Mayonnaise
Mayonnaise, a versatile condiment, is a creamy emulsion of oil, egg yolks, vinegar, and seasonings. Renowned for its rich texture and tangy flavor, it enhances sandwiches, salads, and various dishes. A culinary staple, mayonnaise's smooth consistency and ability to bind ingredients make it a go-to choice for chefs and home cooks alike, elevating the taste and texture of a wide array of culinary creations.
Mayonnaise is a thick, creamy sauce typically used as a condiment or spread. It is made from a combination of oil, egg yolks, vinegar or lemon juice, and seasonings such as salt, pepper and mustard. Because the product is an oil-in-water emulsion held together by egg yolk, the plant design question is less about heat and more about how consistently shear, dosing rate and sequence can be controlled.
Commercial production runs in five stages. Egg yolks and vinegar or lemon juice are mixed in a large vessel using a high-speed mixer until fully combined. The oil is then added slowly to the egg mixture while mixing continues at high speed, which is the emulsifying step that determines the body and stability of the finished sauce. Salt, sugar, mustard powder and other seasonings are added to the emulsion mixture to enhance flavour. The mayonnaise is then packaged in various sizes and types of containers, such as jars, bottles, pouches and sachets, and the packaged product is pasteurised by heating it to a specific temperature for a certain amount of time to ensure food safety and increase shelf life.
On the market side, the major players in mayonnaise are Unilever, Kraft Heinz, Nestle, McCormick & Company and Conagra Brands. North America is the largest market for mayonnaise, followed by Europe and Asia-Pacific. For a producer planning a new line, that mix of large branded incumbents and multiple pack formats usually shapes the format flexibility a plant needs to build in from the start.
