Cserhalmi, Sass-Kissb, Tóth-Markusb, and Lechnera (2006) reported
that the difference in color could be classified in relation to the
sample ΔE as not noticeable (0–0.5), slightly noticeable (0.5–1.5),
noticeable (1.5–3.0), well visible (3.0–6.0) and great (6.0–12.0).
Thus the juice homogenized at 50 MPa showed noticeable variation
in color and those homogenized at 75 and 100 MPa showed a well
visible difference in color as compared to the standard (Fig. 8;
Table 2).
