Introduction: Understanding Mayo Shelf Life
Mayonnaise, a popular condiment made from a mixture of oil, egg yolks, vinegar or lemon juice, and seasonings, is a staple in many households. However, as with all perishable foods, mayo has a limited shelf life. Understanding mayo’s shelf life is crucial to ensure that you are consuming safe and fresh mayonnaise.
Factors That Affect Mayo Shelf Life
Mayo’s shelf life is affected by various factors, including the ingredients used, the packaging, and how it is stored. The type of oil used in the mayo affects the shelf life, with those made with olive oil lasting longer than those made with vegetable oil. The packaging also plays a role in the shelf life, with those stored in clear jars or containers being more prone to spoilage due to light exposure. Finally, how mayo is stored, such as in the fridge or on a shelf, also affects its shelf life.
How Long Does Opened Mayo Last?
Once opened, mayo can last for up to two months in the fridge. However, its shelf life can vary depending on the factors mentioned earlier. Mayo stored in a clear jar or container may spoil faster, while mayo made with vegetable oil may not last as long as those made with olive oil. It is essential to check the expiration date on the packaging and discard any mayo that has gone past its expiry date or shows signs of spoilage.
Signs of Spoiled Mayo
Mayo that has gone bad will have a sour smell and taste, and you may notice changes in its texture, such as it being runnier or thicker than usual. Additionally, discolouration, mould, or separation can indicate that the mayo has spoiled. If you notice any of these signs, discard the mayonnaise immediately.
Proper Storage of Mayo
To ensure that your mayo stays fresh for as long as possible, store it in the fridge at or below 4 degrees Celsius. Additionally, keep the mayo in its original packaging, or transfer it to an airtight container. Avoid storing mayo in clear jars or containers that allow light to penetrate as this can cause the mayo to spoil faster.
Can You Extend Mayo’s Shelf Life?
While you cannot extend mayo’s shelf life, you can slow down the spoiling process by keeping it in the fridge and following proper storage guidelines. Additionally, adding ingredients like lemon juice, vinegar, or mustard to your mayo can help prolong its shelf life.
Mayo vs. Homemade Mayo Shelf Life
Store-bought mayo has a longer shelf life than homemade mayo due to the use of pasteurized eggs and preservatives. Homemade mayo typically has a shelf life of only a week, and it is essential to store it in the fridge and discard any leftovers after that period.
Mayo Safety Tips
When using mayo, ensure that you use a clean utensil and avoid cross-contamination with other foods. Additionally, if you are transporting mayo, keep it in a cooler or icebox to maintain its temperature.
