How Long Does Homemade Mayonnaise Last In The Fridge
Homemade mayonnaise will last in the fridge for up to 2 weeks if stored correctly. This is because mayonnaise is made with raw eggs and without preservatives. Store-bought mayonnaise, on the other hand, can last up to 3 months in the fridge as it contains certain preservatives which increase the shelf life.
On average, homemade mayonnaise only lasts for about one week; and that is even if we keep it in the refrigerator. Even egg-free mayonnaises may last up to only 3-4 days, or a week at best, when they are homemade, because they have no preservatives.
Due to the raw egg usage, you will want to ensure you refrigerate your homemade mayonnaise soon after making. Before you actually choose to refrigerate your mayo, make sure that you move it into a suitable container.
You cannot leave the mayonnaise outside the refrigerator for longer than 8 hours, because mayonnaise gets contaminated with the bacteria found in its surroundings. These active enzymes will help you to store your homemade mayonnaise for relatively longer time in the refrigerator. It is important that you let the mayonnaise sit at room temperature before you put it into the refrigerator, because that will help the acids in the mayonnaise to destroy any kind of bacteria that might be present in the yolk.

If you use it as is and keep it refrigerated, it should last for 3-4 days, however, if you ferment the mayonnaise for 6 hours, it will last 2 months in the fridge.

The shelf life of your mayonnaise will vary depending on if it is homemade or purchased at the store. According to Dr. Karen Latimer, a store-bought bottle of mayonnaise can last many months when unopened and kept out of the sun, as the store-bought version contains preservatives that allow for longer shelf-life.
Only one week is shorter than the store-bought shelf-life of mayonnaise, because homemade mayonnaise contains no preservatives. Store-bought, unopened mayonnaise may keep in the refrigerator for a pretty long time, while a homemade mayonnaise will only last very short. Making a batch also requires little thought, and mayo can last for up to two weeks refrigerated.
A good rule of thumb is that the mayo will last covered in the refrigerator up to one week, but you might find that it will last a bit longer depending on how fresh the eggs are. Before the mayo can open, the jar can stay refrigerated about three months, or until expiration. Most recipes of homemade mayonnaise typically last 2-4 days if kept in the fridge before quality decreases or becomes unsafe to eat.
Homemade mayo has a higher risk of spoilage than those made at the store, since the latter is loaded with preservatives which may kill off harmful bacteria such as Salmonella. Homemade mayo contains raw eggs, which are safe to eat in moderation if kept under proper conditions. You can use sterilized mixing equipment and pasteurize the yolks of the eggs to make a homemade mayo with longer shelf life, but it is still safe to make only a couple of days.
Once you are done tweaking acidity, simply make sure you let the homemade mayo sit out of the refrigerator for some time before adding to your container and placing in the freezer. That is, if you are adding more vinegar and increasing acidity, homemade mayo should keep for a lot longer — about 2-4 weeks, on average. If you would like to prolong it further, you will have to add a preservative like vinegar or lemon juice.
Depending on how much mayo you use at home, preparing a 1/2 cup mayo can be a daily occurrence, or it can be enough to get you through the whole 2 week shelf life. For example, you could make potato salad, macaroni salad, tuna salad, egg salad, or even pizza sauce with homemade mayo. Not only do you get a mayo that is impossibly smooth and velvety, you are also able to tailor it to your tastes or to specific recipes.
Making your own mayonnaise batches allows you to enjoy this wonderful-tasting condiment free from the preservatives and additives found in store-bought mayonnaise.

You can make homemade mayonnaise without mustard, but keep in mind mustard is one of the fail-safes that we added to this homemade mayonnaise recipe in order to promote emulsification. Along with the simple yolk, mustard helps to emulsify the mixture, which lowers your risk of breaking mayonnaise.
If you are going to use 2 yolks rather than 1 whole egg and 1 egg yolk, and cut down on vinegar to 1 teaspoon rather than 2, then your mayonnaise will be thicker, all else being equal. Yes, but remember, there is a fair amount of oil required for this recipe for homemade mayonnaise, so strong or strong-flavored oil will give your mayonnaise more strength of flavor. I have also tried using lighter olive oil since the recipe was written, and as this made a fabulous mayo that tastes better than any store bought one I have had, I stopped there.
I have no idea what shelf-life is for this type of mayo, but if that does not provide you with the desired duration, I doubt that there is any other way of making it last, other than perhaps using pasteurized eggs. If you notice your mayonnaise is splitting up, with the liquid pooling at the top, then it is time to toss it. When your mayonnaise starts smelling really acidic or sour, you know it is no longer safe to eat.
Add 1 tbsp whey to your mayonnaise, stir well, and let it sit out at room temperature for 6 hours. By doing these things, you should be able to get another week or two of use out of your mayonnaise. While that does not seem like much time, the average homemade mayo recipe takes just about 15 minutes to make, and only requires a few ingredients.
