This document specifies a method to classify six tea types (black tea, green tea, white tea, oolong (blue) tea, dark tea and yellow tea) based on statistical analysis of chemical compositions. The key X1 to X6 determinants (total catechins, caffeine, theanine, epigallocatechin gallate (EGCG)/total catechins, theanine × theanine, theanine × caffeine) for tea chemical classification were extracted from these critical compositions by statistical methods, from a large-scale chemical analysis of samples of six tea types, which can be used as principal components to classify the particular tea by Fisher’s step-by-step discrimination formulae.[6][7] This document is applicable to the classification of both primary and refined teas, and is particularly suitable for teas produced in China. It does not apply to reprocessed teas.

In addition, this method has also been studied by inter laboratory trial via the analysis of samples containing incurred acrylamide, ranging from approximately 200 μg/kg to 2 000 μg/kg. Critical points of the method are identified in 7.5 and Clause 8.

This European Standard specifies a method for the determination of acrylamide in bakery ware such as bread, toasted bread, crisp bread, butter cookies, and biscuits, as well as potato products such as potato chips, potato crisps, and potato pan cake and roasted coffee, by liquid chromatography in combination with electrospray ionization and tandem mass spectrometry (LC-ESI-MS/MS). This method has been validated in an interlaboratory study via the analysis of both naturally contaminated and spiked samples, ranging from 14,3 µg/kg to 9 083 µg/kg. It was developed at the Swedish National Food Administration and validated in a study organized by the Directorate General Joint Research Centre (DG JRC), Swedish National Food Administration and the Nordic Committee on Food Analysis (NMKL), see [1] and [2].
The limit of quantification (LOQ) depends on the type of instrument used and on the actual performance of the instrument. The majority of the laboratories participating in the validation study were able to determine acrylamide in a butter cookie sample at a level of 14,3 µg/kg. Thus, the validation by interlaboratory study showed that LOQ can be expected to be in the range between below 15 µg/kg and 30 µg/kg.
