It can be absorbed by human body completely and is harmless and quite safe to use. It tastes pure, cool and refreshing, similar to sucrose Item Standards Results Name Aspartame Aspartame Cas No 22839-47-0 22839-47-0 Chemical formula C14H18N2O5 C14H18N2O5 Appearance white crystalline powder Molecular weight 294.31 294.31 Purity w%≥ 98.0~101.0 98.50 Loss on drying w%≤ 4.5 3.98 PH value (100g/L) 4.5~6.0 5.00 Transparency(100g/L) w%≥ 95.0 98.60 Diketopiperazine(5-Benzy-3,6-Dioxo-2-PiperazineaceticAcid) w%≤ 1.0 0.03 Heavy Metals Pb ≤1ppm ≤1ppm Characteristics 1. Aspartame, an artificial sweetener, is approximately 200 times sweeter than sucrose, or table sugar. 2. The sweetness of aspartame lasts longer than sucrose, so it is often blended with other artificial sweeteners such as acesulfame potassium to produce an overall taste more like sugar. 3. Aspartame may hydrolyze (break down) into its constituent amino acids under conditions of elevated temperature or high pH. This makes aspartame undesirable as a baking sweetener 4. The stability when dissolved in water depends markedly on pH. At room temperature, it is most stable at pH 4.3 5. However, because its breakdown products include phenylalanine, aspartame must be avoided by people with the genetic condition phenylketonuria (PKU). Usage Aspartame is being used in a wide variety of foods, beverages, and pharmaceuticals in over 120 countries.
