The extraction method of green Robusta coffee beans using NADES solvent synthesized from xylitol and lactic acid

Abstract

   NADES (Natural deep eutectic solvent) is a solvent made from naturally derived, bio-based compounds that are environmentally friendly and have the potential to replace other organic solvents in fields such as extraction, separation, and biomedical sciences. The study investigates the efficiency of green Robusta coffee bean extraction using NADES solvent to reduce the caffeine and chlorogenic acid content in the coffee beans. The results show that the extraction method reduced the caffeine content by 18.09% and the chlorogenic acid content by 9.06% in Robusta coffee beans compared to the initial levels. As a result, the extracted coffee beans have the potential to be developed into low-caffeine coffee products, catering to consumer demand.
