ABSTRACT:
The present invention provides a method of retarding rootlet formation from one or more plants in a medium that can support the growth thereof, which method includes introducing into the medium a growth inhibiting effective amount of a growth inhibitor which comprises corn steep liquor. In other embodiments, the growth inhibitor is a mixture of a growth medium and lactic acid. In preferred embodiments, the present invention further provides a malting composition that includes a fermentable grain and a growth inhibitor, wherein the growth inhibitor is present in an amount effective to retard rootlet formation.
