Monitoring of new binary systems for caffeine extraction from natural raw materials
Abstract
The article summarizes the results of monitoring new binary systems for caffeine extraction (dispersion method) from natural raw materials using Camellia sinesis L. leaves and Coffea arabica L. beans as an example. Tea (Camellia sinesis L.) in the Russian Federation is grown in the Krasnodar region, so modification of methods of caffeine maceration from this raw material will certainly increase the potential of Russian production of this alkaloid. In turn, such methods, as more environmentally friendly, will eventually be able to replace the existing methods of condensation of cyanide-containing reagents and amides with urea (Traube method). Binary combinations of "ethyl acetate/aliphatic alcohol" in various ratios were used as the organic phase of the new, more economically advantageous systems, and the classical chloroform extraction method was chosen as the comparison method. In this research, the aliphatic acyclic saturated alcohols in different structural forms were analyzed as the second component of the organic phase of the extraction system. As a result, it has been proven that new extraction systems allow for a more complete extraction of caffeine from natural components. Modification of the extraction process will produce pure and environmentally friendly caffeine from natural raw materials, and will provide an economically suitable caffeine production process for the domestic producer.
