Evaluation of Analytical Methods to Determine Regulatory Compliance of Coffee Leaf Tea
The leaves of the coffee plant <i>Coffea</i> are traditionally used in several countries worldwide to prepare tea-like beverages using aqueous infusion in hot water. There are currently no tested methods available to check the regulatory compliance of coffee leaf tea according to the Eur...

description | The leaves of the coffee plant <i>Coffea</i> are traditionally used in several countries worldwide to prepare tea-like beverages using aqueous infusion in hot water. There are currently no tested methods available to check the regulatory compliance of coffee leaf tea according to the European Union (EU) novel food authorization. This study shows that standard ISO methods for tea analysis could be transferred without modifications to coffee leaf tea analysis. The only difference found was a much lower content of some catechins in coffee leaf tea compared to <i>Camellia sinensis</i> tea, but the methods were clearly applicable for use in controlling the EU’s maximum limits for coffee leaf tea. |
