The complete chemical name of Neotame™ is N-[N-(3,3-dimethylbutyl)-L-aspartyl] -L-phenylalanine-1-methyl ester. It is a white crystalline powder with the chemical formula C20H30N2O5 and melting point of 80.9-83.4 °C.
The solubility of Neotame is 12.6 g / l at 25 °C. Its complete solubility is very important for normal production. It is 8,000-10,000 times sweeter than sugar. The sweetness of 5% solutions is in the range of 8,000 times that of sugar; the sweetness of 2% solutions is rated at 10,000 times the sweetness of sugar. According to the statement No. 4 as of 2003 by Ministry of Health of the People's Republic of China, Neotame can be used in all types of food products.
The approximate dosage is the following: 8-17 mg / l for drinks, 10-35 mg / kg for other food products. Dry powder of Neotame retains its properties for a long time (5 years) under normal storage conditions (room temperature, humidity of 70% and closed packaging). However, the stability of aqueous solutions of Neotame is influenced by many factors, such as temperature, pH, time.The sweetness rate of an aqueous solution of Neotame can decrease at room temperature of 25 °C depending on pH value:
The optimum pH value is 4.5
The stability of the Neotame solution increases if it is used together with sugar or other sweeteners.
