Abstract
The invention relates to the separation and of components from vegetable raw materials. The invention provides a method for separating components from vegetable material which has at least leaf and/or stem parts, characterized in that the material is at least partly fiberized and subsequently is separated into a fiber fraction and a juice stream, such that the fiber fraction principally has relatively firm tissues such as epidermis, sclerenchyma and vascular bundles, and the juice stream principally contains soft tissues such as parenchyma and cytosol. In preferred embodiment, the invention provides a method for separating a juice stream which has in particular chloroplasts.
Claims25
A method for separating virtually completely cytosolic and parenchyma components from relatively firm tissues (vascular bundles, sclerenchyma, epidermis) of vegetable material having at least leaf and/or stem parts comprising:
- a) at least partially fiberizing said vegetable material by means of a refiner to dissociate virtually completely all cytosolic and parenchyma materials from relatively firm tissues and
- b) subsequently separating said at least partially fiberized material into
- i) a fiber fraction comprising relatively firm tissues, and
- ii) a juice stream comprising soft tissues.
A fiber fraction obtained by a method for separating virtually completely cytosolic and parenchyma components from relatively firm tissues (vascular bundles, sclerenchyma, epidermis) of vegetable material having at least leaf and/or stem parts comprising:
- a) at least partially fiberizing said vegetable material by means of a refiner to dissociate virtually completely all cytosolic and parenchyma materials from relatively firm tissues and
- b) subsequently separating said at least partially fiberized material into
- i) a fiber fraction comprising relatively firm tissues, and
- ii) a juice stream comprising soft tissues.
A biodegradable product comprising a fiber fraction obtained by a method for separating virtually completely cytosolic and parenchyma components from relatively firm tissues (vascular bundles, sclerenchyma, epidermis) of vegetable material having at least leaf and/or stem parts comprising:
- a) at least partially fiberizing said vegetable material by means of a refiner to dissociate virtually completely all cytosolic and parenchyma materials from relatively firm tissues and
- b) subsequently separating said at least partially fiberized material into
- i) a fiber fraction comprising relatively firm tissues, and
- ii) a juice stream comprising soft tissues.
A juice stream obtained by a method for separating virtually completely ctosolic and parenchyma components from relatively firm tissues (vascular bundles, sclerenchyma, epidermis) of vegetable material having at least leaf and/or stem parts comprising:
- a) at least partially fiberizing said vegetable material by means of a refiner to dissociate virtually completely all cytosolic and parenchyma materials from relatively firm tissues and
- b) subsequently separating said at least partially fiberized material into
- i) a fiber fraction comprising relatively firm tissues, and
- ii) a juice stream comprising soft tissues.
A protein enriched product comprising a juice stream obtained by a method for separating virtually completely cytosolic and parenchyma components from relatively firm tissues (vascular bundles, sclerenchyma, epidermis) of vegetable material having at least leaf and/or stem parts comprising:
- a) at least partially fiberizing said vegetable material by means of a refiner to dissociate virtually completely all cytosolic and parenchyma materials from relatively firm tissues and
- b) subsequently separating said at least partially fiberized material into
- i) a fiber fraction comprising relatively firm tissues, and
- ii) a juice stream comprising soft tissues.
An apparatus for separating virtually completely cytosolic and parenchyma components from relatively firm tissues (vascular bundles, sclerenchyma, epidermis) of vegetable material having at least leaf and/or stem parts comprising:
- a) a refiner which dissociate virtually completely all cytosolic and parenchyma materials form said relatively firm tissues, and
- b) a separator which separates the fiber fraction from the juice stream.
