The aw of regular mayonnaises was around 0.93 and that of diet ones was close to 0.95. The aw of mayonnaises was largely determined by the nature and concentration of soluble compounds in the water phase (e.g., NaCl, sugars, acetic acid). Experiments performed with mayonnaise and related oil/water emulsions demonstrated that emulsification did not contribute significantly to lowering of aw.
