The high molecular weight alkaline degradation products of sucrose (HMWADPS) are the colored substances in sugar juice. Few studies have been conducted to elucidate the structure of HMWADPS. In the present study, the structure of HMWADPS was analyzed by nuclear magnetic resonance and Fourier transform infrared spectroscopy, and the molecular weight of HMWADPS was determined by gel permeation chromatography. The chemical structure of HMWADPS consisted of carbonyl carbon (ketones, aldehyde, and carboxyl), conjugated double bonds, alcoholic hydroxyl, and saturated alkanes. The molecular weight of HMWADPS was calculated to be predominately composed by 19525 and 2357 Da, respectively.
