Information And Results
Project Deliverables

Outputs and deliverables include NIR spectra, data of HPLC and GC-MS in terms of amino acids and digestible energy in soybean seeds and toasted meals, digestibility data from in vitro study, feces analysis of the in vivo study (animal study) as well as NIR calibrations.

Final Project Results

Achieving the objectives
The following achievements were made that address KPI’s 1 and 2:
• Analysis was completed for soluble sugars, insoluble carbohydrates, uronic acids, isoflavones, and saponins of over 600 samples from the 2012 harvest. Two manuscripts are being prepared further documenting this work, one for carbohydrate NIR analysis and another for isoflavone and saponin analysis.
• A set of 24 soybean mixtures were prepared and soluble sugar, insoluble sugars, isoflavone and saponin analysis was performed using both wet chemistry and NIR. Whole bean samples were toasted, ground, measured with NIR, a portion saved for digestibility studies, and another portion defatted and wet chemistry analysis. Of these 24, 10 mixes were chosen for three model digestibility studies and one rooster feeding study based on total soluble sugar analysis.
• With uronic acid analysis, we determined total soluble sugars between 8-12%, and total oligomer sugars (insoluble) at 6-10%, and uronic acids 10-14%, giving us a range of total carbohydrate values of 24-36%.
• The results of the digestibility studies on the toasted samples showed there was no obvious correlation between soluble sugar content and these in vitro digestibility model results.

Not achieving the objectives
• KPI #3 has not been fully met at this time, however significant progress has been made and related work continues through project 1420-832-8274. With the inclusion of fall 2014 data and analysis, USB will be better prepared to carry results to NIR manufacturers and this KPI will be met. We anticipate meeting this objective in the future through the new project.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
