* Mean \(\pm\) standard deviation; the different letters indicate a significant difference at \(p<0.05\) for the two-way ANOVA and Tukey post hoc test. GTL—dried green tea leaves (0.5 g); WHF—dried white hibiscus flowers (0.5 g); RHF—dried red hibiscus flowers (0.5 g); CP—dried chokeberry pomace; 2.0, 2.5 and 3.0—indicate pomace addition in g.

Table 3: Influence of dried chokeberry pomace addition to green tea leaves or hibiscus flowers on the anthocyanin content of infusions. added. In turn, for hibiscus flowers, a comparable content of anthocyanins was obtained after adding 3.0 g of chokeberry pomace (Table 3). The higher content of anthocyanins in the infusions obtained from green tea leaves with 2.5 g of chokeberry pomace added may be the result of co-pigmentation with phenolic compounds. Such an effect was studied by [PERSON] et al. [27], who indicated the participation of phenols present in green tea, such as catechin, epicatechin or chlorogenic acid, in the co-pigmentation of anthocyanins from chokeberry pomace. Co-pigmentation with a phenolic compound consists of creating complexes by charge transfer or \(\pi\)-\(\pi\) interactions. These processes result in a greater stability of anthocyanins, as well as bathochromic (a wavelength shift to longer wavelengths) and hyperchromic effects (an increase in absorption intensity). However, taking into account the instrumental and sensory assessment of the color, the higher content of anthocyanins did not result in a better color of the infusions compared to the hibiscus infusions, especially with the addition of 2 g of chokeberry pomace to the green tea leaves (Figure 2). This may be the result of both a greater share of yellow and green colors in green tea infusions (Table 2), as well as a higher pH value (Figure 1). At a lower pH, which is characterized by hibiscus infusions, the proportion of red flavylium forms is dominant [44]. Also, the presence of minerals in tea infusions (from used ingredients), such as metal ions, could affect the spectral characteristics of anthocyanins and, as a result, their content.
