Corn distillers' dried grains with solubles (CDGS) and corn distillers' dried grains (CDG) at various moisture and fat contents were pin milled and screened. Fractions of CDGS and CDG contained from 11.4–45.7% and 12.5–49.6% protein, respectively (dry basis), compared with 30% for CDGS and 25% for CDG. The highest protein shifts were obtained when CDGS at initial moisture of 21% was ground twice at 14,000 rpm and CDG at initial moisture of 21% was ground once at 14,000 rpm. Fat, ash, dietary fiber contents, and amino acid composition of CDGS and CDG fractions were also determined.
