Mayonnaise Nutrition Benefits and Facts

Nutritional summary

Mayonnaise is a shelf-stable emulsion that requires refrigeration only after the seal is broken; once opened, commercial varieties should be consumed within two months for optimal quality .
Freezing mayonnaise is not recommended because the process breaks the emulsion, causing the oil to separate and significantly degrading the texture .
Standard mayonnaise is defined by its oil content, typically containing at least 65 percent vegetable oil by weight, which accounts for its high energy density .
The impact of mayonnaise on blood lipid profiles (cholesterol levels) depends largely on the type of base oil used, such as soybean or palm oil, rather than the egg component alone .

Interesting fact

The name may derive from the city of Mahón, where it was allegedly discovered by French forces after the 1756 Battle of Minorca.
