dipeptide Sweetener
- Aspartic Acid Phenylalanine Methyl Ester
- L-Aspartyl-L-Phenylalanine Methyl Ester
How is Aspartame Produced?
The initial reaction of aspartame production begins with L-Aspartic Acid, L-Phenylalanine, or L-Phenylalanine Methyl ester. To obtain a sweet form, the L-Configuration process of the amino acids must take place.
Peptide production methods continue in the later stages of production. In these production methods, there may be a requirement for a protective agent for Aspartic Acid. In large-scale productions, formylaspartic acid anhydride can be used as a protective agent.
What are the Physical and Chemical Properties?
In terms of physical appearance, it is in crystalline powder form. In terms of taste, it is approximately 200 times sweeter than the Sucrose compound.
It is odorless.
In the presence of moisture, it hydrolyzes by decomposing into the aspartylphenylalanine compound and other chemical compounds. This hydrolysis event leads to a reduction in the sweetness of aspartame.
Melting Point is 346.5 °C.
Density: 1.35 g/cm³
Boiling Point: Information not available.
Solubility varies according to temperature, pH, and the presence of water. It has the highest solubility in low pH environments and at a temperature of 25 °C. For example, if the pH is around 2 and the temperature is 25 °C, it has been determined to be 20 mg/ml water.
In terms of stability, it has stable characteristics in the absence of moisture. However, it experiences loss of taste in the presence of moisture.
What are the Usage Areas of Aspartame?
- It is used as an artificial sweetener in carbonated beverages in some countries.
- Due to its high sweetness property, it is used as a sweetener in chewing gum production.
- It is used to provide sweetness in tea, coffee, and some breakfast items.
- It is used in the manufacture of low-calorie foods and beverages. In this application, it is used either alone or mixed with another sweetener.
- Used as a sweetener in ice cream manufacture.
- Used as a sweetener in cough syrups in the field of pharmacology.
- Used in chewable tablets and sugar-free liquid formulations.
- Used in gelatin production to provide a sweet taste.
- Used in the production of Gastroesophageal Reflux Medications.
What are the Factors Affecting Prices?
The price of aspartame is directly dependent on the prices of Aspartic Acid and Phenylalanine. This is because these raw materials are used in its production. As the prices of these raw materials increase, the price of this artificial sweetener will increase.
Aspartame prices have continuously increased since it began to be used commercially. This is because its areas of use have increased every year. For this reason, since the amount of raw material produced cannot meet the demand adequately, its prices have risen.
Companies that sell aspartame are generally the ones that determine this pricing policy.
