Malte Kaspereit co-authored a paper with Hoang Nguyen (now at Northumbria University, Newcastle/UK) and Tuomo Sainio (LUT – Lappeenranta-Lahti University of Technology, Finland) that covers an experimental-theoretical study on the production of oligosaccharides from natural sources. It is shown that high-quality oligosaccarides – which are promising as healthy food ingredients – can be obtained with defined molar weight distribution by recycle-integrating an acidic hydrolysis reaction with a separation by size exclusion chromatography. The paper stems from the collaboration of Malte Kaspereit with Tuomo Sainio on the design of reactor-separator-recycle processes. Part of the work was performed by Hoang Nguyen during a three-month research visit in the Advanced Separation Processes group at TVT.

The work was supported by the Collaborative Research Centre CRC 1411 “Design of Particulate Products”.
