Table 4: Effect of sumac supplementation and plasma treatment on the color parameters of carrot juice stored in a refrigerator for 72 h.  
chromaticity parameter b* in this treatment variant had the lowest value (10.13), compared with the value recorded after 24 h (14.96). The total color difference (\(\Delta\)E) describes the color distance in the three-dimensional color space and refers to the difference between the color parameters of the control juice and the juice treated with cold plasma and/or supplemented with sumac powder. Depending on the value of \(\Delta\)E, differences in perceivable color can be analytically classified as very distinct (\(\Delta\)E \(>\) 3), distinct (1.5 \(<\)\(\Delta\)E \(<\) 3), and small difference (\(\Delta\)E \(<\) 1.5).
