Carbotrace 540 helps to determine purity of plant raw materials

Researchers from the Royal Institute of Technology and Karolinska Institutet in Sweden reported about an environmentally friendly process to obtain pure cellulose nanofibrils from the green macroalgae ulva lactuca (Wahlström et al. (2020) Cellulose 27, 3707–3725). Analysis of the monosugars revealed that the extracted cellulose contains mainly glucose, but also a fraction of xylose. Carbotrace 540 allowed the researchers to analyze the carbohydrates in its polymeric state and was key to uncover that the macroalgae contain a mixture between highly pure and a xylose-glucose polysaccharide, such as xyloglucan.
