**4. Conclusions**

Aquafaba-based vegan mayonnaises with blends of RRO and different cold-pressed oils were made. This research paper has presented that aquafaba from chickpeas is a suitable alternative emulsifier with high radical scavenging properties for the production of egg-free vegan emulsions. Moreover, the other ingredients of the proposed mayonnaise formulations, mainly nutritional yeas<sup>t</sup> and mustard, had high radical scavenging characteristics. Additionally, cold-pressed vegetable oils used as functional ingredients in developing vegan egg-free mayonnaises were rich sources of unsaturated fatty acids and natural bioactive compounds with scavenging radical properties.

The new aquafaba-based emulsions containing blends of RRO with different coldpressed oils had higher radical scavenging properties and oxidative stability, similar color parameters, and a smaller size of ODs than commercial vegan mayonnaise (MV). A significant contribution of the radical scavenging properties of the prepared vegan mayonnaises to enhance their oxidation status was observed. Additionally, emulsions with smaller areas of ODs had better oxidative stability.

The results of PCA indicated that the radical scavenging and physicochemical properties of aquafaba-based emulsions, commercial vegan mayonnaise (MV) and traditional emulsions containing egg yolk (MT1 and MT2) as the main emulsifier differ significantly.

Novel plant-based emulsions could be a promising alternative to egg-based mayonnaises and salad dressing. Further investigations should be performed to determine the effect of aquafaba on the textural and sensory properties and consumer acceptability of mayonnaise.
