Acesulfame potassium, also known by ace K, acesulfame K, is an artificial sweetener used in foods. It is almost 200 times sweeter than sugar and is also found not to change blood insulin levels. Thus, it is commonly called as diabetic sweetener.
Acesulfame K is usually mixed with other artificial sweeteners. The other two sweeteners masks the bitterness of acesulfame lave in our mouth. In its solid form, acesulfame-K is highly stable at room temperature, even in the presence of light. When in solution, its stability is dependent on pH and temperature. Glycaemic index of acesulfame potassium is zero and it is one of the cheapest sweeteners.
In the first step, Sulphamic acid and amine are made to react to produce amido sulphamic acid salt. Simultaneously, acetic acid and amine react to give triethylammonium acetate. In the second step, the amido sulphamic acid salt reacts with diketene and gives acetoacetamide salt. This reaction takes place between -30 to 50 °C and for 0.5 to 12 hours. The final step is cyclization, where acetoacetamide salt is subjected to -70 to 175 °C and between 0.01 to 10 MPa, is hydrolysed , neutralised and fi2022-08-24 03:16:23y purified to give Acesulfame K.
Used in jellies, jams, chocolates, beverages etc. Acts as a sweetener in foods and beverages. Even a little amount of acesulfame is very sweet and thus considered economical.
