Industrial hemp seed preservation is contingent on stabilization of moisture content (<8%), reduction of both oxidation and exposure to light, and the blocking of insect infestations. Industrial hemp seed preservation takes into consideration hemp seed’s high oil content, which is related to rancidity (measurable by peroxide values).
Thanks to the vitamin E present in hemp seeds, oxidation and rancidity are kept at bay by the seed itself. Still preservation measures must be applied if long term storage is needed, for which the use of an airtight container is common practice.
The VacQPack system can extend the shelf life and the quality of hemp seeds using its flexible hermetic VacQPack inner and/or exterior liner. Either of these packaging solutions delivers an organically compliant storage solution that keeps the hemp seed protected from any exterior menace, including adverse atmospheric conditions or any other specific storage condition.
VacQPack liners with an Ethylene vinyl alcohol (EVOH) gas barrier will ensure that the hemp seed moisture content is stabilized at a value below 8% (after an artificial drying process is applied).
This also means that variables like environmental temperature will not affect the germination rate of the cargo. Temperature will in fact play an important role in fighting identified plagues of insects, because at above 75ºF the VacQPack system protects against the menace of weevils and moths.
Extensive assessment has been conducted of the quality of hemp seed after long term storage using VacQPack technology. The overall result is that the shelf life is increased and quality parameters are secured.
