Tofu, a high-protein food with low cholesterol and calorie content, is a staple in many vegan and vegetarian diets. This soy-based food is made by curdling and pressing soybeans into blocks, which are then used in a wide range of recipes. Tofu can be consumed plain or used as an ingredient in soups, stir-fries, and salads. It is also a versatile ingredient that can be grilled, baked, or fried to add flavor and texture to dishes. Given that tofu is primarily composed of soybeans and water, it is an excellent source of protein and a popular alternative to meat for those following a plant-based diet.
How long does tofu last?
|Shelf-stable tofu (unopened)||Best-by + 1 – 2 weeks|
|Shelf-stable tofu (opened)||4 – 5 days|
|Refrigerated tofu (unopened)||Use-by + 3 – 7 days|
|Refrigerated tofu (opened)||4 days|
|Cooked Tofu||4 days|
An opened block of tofu can last up to 4-5 days in the refrigerator due to exposure to air, leading to bacterial growth on its surface. Conversely, an unopened block of tofu can last from 6 months to 1 year. To prolong the shelf life of unopened tofu, freezing it is a viable option, allowing it to stay fresh for approximately 1 year. To further extend the shelf life of tofu, utilizing a vacuum-sealed container or bag can prevent air exposure and reduce the growth of bacteria. This is particularly beneficial for those who want to keep their tofu fresh for an extended period. As tofu is a versatile ingredient in many dishes, it’s essential to be mindful of its shelf life and storage to ensure its freshness and prevent food waste.
How long does cooked tofu last?
When tofu is cooked, it can last for up to 4 days in the refrigerator. To extend its shelf life further, it is possible to freeze it. Freezing tofu can be a useful solution when there is leftover tofu that cannot be consumed within the 4-day timeframe. It is important to note that freezing tofu can alter its texture, causing it to become harder. This may not be preferable for some dishes where a soft texture is desired. However, frozen tofu can be a great addition to soups and stews, where texture is less of a concern. When preparing to freeze cooked tofu, it is best to wrap it tightly in plastic wrap or aluminum foil, ensuring that it is well-sealed to prevent freezer burn. By following these guidelines, it is possible to keep cooked tofu fresh for a more extended period, allowing it to be enjoyed in future meals.
How to know if tofu is bad?
Determining whether tofu has gone bad can be done by utilizing a few simple tips. One of the most apparent signs of spoilage is if the tofu has an off-putting smell, particularly if it has a sour or rotten odor. Additionally, visual cues such as mold or discoloration on the surface of the tofu can indicate that it has gone bad. Touch is also an effective way to determine whether tofu is still fresh. If the tofu feels slimy or has a mushy texture, it may be an indication that it has spoiled. By using these methods to assess the condition of tofu, it is possible to ensure that it is safe for consumption and avoid any potential health risks that could arise from consuming spoiled food.
Presence of Mold:
One of the most noticeable signs of spoilage in tofu is the presence of mold. When tofu is exposed to air, it can spoil quickly and develop mold on its surface. If mold is present on the tofu, it is an indication that it has gone bad, and it should be discarded immediately. Mold growth can be identified by visible dark spots or discoloration on the surface of the tofu. In such instances, it is essential to dispose of the tofu to prevent any potential health hazards that could arise from consuming spoiled food. By being vigilant and checking for the presence of mold, individuals can ensure that they are consuming fresh and safe-to-eat tofu.
One way to detect spoilage in tofu is to utilize the sense of smell. If tofu has gone bad, it will emit a sour odor that can be easily identifiable. Consuming tofu that smells sour is not recommended, as it can lead to food poisoning and potential health risks. It is important to note that this sour odor can be quite potent, so it is advisable to discard the tofu immediately and not attempt to salvage it for consumption. By using the sense of smell to detect spoilage in tofu, individuals can take the necessary precautions to prevent any adverse health effects that could arise from consuming spoiled food.
An additional method for detecting spoilage in tofu is to observe any changes in its color. Fresh tofu typically has a white color, but when it spoils, it can develop a yellow or greenish tinge, indicating that it is no longer safe for consumption. Any discoloration on the surface of the tofu is a clear sign that it has gone bad, and it should be discarded immediately. It is crucial to note that the presence of discoloration, particularly in conjunction with other signs of spoilage such as an off-putting odor or mold growth, can be a strong indication that the tofu is not safe to consume. By being attentive to any color changes in tofu, individuals can take the necessary precautions to avoid consuming spoiled food and minimize the risk of potential health hazards.
In cases where there is uncertainty about the spoilage of tofu, an additional method for detecting spoilage is to taste a small portion of it. If the tofu has gone bad, it will have a sour or bitter taste, indicating that it is no longer safe for consumption. However, it is not recommended to taste tofu that appears to have gone bad since consuming spoiled food can cause food poisoning and other health risks. Thus, it is advisable to err on the side of caution and dispose of the tofu if any signs of spoilage are detected, such as mold growth, discoloration, or a sour odor. By being aware of these signs and taking appropriate actions to dispose of spoiled tofu, individuals can minimize the risk of potential health hazards associated with consuming spoiled food.
How to store tofu properly?

Is it Okay to eat expired tofu?
Consuming tofu past its expiration date is generally safe, provided that it has been stored correctly, and there are no indications of spoilage. The expiration date on tofu packages indicates when the tofu is expected to be at its best quality and flavor, but it does not necessarily indicate that it will be harmful to consume after that date. As long as there are no signs of spoilage such as mold growth, discoloration, or a sour odor, and the tofu has been stored appropriately in the fridge or freezer, it should be safe to consume beyond its expiration date. However, it is always recommended to exercise caution when consuming any food item that has passed its expiration date, as there is a possibility of it being spoiled and posing a risk to one’s health.
