Research on horticulture and medical cannabis production for EXKA Inc

Our first project involves horticultural research and cannabis production, in collaboration with McGill University professor Mark Lefsrud. Medical cannabis is a developing field, but little information has been published on the production, harvesting, post-harvest processing (drying, grinding, storage) and extraction of the cannabis plant. The factors influencing the accumulation of terpenes, cannabinoids and other secondary […]

Breeding for powdery mildew resistance in Cannabis sativa: Strategies for improving resistance

Professor S. Jabaji, Plant Sciences, Faculty of Agricultural and Environmental Sciences, McGill University. Our second project focuses on plant breeding for resistance to powdery mildew in cannabis, in collaboration with McGill University professor Suha Jabaji. A fungal disease Powdery mildew is a foliar fungal disease that attacks most cannabis strains and is considered a problem […]

Cannabis chemistry, post-harvest processing methods and secondary metabolite profiling: A review

Main Lines Conclusion This study presents a summary of cannabis chemistry and secondary compound biosynthesis, as well as post-harvest processing practices along the cannabis product value chain that can affect cannabis phytochemistry, potency and volatility. The focus is on improving drying and extraction methods for plant material destined for the cannabis industry. Finally, new approaches […]

Cold ethanol extraction of cannabinoids and terpenes from cannabis using response surface methodology: optimization and comparative study

Main Lines Extracting secondary compounds from cannabis presents a number of challenges. Efficient extraction of cannabis biomass can increase yield while reducing costs and minimizing waste. Cold ethanol extraction was evaluated to maximize yields and concentrations of cannabinoids and terpenes at different temperatures. For me, this study is important because it enabled me to evaluate […]

Optimization of wiped-film short-path molecular distillation for cannabinoid recovery from cannabis oil using response surface methodology

Main Lines Conclusion This study provides distillation conditions to be taken into account by the cannabis industry if it wishes to obtain a cannabinoid-rich distillate from the molecular distillation process without affecting cannabinoid quality. Few studies have explored molecular distillation techniques that can improve cannabinoid recovery from crude cannabis oil with scale-up potential. Short-path molecular […]
