“…Nowadays, the production of decaffeinated coffees represents between 10 to 15% of coffee sales in the world 18,19,[64][65][66] , with the USA being the largest consumer; and more specifically, it is consumed by people who due to a health condition (eg, cardiovascular disease, insomnia, etc.) have to avoid consuming drinks that contain caffeine 4,40,66,67 .…”

“…One of the first decaffeination patents associated with this method was registered in favor of Francis R. Eden in 1917 67 . In general, the process takes approximately 8h 4 , and it proceeds as follows: a) Fresh coffee beans are immersed in hot water (93-104 °C) to solubilize the caffeine.…”

“…Coffee beans are incubated in a steam bath to open their pores and increase their moisture by 12 to 40% 4,22,70 , increase the solubility of caffeine and dissolve caffeine-based complexes with other molecules. Then, they are sprayed with dichloromethane, dichloroethylene, hexane, methylene chloride, diisopropyl ether or ethyl acetate (EtOAc) to solubilize and remove caffeine molecules 4,18,22,67,70 . The process takes approximately 10 h to remove the organic solvent from the coffee beans.…”

Caffeine is a secondary metabolite extensively studied for its stimulatory properties and presumed association with specific pathologies. This alkaloid is typically consumed through coffee, tea, and other plant products but is also an additive in many medications and confectionaries. Nonetheless, despite its worldwide consumption and acceptance, there is controversial evidence as to whether its effects on the central nervous system should be interpreted as stimulatory or as an addiction in which typical withdrawal effects are canceled out with its daily consumption. The following discussion is the product of an extensive review of current scientific literature, which aims to describe the most salient topics associated with caffeine's purpose in nature, biosynthesis, metabolism, physiological effects, toxicity, extraction, industrial use and current plant breeding approaches for the development of new caffeine deficient varieties as a more economical option to the industrially decaffeinated coffees currently available to caffeine intolerant consumers. Keywords: biosynthesis, decaffeination, extraction, metabolism, physiological effects, plant breeding.
