  32. Understanding NIRVibrations of a (-CH2-) Group The atoms in a CH2 group commonly found in organic compound can vibrate in six different ways

  33. Unique NIR Calibrations LYSINE Proteins • Reactive Lysine – a measure of heat damage • SID Lysine

  34. Unique NIR Calibrations Processing of soybean and canola meals • Heat treatment – Lysine reacts with other compounds • Maillard reaction Lysine + reducing sugars → Maillard products • Maillard products – not nutritionally available REACTIVE LYSINE - Lysine that has not been destroyed by heat processing

  35. Unique NIR Calibrations REACTIVE LYSINE - Lysine that has not been destroyed by heat processing Kim and Mullan (2012)

  36. Unique NIR Calibrations The Reactive Lysine calibration identifies lysine molecules with a free epsilon amino group, which implies its availability for protein synthesis. A measure of heat damage REACTIVE LYSINE - Calibration

  37. Unique NIR Calibrations HEAT (Wet Chemistry) Total Lysine = Reactive Lysine + Reverted Lysine REACTIVE LYSINE - Lysine that has not been destroyed by heat processing

  38. Unique NIR Calibrations Lysine: • Essential amino acid – supplied through dietary intake • Total Lysine is not a measure of bioavailability • Reactive lysine – also known as available lysine Standardised Ileal Digestibility (SID) - Lysine • Accounts for basal endogenous losses • Lysine digested and absorbed from diet in the small intestine REACTIVE LYSINE - Lysine that has not been destroyed by heat processing

  39. Other Applications of NIR Machines

  40. Corn Flour Particle Size Whole Corn Applications

  41. Particle size Applications Average of the reference (yellow) and average of the NIR predictions (grey).

  42. Ground Corn – Particle Size Applications

  43. Applications

  44. Mixer Profile – 10 samples, NIR spectra Spectroscopy

  45. Mixer profiling Spectroscopy t1 t4

  46. Mixer Profile - % Coefficient of Variation Spectroscopy NIR gives a direct measure of mixability; all other methods report the mixability of a specific feed additive or component, and includes assay variation.
