aspartame is a high-intensity sweetener that is a dipeptide, provid- ing 4 cal/g. it is synthesized by combining the methyl ester of phenylalanine with aspartic acid, forming the compound n-l-alpha- aspartyl-l-phenylalanine-1-methyl ester. it is approximately 200 times as sweet as sucrose and tastes similar to sugar. it is compara- tively sweeter at low usage levels and at room temperature. its mini- mum solubility is at ph 5.2, its isoelectric point. its maximum solubility is at ph 2.2. it has a solubility of 1% in water at 25°c. the solubility increases with temperature. aspartame has a certain insta- bility in liquid systems which results in a decrease in sweetness. it decomposes to aspartylphenylalanine or to diketropiperazine (dkp) and neither of these forms is sweet. the stability of aspartame is a function of time, temperature, ph, and water activity. maximum stability is at approximately ph 4.3. it is not usually used in baked goods because it breaks down at the high baking temperatures. it contains phenylalanine, which restricts its use for those afflicted with phenylketonuria, the inability to metabolize phenylalanine. uses include cold breakfast cereals, desserts, topping mixes, chew- ing gum, beverages, and frozen desserts. the usage level ranges from 0.01 to 0.02%.
