Based on the results obtained, the flours used in this study can be considered to show similar behavior to guar and xanthan gums in mayonnaise processing. Thus, they could represent a suitable option to replace commercial emulsifiers.
Table 2 shows the mean values for the color parameters L*, a* and b* for the mayonnaise samples prepared with different additives. All samples showed high lightness (L* >72) with a yellow tone (þb*) and green pigment traces (-a*). The lightness (L*) of the UF sample did not differ significantly from that of TF, guar gum and carrageenan. Amin et al. (2014) evaluated the color of mayonnaise samples prepared from a mixture of soybean oil, xanthan gum and guar gum, and observed lightness values ranging from 70.06 to
84.09.
