RECOVERY OF STARCH AND PROTEIN FROM WET-MILLED CORN FIBER

Physical and chemical methods were used to recover starch and protein from wet-milled corn fiber. A single milling of the fiber produced an 18% yield of mill starch. By separating the mill starch with a starch table, 68% of this material was recovered as starch with a protein con tamination of 0.66%. Milling increased fine fiber from 4.5% in the sta rting material to 11.5% after a single grind. Successive additional mi lling passes modestly increased the mill starch and fine fiber yields with a corresponding decrease in the coarse fiber yield. Pretreatment with combinations of lactic and sulfurous acids had only a small effec t on the distribution and composition of the recovered fractions.
