How long does mayonnaise in pasta salad stay fresh the refrigerator?

Mayonnaise-based pasta salad will typically stay fresh in the refrigerator for 3-5 days.

Here are some factors that can affect its shelf life:

* Quality of ingredients: Using fresh, high-quality ingredients will help extend the shelf life.

* Storage temperature: The refrigerator should be kept at a consistent temperature of 40°F or below.

* Type of mayonnaise: Homemade mayonnaise tends to have a shorter shelf life than store-bought varieties.

* Other ingredients: Some ingredients, like tomatoes or cucumbers, can break down faster and shorten the salad's shelf life.

To ensure your pasta salad stays fresh:

* Store it in an airtight container: This prevents it from drying out or absorbing other odors.

* Avoid overpacking the container: This allows for better air circulation.

* Don't add ingredients until just before serving: Some ingredients, like lettuce or spinach, will wilt quickly in the refrigerator.

Remember, it's always best to err on the side of caution and discard any pasta salad that smells, looks, or tastes off.
