Abstract
Whole corn kernels or particles thereof are enzymatically disassembled. The method can produce a solid starch fraction, a solid pericarp fraction, and a liquid fraction. A high purity starch solids product can be provided suitable for use as a feedstock in other chemical processes.
Claims34
A method for processing a corn product, comprising:
- enzymatically digesting whole corn kernels or corn kernel particles in a liquid digestion medium comprising enzymes including a protease and a cellulase, to thereby separate components of the whole corn kernels or corn kernel particles by action of the digestion medium and form, by action of the digestion medium, a solid corn starch fraction including released corn starch granules, a solid pericarp fraction, and a liquid fraction containing dissolved glucose;
- and
- separating the solid corn starch fraction from the solid pericarp fraction and from the liquid fraction so as to provide a separated solid corn starch fraction.
A method for deconstruction of corn kernels, comprising:
- an enzyme deconstruction of corn kernels in an aqueous medium containing enzymes, the deconstruction occurring by action of the aqueous medium containing enzymes on the corn kernels, so as to form, by action of the aqueous medium containing enzymes on the corn kernels, a solid starch precipitate including released corn starch granules.
