Introduction to Tofu
Before we dive into the specifics of how long tofu can last in the fridge, it's important to understand what tofu is and its nutritional value.
What is Tofu?
Tofu, also known as bean curd, is a versatile food product made from soy milk. The soy milk is curdled and then pressed into soft white blocks. Originating from China, tofu has been a staple in Asian cuisines for over 2,000 years and is now enjoyed worldwide for its high protein content and adaptability to various cooking methods and flavors.
Nutritional Value of Tofu
Tofu is not just versatile in the kitchen, it's also packed with nutritional benefits. It's a great source of protein, especially for vegetarians and vegans. Tofu contains all nine essential amino acids, making it a complete protein source.
In addition to protein, tofu is a good source of iron and calcium, and it also contains magnesium, copper, zinc, and vitamin B1. Plus, tofu is low in calories and relatively low in fat, making it a healthy choice for those watching their calorie intake.

Understanding what tofu is and its nutritional value is the first step in knowing how to properly store it in the fridge. In the following sections, we'll provide you with the information you need to maximize the lifespan of your tofu. Whether you're a tofu veteran or a newbie, you'll find useful tips and insights on how to store and preserve this nutritious food.
Storing Tofu in the Fridge
Ensuring that your tofu stays fresh for as long as possible begins with proper storage in your refrigerator. This section will guide you through the correct techniques for storing tofu and how to identify signs of spoilage.
Proper Storage Techniques
To maximize how long tofu lasts in the fridge, you need to follow a few essential steps. Tofu comes in a package filled with water, which helps to preserve its freshness. Once opened, any unused tofu should be stored in a clean airtight container submerged in cold water. The water should be changed daily to keep the tofu fresh.
If you notice a slight bitter smell or sour taste when changing the water, don't worry! This is normal and does not mean the tofu is spoiled. Once the tofu is rinsed and the water is refreshed, these flavors should disappear.

Signs of Spoiled Tofu
When it comes to knowing whether your tofu has gone bad, rely on your senses. The first sign of spoilage is a change in smell. Fresh tofu has a mild scent. If your tofu begins to smell sour, pungent, or off-putting, it likely has gone bad.
Next, check the tofu's appearance. Fresh tofu is typically white or off-white. If your tofu has developed a yellow or brown hue or has visible mold, it's time to throw it out.
Finally, the texture of tofu can also indicate whether it has spoiled. Fresh tofu has a firm yet soft texture. If your tofu feels slimy or excessively hard, it's best not to consume it.

It's important to remember that consuming spoiled tofu can lead to foodborne illness, so when in doubt, throw it out. For more information on food storage times, check out our articles on how long cooked salmon can stay in the fridge or how long do grapes last in the fridge.
Tofu's Lifespan in the Fridge
Knowing how long tofu lasts in the fridge is crucial for food safety and preventing waste. The lifespan of tofu in the fridge depends on the type of tofu and its condition when you store it.
Fresh tofu, often sold in bulk at health food stores or Asian markets, should be consumed within two to three days. It's important to change the water in which the tofu is stored daily to maintain its freshness. If you see any signs of mold or detect an off smell, discard the tofu immediately.

Extending the Shelf-life of Tofu
Given the perishable nature of tofu, you might often wonder, "how long does tofu last in the fridge?" While the answer depends on various factors such as the freshness of the tofu and the storage method, there are ways to extend its shelf-life. Two effective methods are freezing and marinating.
Storing tofu in the freezer can significantly extend its lifespan. When you freeze tofu, the water inside the tofu forms ice crystals. This process changes the texture of the tofu, making it firmer and more absorbent. As a result, frozen tofu can better absorb marinades and sauces, enhancing its flavor.
To freeze tofu, follow these steps:
- Drain the tofu: Remove the tofu from its package and drain off any excess liquid.
- Slice the tofu: Cut the tofu into slices or cubes, depending on your preference. Smaller pieces will freeze quicker and thaw more evenly.
- Lay out the tofu: Spread the tofu pieces on a baking sheet lined with parchment paper. Make sure the pieces are not touching, so they don't freeze together.
- Freeze the tofu: Place the baking sheet in the freezer and leave it until the tofu pieces are completely frozen.
- Store the tofu: Once frozen, transfer the tofu pieces into a freezer-safe bag or container. Make sure to remove as much air as possible before sealing to prevent freezer burn.
Frozen tofu can last up to three months. When you're ready to use it, let it thaw in the refrigerator overnight, then press it to remove any excess water before cooking.
Marinating tofu not only enhances its flavor but can also extend its life in the refrigerator. The marinade acts as a preservative, slowing down the spoiling process.
To marinate tofu, follow these steps:
- Drain and press the tofu: Remove the tofu from its package, drain off the excess liquid, and press it to get rid of any remaining water.
- Prepare the marinade: Mix together your choice of marinade. This could include ingredients like soy sauce, vinegar, garlic, ginger, and spices.
- Marinate the tofu: Place the tofu in a shallow dish or a zip-top bag and pour the marinade over it. Make sure all the tofu pieces are covered in the marinade.
- Refrigerate the tofu: Put the tofu in the refrigerator and let it marinate for at least 30 minutes, though longer is better for more flavor absorption.
Marinated tofu can last up to a week in the refrigerator. Remember to store it in an airtight container to prevent it from drying out.
By freezing or marinating your tofu, you can extend its shelf-life and enjoy it for longer. These methods also offer an opportunity to enhance the flavor of tofu, making it even more enjoyable.

Safety Tips for Consuming Tofu
As with any food, tofu must be handled properly to ensure its safety and quality. Improper storage and consumption of tofu can lead to health risks, and knowing the best practices for handling tofu will help maximize its lifespan in your fridge.
Health Risks of Spoiled Tofu
Spoiled tofu can pose health risks, mainly due to the growth of harmful bacteria. Consuming spoiled tofu can lead to food poisoning, resulting in symptoms like nausea, stomach cramps, vomiting, and diarrhea.
To avoid these health issues, it's essential to know how long tofu lasts in the fridge and to recognize the signs of spoilage. Signs of spoiled tofu include a change in color, an off smell, and a slimy texture. If you notice any of these signs, discard the tofu immediately.
Best Practices for Handling Tofu
Proper handling and storage of tofu can extend its shelf life and ensure its safety for consumption. Here are some best practices for handling tofu:
- Check the expiration date: Always check the expiration date on the packaging before buying or consuming tofu.
- Store properly: After opening, keep the remaining tofu submerged in water in a container with a tight lid. Change the water daily to keep the tofu fresh.
- Refrigerate: Always store your tofu in the refrigerator to slow down the growth of bacteria.
- Observe changes: Be mindful of any changes in the tofu's color, smell, or texture. If anything seems off, it's safer to discard the tofu.
Remember, the key to answering 'how long does tofu last in the fridge' lies in proper storage and handling. Just like how we handle how long does cooked meat last in the fridge or how long does spaghetti last in the fridge, tofu also requires the same level of care. By following these guidelines, you can enjoy your tofu safely and make the most of its nutritional benefits.
