Analysis of the hydrolysis of inulin using real time H-1 NMR spectroscopy

Barclay, Thomas; Ginic-Markovic, Milena; Johnston, Martin R; Cooper, Peter; Petrosky, Nikolai


The hydrolysis of various carbohydrates was investigated under acidic conditions in real time by1H NMR spectroscopy, with a focus on the polysaccharide inulin. Sucrose was used as a model compound to illustrate the applicability of this technique. The hydrolysis of sucrose was shown to follow pseudo first order kinetics and have an activation energy of 107.0 kJ mol-1 (SD 1.7 kJ mol-1). Inulin, pullulan and glycogen also all followed pseudo first order kinetics, but had an initiation phase at...[Show more]
