| Résumé : |
This work is part of a project to produce food emulsions like mayonnaise and salad dressing, using a vegetable protein from Lupinus albus seeds to fully replace the egg yolk.
There are several variables to control in order to achieve a good emulsion, i.e., with good physical properties and high stability. Other authors have referred the ability to unfold at the interface as a main requirement for a protein to be a good emulsifier. This property can be enhanced by chemical, enzymatic or physical modifications of the protein conformation. In a previous work, the controlled thermal denaturation, increasing the protein unfolding and improving its surface hydrophobicity was the modifying process selected to improve foaming ability of lupin proteins. |
