Changes in the Quality of Soybean during Warehouse Storage

Large warehouse, being considered as the general type of storage granary in China, has proven to be the key post-harvest management in the fight against food security for long periods storage. Soybean (Glycine max) seeds bulk stored under ambient condition (the control) and mechanical ventilation (the test) for 12 month were analyzed for some physico-chemical characteristics to investigate the effect of storage condition on the quality of soybeans. The results indicated that the samples storied in texted storehouse had a lower level of the free fatty acid content. There was a notably higher water solute protein content compared with the samples in controlled storehouse, which effectively reduce the deterioration of water-soluble protein quality and respiration rates. These results provide convincing evidence that tested warehouse obviously superior to conventional storage, which can delay the quality deterioration of soybean seeds quality and has good prospects for application.
