Cannabis inflorescences were stored for four months (d130) in the dark. The inflorescences were stored either in a polyethylene plastic sealed package (“air”, CD-200 impulse heat sealer, Carerite, Woodland Hills, CA, USA) or under vacuum (“VAC”, Chemical Duty Vacuum Pressure Pump, MilliporeSigma, Burlington, MA, USA). The storage temperature was set to 4 °C, which was found to be superior in terms of cannabinoid and terpene content preservation for a prolonged storage time as compared to the other temperatures examined previously [19 (link),20 ].
During storage, four different groups were examined, namely, the reference group that was stored in a polyethylene plastic sealed package (“REF-air”), the reference group that was stored under vacuum (“REF-VAC”), the hexanoic acid group that was stored in a polyethylene plastic sealed package (“Hex8mM-air”), and the hexanoic acid group that was stored under vacuum (“Hex8mM-VAC”).
