3.4. Color analysis
Color measurements of LF and FF mayonnaises
are shown in table 8. The lightness (L value) of
mayonnaise has a major impact on the perceived
appearance of the product. The L
*
values of LF
mayonnaise prepared with sunflower oil and
soybean oil at 45% level, were significantly
(P≤0.05) higher than those of FF mayonnaises.
The highest (P≤0.05) lightness among all
mayonnaise formulations was found in LF
mayonnaise formulated with soybean oil at 45%
level and XG/GG (1:1) combination at 0.75% level
as indicated by L
*
value (L
*
= 84.09). This is in
good agreement withMun, Kim [3] who stated that
the L-value of the FF mayonnaise was the lowest
and by increasing the level of starch and xanthan
gum, the L-value of the LF mayonnaise increased.
