Did you Know? #4 - Vinegar and lemon juice as Preservatives

My Dear Sexy Readers,

Let's resume our serie "Did you Know". Last time we looked at how to make a mayonnaise and by understanding the chemical process behind it, how not to make a mess out of it! Today we are going to look at other ingredients we can add to a mayonnaise:

Vinegar, lemon juice and salts are used as natural preservatives

Lemon juice, vinegar and salt create an unfriendly environment for bacteria to slow down or stop their growth.

Bacteria need a wet environment to grow in. By adding salt to a product which will absorb all the humidity, you will basically dry it. This dry environment will be a bad niche for bacteria to grow and indeed can even be deadly for them!!

Lemon juice contains citric acid and vinegar, acetic acid, which both create an acidic environment where bacteria will not like for their growth...
(Note: Citric acid is added to cosmetics, pharmaceuticals, drinks and food.)
