How long does homemade mayonnaise typically keep in the refrigerator before it goes bad?

Question

How long does homemade mayonnaise typically keep in the refrigerator? Find out the average shelf life before your fresh mayonnaise goes bad.

Answer 1

Homemade mayonnaise typically lasts for 3-5 days in the refrigerator due to the use of raw eggs. Proper storage and handling are crucial to prevent spoilage.

Detailed Explanation:

Homemade mayonnaise is a delicious condiment, but it's important to be aware of its relatively short shelf life compared to commercially produced mayonnaise. This is primarily because homemade mayo is made with raw eggs, which can harbor bacteria like Salmonella. Commercial mayonnaise undergoes pasteurization, a heat treatment that kills harmful bacteria, extending its shelf life.

Here's a breakdown of why homemade mayonnaise doesn't last as long and how to maximize its freshness:

1. Raw Eggs: The primary reason for the short shelf life is the presence of raw eggs. Even fresh, high-quality eggs can contain bacteria.
2. Acidity: The acidity of the lemon juice or vinegar used in mayonnaise helps to inhibit bacterial growth, but it's not enough to eliminate the risk entirely.
3. Storage: Proper storage is essential. Keep your homemade mayonnaise in an airtight container in the coldest part of your refrigerator (usually the back).
4. Handling: Always use clean utensils when scooping mayonnaise from the jar to avoid introducing bacteria.
5. Smell and Appearance: Before using homemade mayonnaise, always check for any signs of spoilage, such as an off odor, discoloration, or a watery texture. If you notice any of these, discard it immediately.

To be on the safe side, it's best to consume homemade mayonnaise within 3-5 days of making it. If you're concerned about using raw eggs, you can find recipes that use pasteurized eggs or egg substitutes.

Pro Tip:

To extend the shelf life slightly and enhance flavor, add a clove of minced garlic to your homemade mayonnaise. Garlic has natural antibacterial properties that can help inhibit bacterial growth, and it adds a delicious savory note.
