Spelt is a very valuable reintroduced pre-industrial grain. Spelt preservation has been mostly focused on pest control. The knowledge gained by VacQPack on spelt preservation is critical. The VacQPack system promotes maintenance of the original sensory attributes of spelt, protecting the stored grain against moisture and cross infestations. It also effectively fights any detected weevil and/or moth infestation.
VacQPack’s organic compliant approach can replace:
• Fumigation practices like phosphine, being chemical free
• Silo bags, being easier to handle and transport
• Container liners, with the possibility to have an accurate measurement and control of Oxygen (O2) and Carbon Dioxide (CO2)/Nitrogen (N2) values
• Cold storage, being cheaper in terms of energy consumption and delivering high quality standards
For identified infestations of spelt, VacQPack uses the warehouse temperature to trigger egg hatching and kills the insects by anoxia —starvation of oxygen. To help this procedure, a flush of CO2 is recommended, a gas chosen by most quality managers as the form of organically compliant fumigation that best fights identified infestations.
Problems of condensation and evaporation due to uncontrolled high moisture content are also common in spelt storage. VacQPack fights them normally using Nitrogen N2, because it’s a very cheap organic treatment solution with a proven record in terms of yielding high quality grain.
Bugs have increasingly attacked harvested crops of spelt in recent years. Treatments like refrigeration, although effective, take too long, meaning higher expenses for treatment and storage.
The particularity of spelt is its thick seed husk which provides a natural protection from diseases and pests.
