Project Type: Specific Cooperative Agreement
Start Date: Aug 1, 2010
End Date: Jul 31, 2013
The objectives of this cooperative research are to 1) develop grain quality measurement methods to enable sorting for particular attributes of single seeds using near- and mid- infrared spectroscopy and 2) develop improved grain storage monitoring methods through the innovative use of carbon dioxide (CO2), relative (RH) humidity and temperature (T) sensing systems.
For the first objective, grain quality measurement methods using near- and mid-infrared reflectance spectroscopy (NIRS, MIRS) and other non-destructive methods will be developed to segregate single kernels based attributes such as protein, oil and starch. The focus will be to develop accurate and rapid methods (5 -10 kernels/sec) to measure basic seed composition or more subtle characteristics such as oil composition. The second objective will investigate the condition and effects of storage mold development during grain storage. This work will provide a better understanding and interpretation of CO2-RH-T measurements inside commercial grain storage. These systems are currently being introduced as commercial systems but there is a lack of understanding in data interpretation. Iowa State will facilitate trial installations of this equipment at commercial grain facilities.
