Common Signs of Spoiled Tofu

Unusual Odor

One of the most common signs that your tofu has gone bad is a strong and unusual odor. Fresh tofu should have a mild, slightly sweet smell. If you notice a sour or pungent odor coming from your tofu, it is likely spoiled and should be discarded.

Mold Growth

Another clear indicator that your tofu is no longer safe to eat is the presence of mold growth. If you see any green, black, or white spots on the surface of your tofu, it is best to throw it away immediately. Consuming moldy tofu can lead to food poisoning and other health risks.

Slimy Texture

Fresh tofu has a firm and slightly spongy texture. If you find that your tofu has become slimy or slippery to the touch, it is a sign that it has spoiled. The slimy texture is often accompanied by a sour smell, indicating that harmful bacteria have started to grow on the tofu. It is best to err on the side of caution and discard any tofu that has developed this texture.

How to Properly Store Tofu


When storing tofu in the refrigerator, it is important to keep it in its original packaging or transfer it to an airtight container filled with water. Change the water every day to keep the tofu fresh. Tofu can typically last in the refrigerator for up to one week.


If you have a surplus of tofu that you want to store for a longer period of time, freezing is a great option. Drain the tofu, wrap it in plastic wrap, and place it in a freezer-safe bag. Frozen tofu can last for up to three months. When ready to use, simply thaw it in the refrigerator overnight.


When purchasing tofu, make sure to check the expiration date on the packaging. It is best to choose tofu that is vacuum-sealed or in a tightly sealed container to ensure freshness. Once opened, be sure to store any leftover tofu properly to prevent spoilage.

Tips for Preventing Tofu Spoilage

Use By Date

Always check the expiration date on the packaging before purchasing tofu. Make sure to consume the tofu before the use by date to ensure its freshness and quality.

Proper Sealing

After opening the tofu packaging, make sure to store any unused portions properly. Transfer the tofu to an airtight container filled with water and keep it refrigerated. Change the water every day to maintain freshness.

Avoiding Cross Contamination

To prevent tofu from spoiling prematurely, avoid cross contamination with other foods in the refrigerator. Store tofu away from strong-smelling foods and make sure to use separate cutting boards and utensils when preparing tofu dishes.

In conclusion, it is important to be able to recognize the signs of spoiled tofu in order to avoid any potential health risks. By checking for changes in color, texture, and smell, you can ensure that you are consuming tofu that is safe and fresh. Remember to always store tofu properly in the refrigerator and to consume it within a reasonable timeframe. If you have any doubts about the quality of your tofu, it is always better to err on the side of caution and discard it. Your health and well-being are worth the extra effort to ensure that your tofu is not bad.
