To tackle the issue of non-sugar compounds reduction in sugar beet molasses towards improved sugar recovery and complete molasses valorisation, various treatments were developed. As a step forward to sustainability, this study explores the applicability of alkaline hydrogen peroxide treated sugar beet pulp (AHPSBP) and commercial cellulose-based adsorbents for molasses purification by monitoring the changes in molasses colour, turbidity and sucrose content. Treatment conditions defined by Box-Behnken design were pH (3-7), molasses dry substance (30-50 degrees Brix), and adsorbent concentration (9-21 g/L) with constant treatment temperature. Favourable con-ditions for molasses colour reduction were acidic and neutral environment for commercial adsorbents (4.9-27.1%) and AHPSBP (20.3-32.7%), respectively. Turbidity reduction was higher than 90% in neutral environment regardless of applied adsorbent with minimal detected sucrose content reduction. AHPSBP exhibited greater potential regarding molasses colour and turbidity reduction compared to commercial adsor-bents obtained at favourable pH with lower applied concentrations.
