Abstract

Tea is one of the most consumed beverages in the world, being considered one of the oldest drinks produced by biotechnology developed by the human being. Its use occurs in the form of infusions and its ample consumption is related to its sensorial and stimulating properties. The chemical composition of the leaves of black tea (Camellia sinensis) and mate (Ilex paraguariensis) is quite diverse with the presence of a wide variety of components. Black tea (Camellia sinensis) has high concentrations of compounds that have antimicrobial properties, as well as the herb mate (Ilex paraguariensis), and can be exploited for the use of preservatives in foods, for example. In order to use these natural products it is necessary to carry out an extraction process to remove the biologically active compounds from the raw material matrix and for this different techniques and extraction methods can be used. These extraction techniques range from the simplest, such as maceration, to advanced processes such as pressurized liquids (PLE). Conventional methods of extraction have disadvantages, such as low selectivity, low concentration of compounds of interest, delay in extraction time and high solvent consumption to obtain the compounds. In contrast, modern extraction techniques allow the process to be carried out more quickly with lower solvent consumption and extracts with higher concentration and less contaminants. The aim of this work is to study the combination of pressurized fluid extraction and solid phase extraction for the purification of phenolic compounds from black and matte tea, as well as to evaluate the antimicrobial potential of the flavonoid fraction and its use against pathogenic and deteriorating microorganisms.
