Difference Between Mayonnaise and Butter

Food spreads have grown essentially important in the diet as they are known to improve the taste & flavor of the food items.

It becomes increasingly important to choose the right spread if you are moving to a healthy diet. Food spreads are known for their high saturated fat content & calorie richness (hence, they should be used sparingly & occasionally).

Choosing the healthier alternative gives an edge in maintaining one’s health.

Mayonnaise vs Butter

The main difference between Mayonnaise And Butter is that the mayonnaise is an oil-in-water type of emulsion (higher content of water than oil). On the other hand, butter is a water-in-oil type of emulsion (higher content of oil than water). In mayonnaise, the water content is derived from eggs & other liquids (like vinegar). In butter, the oil content is derived from animal saturated fats. 

Mayonnaise vs Butter

While there are many ways to prepare Mayonnaise, it is a white spread made primarily from three main ingredients, namely, vegetable oil, chicken eggs (usually only the yolk), and vinegar.

Additionally, they may even contain salt, sugar, mustard, and even lemon juice. It is a commonly used spread in burgers, sandwiches, and even salads.

As they contain vegetable oils, they are healthier due to the presence of unsaturated fats (and the absence of trans fat). 

Butter is a pale yellow dairy food made from cream. While preparing butter, the fat is separated from buttermilk. It is used as a spread as well as while cooking, roasting, toasting, and grilling.

It primarily contains saturated animal fat, milk proteins, and water. To avoid melting, butter is usually refrigerated.
