| Abstract | ||
| This study assessed the effect of asesulfame K on the stability of aspartame in diet cola. Since acesulfame K is resistant to high temperatures, the effect of a blend of two sweeteners on its thermal resistance in diet cola was also studied. A cola containing two sweeteners (1:1 weight ratio) was prepared and, after quality control testing, was stored at temperatures of 4, 25 and 40 °C for 6 months. The concentration of aspartame remaining was measured every 15 days using high performance liquid chromatography. Statistical results showed better stability of aspartame in cola containing acesulfame K. The kinetic equations of aspartame decomposition represented a first order reaction; aspartame half-life results also confirmed this result. The amount of activation energy was greater in cola without acesulfame K and indicated the greater effect of temperature on aspartame decomposition in this sample. | ||
