Characterisation of dissolved organic matters in molasses by using LC-OCD-OND [Full subscriber]

Abstract Molasses is widely used in many fermentation processes. As wastewater from molasses fermentation can pose an environmental problem, scientific characterisation of the non-sugar components of molasses is worthwhile. Whilst most previous work has focused on the nutrient content and chemical composition of molasses, the present study investigates molasses fractionation based on molecular weight distribution. In this study, Size Exclusion Liquid Chromatography Organic Carbon Detection (LC-OCD) was utilised to characterise the dissolved organics in six molasses samples. Through this method, the dissolved organic matter of each sample was fractionated into six groups, which could then be quantified. LC-OCD results suggest…
