A limited number of studies have examined how drying conditions affect the cannabinoid and terpene content in cannabis inflorescences. In the present study, we evaluated the potential of controlled atmosphere drying chambers for drying medicinal cannabis inflorescence. Controlled atmosphere drying chambers were found to reduce the drying and curing time by at least 60% compared to traditional drying methods, while preserving the volatile terpene content. On the other hand, inflorescences subjected to traditional drying were highly infested by and also revealed low infestation of . In the high-THC chemovar ("240"), controlled N and atm drying conditions preserved THCA concentration as compared to the initial time point (t). On the other hand, in the hybrid chemovar ("Gen12") all of the employed drying conditions preserved THCA and CBDA content. The optimal drying conditions for preserving monoterpenes and sesquiterpenes in both chemovars were C5O5 (5% CO, 5% O, and 90% N) and pure N, respectively. The results of this study suggest that each chemovar may require tailored drying conditions in order to preserve specific terpenes and cannabinoids. Controlled atmosphere drying chambers could offer a cost-effective, fast, and efficient drying method for preserving cannabinoids and terpenes during the drying process while reducing the risk of mold growth.
仅有少数研究探讨了干燥条件如何影响大麻花序中的大麻素和萜烯含量。在本研究中，我们评估了可控气氛干燥箱用于干燥药用大麻花序的潜力。结果发现，与传统干燥方法相比，可控气氛干燥箱可将干燥和熟化时间缩短至少60%，同时保留挥发性萜烯含量。另一方面，采用传统干燥的花序受到[未提及的某种物质]的严重侵染，且对[未提及的另一种物质]的侵染率较低。在高THC化学变种（“240”）中，与初始时间点（t）相比，可控氮和气氛干燥条件可保留THCA浓度。另一方面，在杂交化学变种（“Gen12”）中，所有采用的干燥条件均可保留THCA和CBDA含量。在这两个化学变种中，分别用于保留单萜和倍半萜的最佳干燥条件是C5O5（5% CO、5% O和90% N）和纯N。本研究结果表明，为保留特定的萜烯和大麻素，每个化学变种可能都需要量身定制干燥条件。可控气氛干燥箱可为干燥过程中保留大麻素和萜烯提供一种经济高效、快速且有效的干燥方法，同时降低霉菌生长的风险。
