General description

Acetoacetamide is a degradation product of acesulfame-K, sweetener. Acetoacetamide undergoes alkaline hydrolysis to form salt of acetoacetic acid.

Application

Acetoacetamide was used in a study to assess the stability of artificial sweeteners- aspartame, acesulfame-K and binary sweetener blend of aspartame x acesulfame-K during storage. Acetoacetamide was also used in analysis of multiple sweeteners and their degradation products in lassi by HPLC.

A solid phase extraction method using C18 cartridges was standardized for the isolation of multiple sweeteners (aspartame, acesulfame-K and saccharin) and their degradation products (diketopiperazine, Lphenylalanine, acetoacetamide and 2-sulfobenzoic acid) from lassi. Analytical conditions for HPLC were standardized over C18
