MODIFICATION OF CORN GRITS TO PROVIDE SUPERIOR WATER ADSORPTION CHARACTERISTICS

摘要

Described are biodegradable desiccant compositions with superior water adsorption capacity, a preferred composition being a corn grit modified by reaction with an alpha-amylase under conditions effective to increase the desiccant capacity of the corn grits. The inventive compositions are useful in a wide variety of applications where conventional desiccants are utilized including, for example, systems for drying gases, such as air dryers, and processes for drying organics, such as ethanol purification processes. Also described are methods for making and using the inventive compositions.
