An innovative refining process of canola seed: Highly efficient, economical, high-quality products

11 partners are developing a new extraction process of canola seed with alcohol in the so-called "EthaNa" project

In the recently initiated Research Cooperation Project "EthaNa", scientists from the Fraunhofer Center for Chemical Biotechnological Processes (CBP) and ten other partners are researching a novel concept for the refining of canola. They develop the methodologies and afterwards test it in a pilot plant. EthaNa stands for ethanolic native extraction of peeled rape seed, on which the process concept is based. The alternative treatment line is intended to be integrated into conventional oil mills. With a time period until mid-2020, the scientists aiming  to evaluate the technical, economic and ecological parameters on a pilot scale in this research project.

Compared to extraction processes with the solvent hexane, which were customary up to now, the EthaNa-refining processes might enable a significant qualitative improvement of the products rape oil and rape kernel concentrate. In addition, new highly valuable substances which have not yet been derived from rape seed are isolated. This will open up further sales markets in future and increase overall sales revenues from the oleaginous seed.
The EthaNa concept is a fully integrated process for rape seed refining. It includes the dehulling of rape seed, the cell disruption of the rape kernels as well as the fractionated extraction with ethanol without pressing of the seed. The process conditions at a maximum temperature of 80°C is very gentle as well. Direct extraction with alcohol makes it possible to obtain high-quality plant-oil and proteins as primary products. Secondary plant ingredients such as sinapic acid, tocopherols, phytic acid or glucosinolates will be isolated, which can be further used for technical or cosmetical products. In future, the process could also be integrated into a plant-oil biorefinery.

The project is funded by the German Federal Ministry of Food and Agriculture (BMEL) via the project management agency Fachagentur Nachwachsende Rohstoffe e. V. (FNR). Further information is available on fnr.de under the following promotion number:
