Abstract: The present invention relates to a process for preparation of protein-enriched products, such as plant protein isolates or protein-fibre formulations, from plant materials such as oilseeds, as well as to the uses of the products obtainable via said process in human food and/or animal feed. In particular, the presented herein processes advantageously make use of solvents based on low-boiling azeotropic mixtures made of an apolar and lipophilic organic ester having up to 5 carbon atoms, with an alcohol having up to 5 carbon atoms, which solvents not only make the need to use noxious hexane-based solvents obsolete, but also can undergo reutilisation cycles by being easily obtainable and recoverable from spent solvents and/or mother liquors as used in the presented herein processes, and consequently render the disclosed processes extremely energy-efficient, suitable for large-scale industrial production, as well as eco-friendly.

Abstract: The present invention concerns a process wherein native and functional protein isolates can be successfully obtained from plant material such as oilseeds, legumes and lentils. This can be achieved by a proper pre-treatment of the plant material, followed by a method of extracting proteins under mild and non-destructive conditions using an aqueous solvent, followed by fractionation, concentration and further purification using a novel combination of GRAS organic solvents.

Abstract: The present invention relates to a process of extracting native proteins from vegetable source materials such as oil-seeds, legumes and grains. Native proteins mentioned in this invention are present in the source material in their non-denatured state, i.e. with their functional properties relevant to application in food industry like solubility preserved and not compromised by processing conditions. Source materials mentioned in the present invention are of vegetable origin and typically contain significant (>5% by weight) amounts of native oils and lipids. The invention further relates to a device for carrying out this process and to the native protein obtainable by the process of the invention.
