Tofu is an extremely perishable food and should be stored properly. If not, it can contaminate other foods. However, this does not mean that tofu should be discarded if it goes bad. It can be stored in the freezer for months or years after its expiration date.
If you are unsure how long tofu lasts, you can always check the package. Some brands have a best-by date on the box. This is a good indicator of how good the tofu is when purchased. Aside from its use-by date, the shelf life of tofu depends on several factors. The storage methods will also impact how long it lasts.
What is Tofu?
Bean curd, sometimes referred to as tofu, is a popular soybean-based cuisine frequently used in vegetarian and vegan meals instead of meat. Although tofu is typically eaten cooked, it can also be eaten uncooked.
Tofu often has a nutty or bean-like flavor and is mushy and crumbly. It can be crumbled or diced and added to salads or other recipes as a protein-rich component. Additionally, tofu can be consumed raw as a snack, on its own, or with a dip or sauce.
Tofu may have a softer texture and be better suited for eating raw than tofu with a firmer texture. This is especially true with tofu branded “silken” or “soft.”
How Long does Tofu Last in the Fridge?
It’s crucial to remember that tofu will taste better the fresher it is. When kept in a refrigerator, tofu normally stays for 1-2 weeks if properly maintained in an airtight container or resealable bag. Additionally, tofu can be frozen for up to six months, which can lengthen its shelf life. When thawed, it will, however, alter the tofu’s texture.
Ideally, tofu should be refrigerated. Refrigerated tofu will last for up to three to five days. After this time, the quality of the tofu will start to decline.
On the other hand, shelf-stable tofu is a type of tofu that does not need refrigeration. Instead, it can be kept at room temperature or in a cool, dark area. Usually, the tofu is packaged in an aseptic carton and should be stored in a tightly sealed container.
How to Freeze Tofu?
The following is the proper way to freeze tofu:
- Blot the tofu: The tofu can be pressed to remove extra water or wrapped in a fresh kitchen towel for about 15 minutes with a heavyweight.
- Tofu should be cut into appropriate pieces. Slice, cut, or otherwise shape the tofu as you like.
- Blanch the tofu: Although this step is optional, it is advised because it helps the tofu become firmer and keeps it from crumbling too much after thawing. The tofu should be brought to a boil for a few minutes, then immediately placed in a bowl of ice water to chill.
- Tofu should be dried by patting it with a fresh kitchen towel or several paper towels.
- Wrap the tofu: On a baking sheet covered with parchment paper, arrange the pieces in a single layer and freeze for at least two hours. Once the tofu has frozen, move it to an airtight container or freezer bag and squeeze out as much air as possible. Within six months, use.
Note: When thawed, frozen tofu may release some water, change somewhat in texture from fresh tofu, and become slightly porous and spongy.
What is the Taste of Tofu?
Depending on how it is prepared, tofu’s flavor and texture can change and be used in both savory and sweet dishes. It takes on the characteristics of the other ingredients it is cooked with and has a mild, slightly nutty, or bean-like flavor. For example, silken or soft tofu has a smoother, more delicate texture and a milder flavor than firm or extra-firm tofu, which has a tougher, more meat-like texture and a slightly stronger flavor.
In addition to grilling, stir-frying, and roasting, tofu may be cooked in various ways and taste good when combined with savory ingredients and sauces. While some find tofu’s flavor unappealing or boring, others enjoy its delicate flavor. Marinating tofu before cooking is a good way to enhance its flavor.
How to Store Tofu?
In the freezer or refrigerator, tofu can be kept.
Storage for refrigerators:
- Tofu should be drained by pressing it or wrapping it in a fresh kitchen towel and pressing it for about 15 minutes with a heavy object.
- Put the tofu in a sealable bag or an airtight container.
- For one to two weeks, place the tofu in the refrigerator.
- Before using it, check the tofu for any signs of spoilage, such as a sour smell or a slimy texture.

Is Tofu Free of Gluten?
Because it is made from soybeans, which don’t contain gluten, it is naturally gluten-free.
But it’s important to remember that some tofu may be prepared or processed in facilities that also handle cereals containing gluten, like rye, wheat, and barley. Make sure the tofu you buy is labeled “gluten-free” if you have celiac disease or a gluten allergy.
