Project Summary

In seasons of early frost or late planting, producers experience significant proportion of green or immature soybeans in their harvest. This green soybeans is consider loss yield because they are often removed to prevent significant discount at the elevator. Even though in some instances the surface green color fades, there is still concern that the inner green does not fade. There is no indepth research and information on how producers can manage the green soybeans from their harvest. Therefore, the goal of this project is to conduct a thorough study on how storage environment impact the maturity of harvested green soybeans. Soybeans seeds will be harvested at three stages that the producers will likely encounter. They will be stored at variable moisture contents and temperatures, and in the presence or absence of aeration and light. Color change will be regularly monitored both on the surface and internally using a colorimeter. Oil quality is more susceptible to change in storage compared to protein; therefore, it will be also analyzed. At the end of the study, we hope to provide producers with strategies to store green soybeans that will help increase their revenue stream.

Project Objectives

- Evaluate the physical appearance, primarily color, green and partially green soybean over time at different storage conditions (temperatures, initial moisture content, light, and aeration)
- Evaluate the effect of these storage conditions on oil quality, including free fatty acid and peroxide content.

Final Project Results

Benefit to Soybean Farmers

- Provide management strategies for when green or semi-green soybeans are harvested.
- Improves soybean quality thereby avoiding high discounts that are applied in years of large quantities of green soybeans
