ANOVA was not sensitive enough to differentiate
between the soaking in saline or in water, because it
cannot take into account the pairwise character of the data.
The appropriate pairwise t-test showed significantly lighter
chips as a result of the saline soaking at all temperatures.
The chromatic components b, which range from blue to
yellow (120 to +120), and a, which range from green to
red (120 to +120), of potato chips change with the
temperature and the soaked treatment used; the color
parameters lightness (L) show differences clearer than
those obtained using the parameters a and b (data not
shown).