Notably, some tofu may be cooked or spiced with ingredients that contain gluten, like soy sauce or broth made from wheat. If you are gluten-free, check the ingredient list of flavored or seasoned tofu products to ensure they don’t contain gluten.
For people following a gluten-free diet, tofu is typically a safe and wholesome food as long as it is carefully acquired and prepared. It contains some essential components, such as calcium, iron, and B vitamins, and is a good source of plant-based protein.
How should you Eat Tofu for Health Benefits?
Tofu is a nutritious food that can be used in many different ways in a balanced diet. Here are some wholesome recommendations for making and eating tofu:
Choose the right kind of tofu: The textures of tofu range from silken to soft to firm to extra-firm. Generally speaking, firmer tofu has less moisture and, because it has undergone less processing, may be slightly more nutrient-dense than more delicate types. Your choice will rely on the dish and your personal preferences.
Tofu can be seasoned or marinated to add taste. Herbs, spices, and other savory ingredients can strengthen or marinate tofu. This can improve the flavor of the tofu and boost the nutritional content of your meals.
Try out several cooking techniques: Among other cooking methods, tofu can be grilled, stir-fried, roasted, or baked. To enhance the flavor and nutritional value of your food, think about using a variety of healthy oils, like coconut oil and olive oil.
How to Identify Whether Tofu is Bad?
Fresh tofu should have a consistent, smooth texture. If you see any discoloration, such as brown or grey spots, or if it feels slimy, the tofu may have gone rotten. The following are a few signs that tofu might not be good:
- The aroma of fresh tofu should be nice and nutty. Odors overpowering, sour, or rotting suggest that the tofu may be damaged.
- Taste: Tofu with an off, rotting, or strange flavor should be discarded.
- Expiry date: Look at the expiration date on the packaging; if the tofu is past the date, it should be discarded.
It’s critical to remember that eating spoiled tofu can result in sickness. Always err on caution, and if you believe the tofu has gone bad, dump it.
What are the Side Effects of Consuming Bad Tofu?
There are a few hazards to consider if you wish to include raw tofu in your diet, even though it can be a wholesome and nutritious dish. Here are a few instances:
- Contamination: If tofu is not handled and stored properly, it could become contaminated with bacteria, viruses, or other hazardous things, just like any other food. Always wash your hands before handling tofu, and store it in the refrigerator until you’re ready to use it to lower the chance of contracting a foodborne disease.
- Toxins: Trypsin inhibitors and lectins, which can interfere with digestion and be dangerous if ingested in high quantities, can be found in raw soybeans, especially raw tofu. Tofu is generally safe to eat in moderation because these chemicals are typically eliminated during processing.
- The cooking method might also change the number of nutrients available in tofu. For instance, cooking tofu can improve iron availability, which is important for delivering oxygen to the body’s cells. According to several research, tofu’s calcium is more easily absorbed when ingested raw.
Overall, it’s important to consider the advantages and disadvantages of consuming raw tofu before deciding if it’s right for you. It’s always a good idea to handle and store tofu properly, just like any other food, to lower the chance of contracting a foodborne illness.
Reference: Soy, Tofu and Brain Function in the Elderly
Some consider tofu a “superfood,” and intake of it, which is common in Asia and growing in the West, is said to provide a host of health benefits. Studies on animals and in cell cultures suggest that phytoestrogens, which are prevalent in soy products like tempeh and tofu, might shield the aging brain. These results must be confirmed in humans because dementia prevalence increases as the population ages. According to some observational studies (Kreijkamp-Kaspers et al. 2007; Franco et al. 2005), consuming phytoestrogens has no negative effects on cognitive function. However, these findings were mostly found in populations with low intake.
Conclusion
Tofu is considered to be a healthy food. It is a vegetarian meat substitute that offers good amounts of protein. Tofu is often paired with other nutritious foods such as fruits, veggies, and whole grains. The best way to avoid spoilage is to store tofu in a cool place. Tofu left out at room temperature for a long period can get slimy and start to form mold.
Tofu can last up to three months in the freezer. If you have purchased the shelf-stable kind, it can last even longer. However, tofu can also go bad quickly when left at room temperature. When tofu is not stored properly, it can turn brown or taste sour. It is a good idea to replace tofu that has gone bad with fresh tofu before it gets stale.
