I am working on a mayonnaise recipe, that could have at least 2 -3 weeks shelf life (refrigerated). I have access to pasteurized egg yolk, and white.

I believe there will be a longer shelf life using egg white only, but how to evaluate it accurately?

Thanks in Advance

  • Hi, I made your question title better match the specific question in the body text. A general question on the shelf life of mayonnaise would have to be closed as a duplicate.

  • If you're not using egg yolk, what is the emulsifier?

  • Egg white can work as emulsifier too

There is no difference in the shelf life of mayonnaise made with egg whites, or egg yolks, or whole eggs. Since you are using pasteurized eggs, this counts as a standard cooked dish, and the shelf life is 3-5 days in the fridge. It would be 1-2 days for raw eggs.

You cannot evaluate the safe shelf life of a food by yourself. In principle, one could commission a microbiological study to prove that a given recipe is somehow longer lasting than one would expect from its general category. That is likely to cost more than hiring a cook to make you a daily batch of mayonnaise for the next few years.

For more information on food safety, I would suggest that you also look at the extensive information we have compiled on the topic: https://cooking.stackexchange.com/tags/food-safety/info

  • Thank you for the answer. After checking with my supplier egg yolk have 5 days shelf life, and egg white 10 days. What could be used as an emulsifier to replace the egg?

  • The shelf life of each ingredient doesn't matter. The new dish has its own shelf life, which can easily be shorter than the shelf life of the ingredients.
