Neotame is synthetic, high-strength sweetener appearing a white or off-white powder. Its chemical formula is N-[N-(3,3-dimethylbutyl)-l-α-Apartyl]-l-phenylalanine 1-methyl ester, which is a dipeptide methyl ester used as a sweetener and flavor enhancer in the food field.
Neotame is an improved product of aspartame, which uses aspartame and 3,3-dimethylbutyraldehyde (DMBA) as raw materials for catalytic hydroreduction, in which the catalytic reducing agent mainly uses palladium(PD), platinum(PT) and other metal catalysts, and the most commonly used is palladium-carbon catalyst, which is the most commonly used preparation method. Of course, the raw materials can be replaced with halogenated substances. It then goes through post-processing processes such as purification, drying, and milling. In this chemical reaction alone, without exaggeration, Neotame is 30-60 times sweeter than aspartame and 7,000-13,000 times higher than sucrose. It is worth mentioning that there will be a critical value in the sweetness application of neotame, and too much addition will lead to a regression in sweetness. Because the sweetness produced by the chemical bonds of Neotame has an amplifying effect, resulting in a high degree of sweetness, if the content of Neotame is relatively high, then the chemical bonds that produce sweetness will be close to each other, and their sweetness enhancing regions will overlap, which will affect the overall sweetness level. As a result, low concentrations of Neotame will result in extremely high levels of sweetness, dosage savings and low economic costs. For this feature, it will be more flexible in its use. For example, if you accidentally add too much sweetness and cause it to be too sweet, it can still bring him back to the desired level of sweetness. Neotame is widely used in the food field after being compounded with other sweeteners due to its flavor-improving properties. Recent technological advances have shown that the reaction conditions for enzymatic hydrolysis of neotame without catalysts are more gentle.
