Although many near infrared (NIR) spectrometric calibrations exist for a variety of components in soy, current calibration methods are often limited by either a small sample size on which the calibrations are based or a wide variation in sample preparation and measurement methods, which yields unreliable results. Over the past two years our lab has used defined analytical methodology to measure 1) isoflavones and saponins in soy samples, and 2) the soluble carbohydrates (sucrose, raffinose, stachyose, verbicose, glucose and fructose) and “insoluble” carbohydrates (such as starch, cellulose, pectin and other structural carbohydrates) by hydrolysis to the monomer form and derivation to measure total insoluble monomers and total uronic acids. This analysis was done in triplicate on over 500 crop samples from the 2011 harvest and over 600 samples from the 2012 harvest. NIR calibrations have been developed from scans performed on the ground whole soy meal on three different NIR instruments using three different calibration development packages.

Poster Guidelines

The maximum size is the standard for scientific posters, 4-feet by 4-feet. Landscape is the typical orientation, but portrait is also acceptable as long as it isn’t wider or taller than 4-feet. The display boards will be numbered to indicate where to place your poster. Push pins will be provided to affix your poster to the board. Please stand by your poster during your designated poster session. Any posters remaining post conference will be discarded.
