Presentation Transcript

  1. Impact of deficit irrigation on grain properties and ethanol yield D. Wang, L. Liu, N. Klocke, D. Rogers, F. Lamm, and A. Schlegel Biological and Agricultural Engineering Kansas State University Manhattan, KS 66506 2013 OAP Workshop, March 5-7, 2013, Amarillo, Texas

  2. Objective Objective: to study the effect of deficit irrigation on the physical and chemical properties and ethanol yield of corn and grain sorghum. thermal rheological

  3. Materials and Methods

  4. Grain and irrigation treatment (1=full irrigation and 5=low irrigation)

  5. Physical properties Breakage susceptibility Single kernel properties Test weight Microstructure (SEM) Thermal property (DSC) Pasting property (RVA)

  6. Chemical compositions

  7. Ethanol fermentation Sorghum <3% Corn ~97% ~37% used for corn ethanol In 2011, US ethanol production reached 13.90 billions of gallons. Source: RFA

  8. Results

  9. Physical properties Sorghum Corn

  10. Effect of rotations and irrigation levels on corn physical properties

  11. Chemical properties Sorghum Corn

  12. Effect of rotation and irrigation level on corn chemical properties

  13. Effect of irrigation on microstructure Sorghum SEM images of starch granules and protein matrix in sorghum endosperm Irrigation level -1 Irrigation level -2 Irrigation level -3 Irrigation level -4 Irrigation level -5 • High irrigation level’s starch granules were bigger, had smooth surfaces and few protein bodies around individual starch granules.

  14. Effect of irrigation on microstructure Corn SEM images of starch granules and protein matrix in corn endosperm (GS-Corn): Irrigation level -1 Irrigation level -2 Irrigation level -3 Irrigation level -5 Irrigation level -4 • High irrigation level’s starch granules were bigger than those with low irrigation levels.

  15. Pasting properties Sorghum Corn • Starch pasting temperature was significantly increased as irrigation level decreased. • Peak pasting viscosity and set back viscosity was decreased as irrigation level decreased.

  16. Effect of rotations and irrigation level on corn starch pasting properties

  17. Thermal properties Amylopectin Amylose Sorghum Corn GS-Corn

  18. Ethanol yield and fermentation efficiency • ~ 8% between high and low. Sorghum • ~ 5% between high and low. Sorghum

  19. Ethanol yield and fermentation efficiency as affected by different rotation

  20. Effect of irrigation on fermentation efficiency Sorghum Sorghum Corn Corn

  21. Comparison of corn and sorghum for biofuel Grain production, lbs/acre Sorghum advantage at lower moisture Sorghum Corn Inches/acre • Corn: 2.85 gal/bu with 95% efficiency at 56 lb/bu. • Grain sorghum: 2.76 gal/bu with 93.8% efficiency at 56lb/bu.
