  • Selective deactivation of yeast in corn wet milling process slurries
    Publication number: 20030138935
    Abstract: A method of treating an aqueous medium of the type having yeast and lactic acid producing bacteria therein, such as a corn wet milling process, is disclosed. An effective amount of octanoic acid is added to the medium to reduce the yeast content in the aqueous medium while leaving the lactic acid producing bacteria viable.
    Type: Application
    Filed: January 23, 2002

    Inventor: William J. Palardy
  • Treatments to improve yields in the wet milling of corn
    Patent number: 5932018
    Abstract: A process to enhance the physical separations in the wet milling process is disclosed. Specifically, a nonionic surfactant esterified with fatty acids acts to reduce the starch content of fiber in the wet milling process, thus increasing the quantity of starch recovered for subsequent processing into higher value products.
