Abstract
Disclosed is a method for improving the yield of sprayed corn bran in a corn wet-milling process, an enzyme preparation is added in the process of separating fiber from starch and protein, the fiber residue after the enzyme preparation treatment contains less water, less starch and/or protein residue, and has a looser and more fluffy structure, the yield of the sprayed corn bran in the corn wet-milling process can be remarkably improved while ensuring normal color of the finished sprayed corn bran, that is, the amount of concentrated corn soaking solution sprayed on the fiber corn bran is significantly increased.
Claims19
A method for increasing the yield of sprayed corn bran in a corn wet milling process, the method comprising the following steps:
- a) impregnating corn kernels with a solution containing sulfurous acid, and collecting a corn impregnation liquid for concentration;
- b) grinding the impregnated corn kernels to separate fibers from starch and proteins in the corn kernels, and collecting a fiber residue;
- and
- c) mixing the concentrated corn impregnation liquid with the fiber residue such that the fiber residue adsorbs the concentrated corn impregnation liquid, and drying the mixture to prepare sprayed corn bran,
- wherein in step b), an enzyme preparation is added during the separation of the fibers from the starch and proteins.
