Does Tempeh Go Out Of Date?

Tempeh is a fermented soybean product that is commonly used in Asian cuisine. It is made from cooked whole soybeans that have been inoculated with Rhizopus oligosporus (a fungus). The fermentation process causes the beans to swell and become firmer. It also produces beneficial enzymes and amino acids.

The Benefits of Tempeh

Tempeh is a great food that provides more protein than tofu, and it has many different uses. It is rich in vitamins B12 and other essential nutrients like iron, which you can’t get from any other source. Tempeh also has fewer calories, so enjoy this healthy meal while being good for your health!

The Risks of Tempeh

Although tempeh is generally safe to eat, there are some risks associated with consuming it. These include allergies and intolerances, such as lactose intolerance. Also, if you consume too much tempeh, it can cause flatulence.


While tempeh is generally considered to be safe to eat, it should be avoided by those who suffer from certain health conditions. However, even though tempeh is not suitable for everyone, it is still nutritious and versatile food.

How Long Does Opened Tempeh Last?

Once opened, tempeh should keep well in an airtight container in the refrigerator for about five days.

However, if you want to extend its shelf life even further, you can freeze the tempeh. To do so, place the frozen tempeh in a freezer bag and store it in the freezer for up to six months.

When thawed, the tempeh will need to be cooked before using.


Tempeh can be stored in the refrigerator for several weeks, but it is best to use it within three to four days after opening.

Freezing tempeh extends its shelf life significantly, allowing you to enjoy it for much longer than just a few days.

How can you tell if tempeh has gone bad?

When purchasing tempeh, check the expiration date on the package. If the tempeh looks dry and crumbly, it has probably expired.

How Can You Tell If Tempeh Has Gone Bad?

Tempeh is a great source of protein, fiber, and B vitamins. However, because it is a fermented food, it does not last forever. Once tempeh goes bad, it loses its texture and flavor.

To test if tempeh has spoiled, simply cut off a small piece and place it under running water. If it smells sour or tastes bitter, it has likely gone bad.


If you buy tempeh that has an expiration date on it, you should use it within the time. If you do not plan on using it right away, store it in the refrigerator so that it stays fresh longer.

Why Does Tempeh Go Bad So Quickly?

Tempeh is made from fermented soybeans. When it is stored properly, tempeh can last for several months without spoiling. Unfortunately, most stores sell tempeh that is packaged in plastic bags with airtight lids. These types of containers allow oxygen to enter the package, which causes the tempeh to quickly go bad.

What Should You Do If You Notice Signs of Spoilage?

If you see any signs of spoilage, such as mold or discoloration, you should throw out the entire container of tempeh. The best thing to do is to buy fresh tempeh instead. If you cannot find fresh tempeh, you can freeze it. Once frozen, you can thaw the tempeh and use it within one month.


While tempeh can go stale quickly, there are ways to extend its shelf life. Make sure to purchase fresh tempeh whenever possible, and keep it refrigerated when storing.
