Extraction of Cannabinoids
摘要
Chapter 3 explores the main extraction technologies used to obtain cannabinoids from Cannabis biomass, highlighting how process choice influences yield, selectivity, and extract quality. It begins with conventional solvent extraction, outlining its principles, advantages, and limitations in terms of efficiency and sustainability. Emerging and intensified techniques, including ultrasound-assisted and pressurized liquid extraction, are then discussed as strategies to enhance mass transfer while reducing solvent use and processing time. The chapter also presents supercritical fluid extraction, emphasizing its tunability, solvent-free nature, and industrial relevance for producing high-purity cannabinoid extracts. By comparing these methods through mechanistic insights and practical considerations, this chapter equips readers with a clear understanding of how extraction technologies determine cannabinoid recovery, scalability, and application across different sectors.
