Abstract
A method for separating bran, endosperm and germ in a seed particle, comprising: Smashing the seed against a surface that produces separation of the germ from a bran-endosperm complex; Separating the germ from the bran endosperm complex; Freezing the bran endosperm complex; and Subjecting the frozen bran endosperm complex to a force wherein the bran is separated from the endosperm intact and the endosperm is fractionated into smaller pieces.

A method for separating bran, endosperm and germ in a seed particle, comprising:
- Smashing the seed against a surface that produces separation of the germ from a bran-endosperm complex;
- Separating the germ from the bran endosperm complex;
- Freezing the bran endosperm complex;
- and Subjecting the frozen bran endosperm complex to a force wherein the bran is separated from the endosperm intact and the endosperm is fractionated into smaller pieces.
A bran particle characterized by having a symmetry substantially unchanged from its native symmetry.
A system for separating bran, endosperm and germ from a seed, comprising:
- A unit having a surface that produces separation of germ from bran endosperm complex in a seed, without evolution of heat and without use of water.
A method for retaining oil in germ and other fractions of an oil bearing seed, without damaging pericarp and starch, following fractionation of the oil bearing seed, the method comprising:
- optionally pretreating the oil bearing seed;
- and adding the oil-bearing seed with the germ fraction to an hypertonic solution, the hypertonic solution having an ionic strength effective for retaining oil in the germ and other fractions of the oil bearing seed.
A germ separated from an oil-bearing seed, the germ retaining substantially all of the oil held by the germ when it was part of the oil bearing seed.
A system, comprising:
- an impact mill;
- a vessel and an hypertonic solution contained in the vessel;
- and a cryogenic tank.
A system, comprising:
- a dry mill;
- a vessel and an hypertonic solution contained in the vessel.
