Evaluation of non-food utilization of by-products of the oil extraction of rapeseed

The processing of rapeseed leads to the procucts "oil" and "defatted rapeseed meal". Expecting growing markets for the rapeseed oil in non-food industry the surphases of rapeseed meal cannot be absorbed in the traditional animal feed markets. Therefore new outlets for the rapeseed meal have to be created. In the study several utilization strategies have been evaluated, favorizing the isolation of proteins that are characterized by good sales properties. High value-added applications as bioplastics, glues or binders do require protein isolates in sufficient functionality. Main application areas are characterized with respect to market volumes and requirements.
