Bio treatment of soybean seeds
Soybean seed preservation is critical to maintain its germination potential, for protection against mechanical injuries and to inhibit deterioration from peroxidation.
The three major influences distressing the conservation of soybean seeds are moisture content, temperature and duration of storage.
Taking a closer look, the soybean seeds’ preservation encounters high content moisture levels, which increases seed mycoflora and endorses the rapid deterioration of soybean seed quality and viability during storage. This seed is also highly susceptible to mechanical stress and damage during post-harvest handling, which will disturb its viability and vigor during storage. Finally, the soybean seed is an hygroscopic material and will either lose (desorb) or gain (adsorb) moisture from the immediate atmosphere; this is correlated with the rapid seed degradation of soybean along with lipid peroxidation, resulting in loss of seed viability.
To guarantee the quality of soybean seed during storage VacQPack flexible bulk packaging delivers an organic fumigation solution for the preservation of the soybeans seeds, using low pressure (vacuum) combined with modified atmosphere MAP and storage temperature (>24C).
This approach can simply substitute the cold chambers used currently for preservation by refrigeration, meaning less expenses on heavy infrastructures and energy bills. For natural hot and dry climates such in center of Brazil, tests have shown that the mobile Cleanpack can perform in the most remote areas, needing only access to 230V plug, and the Brazilian average high temperature is a bonus on the storage conservation of soybean seeds.
Problems of condensation, excess of humidity and loss of quality on the long haul storage are solved, because the VacQPack liners are composed of a EVOH gas barrier layer, with very low oxygen and water vapor transmission rate, which will maintain the programmed inner atmosphere values and keep way any negative effects from the outside variations on humidity and temperature.
On the other hand and taking advantage of the “three weapon system”, high natural environment temperature will hatch the eggs and the lack of oxygen will kill any remaining of insect presence, like: Granary weevil, Khapra beetle and the Almond moth.
Soybeans seeds contain antioxidants and phytonutrients that have been linked with various health benefits. Aside from water, soybeans are mainly composed of protein, but they also contain good amounts of carbs and fat.
For a better preservation, an air-tight container is commonly recommended, with opaque characteristics and stored at room temperature.
