How Long Does Vegan Mayo Last?

Vegan mayo, whether opened or unopened, has varying shelf lives depending on factors like ingredients, manufacturing, and storage conditions.

How to Tell if Vegan Mayo Has Gone Bad

To determine if vegan mayo has gone bad, you can rely on your senses and a visual inspection. Here are some signs that tell you whether your vegan mayo is bad:

  1. Smell: Fresh vegan mayo should have a light, tangy scent. If it starts to emit a sour or rancid odor, it’s a clear sign that it has spoiled, and you should discard it.
  2. Visual Inspection: Examine the container for any signs of mold growth or unusual colors. If you notice any mold spots or if the mayo has developed an off-color, it’s best not to use it.
  3. Texture: Vegan mayo should have a smooth, creamy texture. If you open the container and find that the texture is lumpy or if there’s a noticeable separation of liquids and solids, it’s an indication that the mayo has likely gone bad.

You can tell if vegan mayonnaise is bad by checking for an off smell, like a rancid or sour odor; mold or discoloration, such as dark spots or unusual colorings; and an altered texture, like excessive thickness or separation. Be sure to check the expiration date on the packaging.
