EFFECT OF SOAK TIME, SOAK TEMPERATURE, AND LACTIC-ACID ORE GERM RECOVERY PARAMETERS

To recover high valued corn germ from dry-milling ethanol facilities, corn was hydrated in under 12 hr and germ was recovered using traditio nal wet-milling recovery techniques. The optimal soak time and tempera ture for germ recovery was 12 hr at 59 degrees C. Germ was recovered b y flotation and skimming. Recovery levels of germ were near that of tr aditional wet milling. Results showed that soak time decreased with in creasing soak temperature up through 59 degrees C. A reduction in germ quality and quantity occurred at soak temperature of 75 degrees C.
