The project ran between September 2017 and August 2020.
The project, that was a part of the innovation project BioEconomy 2.0 – Improved valorisation of residue streams, has focused on processing of two industrial side streams: oat hulls and potato fiber. Most of the practical work has been carried out at the Department of Biotechnology, Lund University and the industrial partners have carried out certain process steps. Nouryon has performed successful work on chemical bleaching of oat hulls. Lantmännen Ek. För. has carried out grinding of oat hulls and evaluation of oat hull‐based products. Lyckeby Starch has worked with various process alternatives to improve the properties of potato fiber. ImmuneBiotech Medical Sweden has developed potentially health‐promoting lactic acid bacteria grown on oat hull‐based substrates.
Both side streams have been shown to be rich in dietary fiber and two product prototypes have been developed based on oat hulls. These can be expected to have positive health effects. One consists of bleached, mainly insoluble dietary fiber and the other of soluble dietary fiber. High yields have been obtained in both processes. Application tests remain to be done. A follow‐up project is ongoing.
