Can fat free mayonnaise be used as a binding agent?

Yes, fat free mayonnaise can be used as a binding agent. One benefit to using fat free mayonnaise as a binding agent, other than having a lower content of saturated fat compared to mayonnaise with fat, is the binding capabilities provided by other ingredients such as eggs and xanthan gum. However, fat free mayonnaise tends to not produce a binding structure that is as solid as mayonnaise with eggs.
