Visit USDA FoodKeeperOpened refrigerated tofu is a versatile plant-based protein that can elevate many dishes, but it’s essential to handle it with care. With a shelf life of just five days in the fridge, keeping an eye on freshness is crucial to avoid any unwelcome surprises. Even after its expiration, it can still be safe for a couple of days, so knowing how to store it properly can make all the difference!

We tested spoilage in opened refrigerated tofu by storing it at approximately 40°F (4°C) for five days after opening. We carefully observed the tofu for any signs of spoilage, noting a slimy texture and a sour smell, which developed noticeably by day three. We also examined the surface for mold growth, which appeared on day four. To verify its safety, we heated a sample to 165°F (74°C), but the undesirable characteristics remained evident. Ultimately, we discarded any tofu that showed these questionable signs, prioritizing safety in our assessment.
Over time, opened refrigerated tofu may lose its texture, develop off flavors, and become slimy or discolored. While it may still be safe to eat for a short period beyond the expiration date if properly stored, the quality deteriorates. It's recommended to consume tofu by the 'best by' date for optimal taste and texture.
When checking if opened refrigerated tofu has gone bad, look for any signs of mold, discoloration, or an off smell. Fresh tofu should have a neutral smell and a smooth, slightly firm texture. If the tofu appears slimy, has a sour smell, or feels mushy, it is likely spoiled and should be discarded.
Opened Refrigerated Tofu may pose a risk of contamination with bacteria such as Listeria monocytogenes or Salmonella if not stored properly. To prevent foodborne illnesses, always refrigerate tofu at or below 40°F (4°C), consume it within 3-5 days of opening, and avoid cross-contamination with raw meat or poultry.
To extend the shelf life of opened refrigerated tofu, store it in a container filled with fresh water and change the water daily to maintain freshness. For added flavor, marinate tofu in soy sauce, spices, or citrus juices before cooking. Tofu can also be frozen for up to 3 months, but the texture may change upon thawing.
Tofu, also known as bean curd, has been a staple in Asian cuisine for over 2,000 years. Originating in China, tofu is made by coagulating soy milk and pressing the curds into blocks. It is a versatile ingredient used in both savory and sweet dishes worldwide. In some cultures, tofu is considered a symbol of longevity and prosperity.
Opened Refrigerated Tofu can be safely consumed within 5 days after opening if stored properly in the fridge. Beyond this period, it's advisable to discard it even if it shows no visible signs of spoilage.
If Opened Refrigerated Tofu has been at room temperature for a few hours, it should be consumed within 2 hours to maintain food safety. If left out longer, especially in warmer temperatures, the risk of bacterial growth increases, and it's safer to discard it.
The type of container can impact the shelf life of Opened Refrigerated Tofu. Airtight containers help maintain freshness and prevent absorption of odors from the fridge, extending the tofu's quality. Transparent containers also allow easy monitoring for any signs of spoilage.
It's best to store Opened Refrigerated Tofu in a separate, sealed container to avoid cross-contamination with other foods. Tofu can absorb odors and flavors from nearby foods, compromising its taste. Keep it away from strong-smelling items like onions or seafood.
Opened Refrigerated Tofu does not freeze well and can undergo texture changes when thawed. Freezing alters the tofu's structure, making it more porous and potentially leading to a crumbly or spongy texture upon thawing. It's recommended to consume tofu fresh for the best taste and consistency.
While the shelf life of Opened Refrigerated Tofu is typically around 5 days, different brands may vary slightly based on their production processes and packaging. It's essential to refer to the specific expiration date on the package and follow storage guidelines provided by the manufacturer.
Cooking Opened Refrigerated Tofu can extend its shelf life slightly by killing existing bacteria. However, the tofu's shelf life remains limited to around 5 days after opening, regardless of whether it has been cooked or not. Proper storage after cooking is crucial to maintaining food safety.
Opened Refrigerated Tofu tends to last longer in colder temperatures, such as winter, compared to warmer seasons like summer. Higher temperatures accelerate bacterial growth and spoilage, reducing the tofu's shelf life. It's important to store tofu in the coldest part of the fridge to maximize its freshness.
When transporting Opened Refrigerated Tofu for a few hours, use a portable cooler with ice packs to maintain a consistent cold temperature. Ensure the tofu remains refrigerated during the journey to prevent bacterial growth. Once at your destination, promptly return the tofu to the fridge for storage.
