These figures show that the variation
found in the color parameter L, a, and b, values of
the paste samples was not significantly large
enough to show differences in the color. However,
some color parameter changes due to the effect of
heat treatment were found. Heat treatment had a
significant (P < 0.05) effect on L, with the color
parameter L values of samples heated to
temperatures higher than 60°C being higher than
in unheated samples, while values for color
parameters a and b, most of heated samples were
not different. It has been reported by Ahmed et al.
(2002) that any change in values for color
parameters a and b was associated with a
simultaneous change in the value of color
parameter L. As shown in Table 2, the relationship
between L and a was negative, while the
relationship between parameters L and b was not
significant.
