Abstract
The present invention relates to a process for purifying starches. More particularly, the invention relates to a method of removing off-flavors, off-odors, and off-colors from starches by extraction of the components causing the off-flavors, off-odors, and off-colors with a fluid in the supercritical or liquid phase.
Claims23
A process for extracting components from starch comprising:
- (i) contacting the starch with a supercritical fluid or liquid phase fluid for a sufficient length of time and at a sufficient temperature and pressure effective to dissolve the components in the supercritical fluid or liquid phase fluid without substantially changing the physical structure of the starch;
- and
- (ii) removing the supercritical fluid or liquid phase fluid containing the dissolved components.
A purified starch produced according to the process of comprising:
- (i) contacting the starch with a supercritical fluid or liquid phase fluid for a sufficient length of time and at a sufficient temperature and pressure effective to dissolve the components in the supercritical fluid or liquid phase fluid without substantially changing the physical structure of the starch;
- and
- (ii) removing the supercritical fluid or liquid phase fluid containing the dissolved components.
