non-fat mayonnaise

Non-fat mayonnaise is a reduced-calorie emulsified condiment designed as a substitute for traditional mayonnaise, which derives most of its calories and richness from oil. Unlike classic mayonnaise (which contains 80-90% oil by weight), non-fat versions replace the majority of oil with water, starches, gums, and emulsifiers to achieve a comparable consistency and spreadability. The emulsion is stabilized through the use of egg yolks (or their derivatives), vinegar, salt, and food additives such as xanthan gum, modified food starch, and sometimes carrageenan. The result lacks the characteristic richness and mouthfeel of traditional mayonnaise, with a lighter, sometimes slightly gelatinous texture and less pronounced flavor intensity.

Non-fat mayonnaise functions as a direct substitute in applications where mayonnaise serves primarily as a binder or spreadable base, such as sandwiches, salads, and cold preparations. It is commonly used in potato salad, coleslaw, deviled eggs, and tuna salad to reduce overall fat and calorie content while maintaining textural similarity. However, its reduced fat content makes it less suitable for applications requiring emulsification stability in warm contexts or where the richness of oil is essential to the dish's character. It works best in cold or room-temperature applications and should not be used as a cooking medium or base for warm sauces.
