Evaluation of emulsion stability and L*, a*, b* values of emulsions produced at different homogenizing speeds and times
| Speed (rpm) | Mixing time (min) | Emulsion stability (%) | Creaming index (%) | L* | a* | b* | |
|---|---|---|---|---|---|---|---|

‘-’indicates that the emulsion was not separated. L* represents lightness (100 = white; 0 = black). a* indicates redness when positive, greenness when negative. b* indicates yellowness when positive, blueness when negative. Values are presented as means ± standard deviations. *a Values with different superscript letters indicate significant difference at p < 0.05
