Mayonnaise is a staple condiment in many households, used in a variety of dishes from sandwiches and salads to dips and sauces. However, its creamy texture and high water content make it a potential breeding ground for bacteria, which can lead to spoilage and foodborne illness. If you’re wondering how long you can keep mayonnaise in the refrigerator, you’re not alone. In this article, we’ll delve into the world of mayonnaise storage and explore the factors that affect its shelf life.
Understanding Mayonnaise and Its Shelf Life
Mayonnaise is an emulsion of oil, egg yolks, vinegar or lemon juice, and seasonings. The acidity of the vinegar or lemon juice helps to preserve the mayonnaise by creating an environment that is unfavorable to the growth of bacteria and other microorganisms.
