ABSTRACT:
Novel sequential gas treatments for preserving grain are disclosed. Sulfur dioxide gas which has been bubbled through an organic acid, such as propionic acid, is perfused through grain to be treated and permitted to react with that grain for a preselected period of time, to produce a preserved grain product. This grain product is then preferably perfused with ammonia gas. Alternatively, residual sulfur dioxide may be dispersed within the treated grain mass through the introduction of a carrier gas prior to ammonia gas perfusion. Other preservative methods and substances are also disclosed which provide superior preserved grain products.
