Methods of preventing grain sprouting after harvest through the application of sulfur dioxide, nitrogen and ammonia gases
First Claim
1. A method of treating storage grain, such as corn, wheat and sorghum to prevent sprouting of said grain under suitable moisture conditions comprising applying nitrogen gas to said grain in amounts sufficient to enhance the anti-sprouting activity of sulfur dioxide with respect to said grain and at about the same time applying sulfur dioxide gas to said grain in amounts effective to prevent said sprouting, whereby the anti-sprouting activity of said sulfur dioxide is effectively enhanced by said nitrogen gas.

Abstract
Novel methods for treating grain, particularly wheat, to prevent sprouting are disclosed. These methods include applications of sulfur dioxide gas to grain in amounts which are effective to prevent sprouting. In an alternate method, nitrogen gas is applied to grain to enhance the anti-sprouting activity of sulfur dioxide. Ammonia gas may also be subseqently perfused into the treated grain mass in amounts which are effective to preserve the color, odor and flavor of the grain, and to minimize the corrosiveness of the aforementioned sulfur dioxide treatment. Concurrent application of carbon dioxide gas and ammonia gas is also disclosed as reducing sprouting.
