Tempeh is one of the most popular food ingredients, loved for its savory taste, high nutritional value, and versatility in various dishes. However, since it’s made from soybeans and goes through a fermentation process, tempeh is quite prone to spoilage if not stored properly. Spoiled tempeh is definitely not safe to eat and can lead to digestive issues. So, to help you stay cautious before cooking or preparing tempeh, it’s really important to recognize the signs of spoiled tempeh. Let’s take a closer look at them below! 

Signs of Spoiled Tempeh 

Here are several signs you can look for to identify when tempeh is no longer safe to consume: 

1. Color Changes 

Fresh tempeh typically has a pale white color due to the growth of healthy Rhizopus mold. But when tempeh starts to spoil, this color begins to change. You might notice it turning grayish, brownish, or even black. In some cases, the white mold may disappear or appear uneven. These color changes are one of the earliest and most visible signs of spoilage. 

2. Unpleasant Odor 

Fresh tempeh usually has a slightly sweet aroma from the fermentation process. However, once it goes bad, the smell becomes sharp, sour, or even rotten. If you notice a strong, unpleasant odor when opening the packaging, it’s best not to use the tempeh. 

3. Slimy or Mushy Texture 

Another sign is a change in texture. Spoiled tempeh often feels soft, wet, or even slimy. This can be caused by over-fermentation or the growth of unwanted microorganisms. It’s very different from the firm and dry texture of fresh tempeh. 

4. Sour or Bitter Taste 

If you happen to taste it, although it’s not recommended if the tempeh already seems suspicious, spoiled tempeh usually tastes sharply sour or bitter, far from the signature savory flavor of fresh tempeh. This is a clear sign that it’s no longer suitable for consumption. 

5. Appearance of Other Molds 

The mold that should grow on tempeh is white. But when tempeh is spoiled, other molds such as black or brown spots often appear. This indicates contamination by other microorganisms that may be harmful to your health. 

6. Tempeh Falls Apart Easily 

Another sign of spoiled tempeh is that it crumbles easily when sliced or cooked. Fresh tempeh generally has a compact structure, making it firm and easy to cut without falling apart.

Tips for Storing Tempeh to Prevent Spoilage 

To make tempeh last longer, it’s best to store it in the refrigerator, either in the chiller or freezer. If stored at room temperature, it should ideally be cooked within 1–2 days after purchase. Wrap the tempeh in paper or perforated plastic to allow air circulation and prevent excess moisture.
