What makes your potato salad spoil?

The star ingredient of potato salad is the potato, which has a long shelf-life.  Potato salad has plenty of mayonnaise, and eggs which spoil within a few days. 

Eggs carry salmonella bacteria that is a highly prevalent cause of food poisoning. Salmonella is potentially present in eggs which, gradually multiply and causes the egg to spoil.

Eggs are the quickest ingredient to spoil in a potato salad. Your food lasts only as long as the ingredient, which spoils first. In a potato salad, it is the egg.

Mayonnaise has preservatives that prevent it from spoiling even when put together as a food ingredient. 

Homemade mayonnaise can spoil in a couple of days. The constituents of mayonnaise; eggs and, oil are highly perishable. Oil tends to go rancid as a result of the oxidation reaction.

However, if you used store-bought mayonnaise, you do not have to worry.

If you have vegetables or herbs added, such as onions or celery, they also tend to wilt after a while.

Even though they may not spoil as soon, but they lose their freshness.

Can you freeze your potato salad?

You can not freeze your potato salad if you have mayonnaise added to it. Mayonnaise is sensitive to temperature change because it is an emulsion. An emulsion is a blend of liquids that will not mix unless agitation or an emulsifier is used.

When you freeze, the temperature shock will bring the oil and eggs apart and disintegrate your salad.

 Even though your salad will still be safe for consumption but this will deteriorate its quality.

In case you did not add mayonnaise to your salad, you can freeze your potato salad without compromising the quality.
