Interpretive Summary:

Technical Abstract: Isoflavones and saponins are the major unique phytochemical constituents of soybean seeds. They are essential in preserving the health of germinating seeds, and have been implicated in biochemical roles in both human and animal nutritional health. The accumulation of these compounds in developing seeds are affected by both cultivar genetics and environmental factors and can vary considerably from location to location and year to year. Measuring these compounds is both complex and exacting, requiring special care in sample preparation and full identification of the various forms accumulated in the beans. Developing efficient and accurate near infrared spectrophotometric quantitation methods is vital for accurate evaluation of the levels of these compounds in lots, and processing plants. We are accumulating a large set of NIR scans and wet chemistry analytical data from soybeans grown in all the bean production areas of the United States and over successive crop years. We are using this large collection of data to evaluate more accurate calibrations using the NIR technology.
