Kewpie Mayonnaise has been Kewpie’s flagship product since its launch in 1925 and is the No.1 market share in Japan*. Kewpie Mayonnaise contains four egg yolks per 500g. The amino acids from the protein in the yolks are the key to its tasty and savoury flavour, which makes it different from other mayonnaise. With no chemical preservatives, Kewpie Mayonnaise is naturally preserved with vinegar and salt and comes in a special squeeze bottle designed to keep oxygen out. *Source: INTAGE SCI 2021 in Japan
