                                According to the food safety authority EFSA, an enzyme derived from hens’ egg whites, known as lysozyme, is sometimes used as a preservative in the production of certain ripened cheeses. This means that some cheese does have eggs, or at least egg-derived components, a crucial detail for those with egg allergies or following specific diets.
