How much does a gallon of mayonnaise weight?

Answer 1

Mayonnaise, as defined by the U.S. Food and Drug Administration's Standard of Identity, must contain at least 65% oil by weight, vinegar, and egg or egg yolks. It may contain spices and natural seasonings except turmeric and saffron, whose yellow color might suggest added egg yolk. Preservatives such as calcium disodium EDTA are acceptable and approved for use in mayonnaise.

What Aunt Alice makes, however, doesn't have to meet the standard of identity, nor does "low fat" mayonnaise.

The density of edible oils at body temperature varies a little; canola oil is a little less dense, for instance, but most commercial mayo is going to use soy oil, because it's cheapest, and it's 91% as heavy as water. Egg is about 5% heavier than water, and cider vinegar is virtually the same as water.

A reasonable guess would make mayo 95% as heavy as water. A pint (two cups) is a pound (454 grams), the world around, so multiplying 227 grams by 95% would be 216 grams.

Depending on the recipe used, it would probably be 22 grams, plus or minus 5 grams.

Answer 2

A gallon of mayonnaise typically weighs around 8.6 pounds.

Answer 3

One US gallon of typical mayonnaise weighs 7.76 lb. This may vary depending on the recipe used.

Answer 4

5 pounds
