Presentation Transcript

  1. Review of Rice Initiatives • Investigate use of NIRT to Determine Rice Surface Lipid Content • Investigate use of Scanner Technology to Determine Percent Broken Kernels in Rice • Richard Pierce

  2. Rough, Brown and Milled for Rice Classes

  3. Milling Degree • Visual assessment of the degree to which a commercial miller has removed the rice bran layers. • Terms used to describe milling degree are: • Hard milled • Well-milled • Reasonably well-milled

  4. Rice Surface Lipid Pilot Study - Goals Test Accuracy and Consistency of NIRT Calibration on Market Samples Obtain Data to Improve Performance of the NIRT SLC Calibration Assess Relationship between NIRT Surface Lipid Content (SLC), Reference Laboratory SLC, and Inspector Degree of Milling Assess Consistency of Field versus BAR Degree of Milling Determinations

  5. Rice SLC Range for Initial Samples

  6. Stuttgart NIRT vs TSD Master

  7. Determining Percent Broken Kernels A “Whole” Rice kernel is defined as 75 Percent or more of the Original Kernel Whole Kernels Large Broken Kernels

  8. Grain Check 2312 The Grain Check 2312 is an automated system for separating whole and broken kernels and providing comparable results to visual inspection. The Grain Check 2312 is discontinued and no longer supported!!!

  9. Scanner System for Rice Broken Kernels Challenges: Placement of Rice Kernels on the Scanner Platform Mathematical Algorithms to Identify Broken Kernels Low Cost Flatbed Scanner

  10. Original Image (300 dpi) from Scanner

  11. Binarized Image Using Intensity Threshold

  12. Whole Kernels

  13. Broken Kernels

  14. Thank you!
