Proper storage of tofu will protect it from spoiled flavor, color, or texture. Proactively manage the best before and expired dates to avoid accidental consumption of expired tofu.
Understanding the Basics of Tofu
Tofu is a great source of protein, and it has become increasingly popular due to its versatility and health benefits. But it’s important to understand the basics before deciding to cook with tofu. This includes understanding what tofu is, what types are available, and most importantly, how to properly store tofu.
In this article, we’ll go over the basics of tofu, starting with how to store unopened tofu in the fridge.
What is Tofu?
Tofu, or bean curd, is a plant-based protein made from soybeans. Its basic form has a bland taste and spongy texture, making it an excellent ingredient for various dishes.
To make tofu, soybeans are soaked, ground and boiled in water, producing a milk-like substance known as soy milk. The soy milk is then curdled using a coagulant, like calcium sulfate or magnesium chloride, which separates the curds from the whey. The curds are then pressed into solid blocks that can be cut into different shapes, sizes, and textures.
Unopened tofu can last several months in the fridge past its expiration date. However, the storage time of tofu greatly depends on its manufacturer, processing method, and packaging. Upon opening, tofu needs to be consumed within 3-5 days, or it can be frozen for up to five months to extend its shelf life. Pro tip: Always check the expiration date on tofu packaging and observe the storage instructions thoroughly.
Different Types of Tofu
Tofu, or bean curd, is a highly versatile and popular food made from condensed soy milk. Different types of tofu are available in the market, each with its unique texture and flavor profile.
Silken Tofu – This type of tofu has a smooth and delicate texture, almost like custard. Therefore, it is ideal for making desserts, smoothies, and sauces.
Soft Tofu – Soft tofu is creamier and has a slightly firmer texture than silken tofu. It is best used in soups, stews, and curries.
Firm Tofu – Firm tofu has a dense and meaty texture, making it ideal for grilling, frying, and stir-frying. It is also suitable for making vegan meat substitutes.
Extra-Firm Tofu – As the name suggests, extra-firm tofu has a very dense and chewy texture. Therefore, it is the best option for baking, grilling, and pan-frying.
When it comes to storing tofu, unopened packages can last for up to five months in the fridge. However, once opened, tofu should be consumed within seven days for best quality. Pro Tip: To prolong the shelf-life of opened tofu, store it in a container filled with water and change it daily.

How Long Does Unopened Tofu Last in the Fridge
Tofu is a versatile food that can be used in various recipes. It’s also a great source of plant-based protein for vegetarians and vegans. But how long does unopened tofu last in the fridge? Proper storage and handling are necessary to get the most out of it. So let’s explore what you need to know about storing tofu.
Factors Affecting Shelf Life
While tofu can last for weeks when properly stored, several factors affect its shelf life, including the packaging, storage temperature, and the date of manufacture.
Unopened tofu can last for two to three months in the fridge or freezer, depending on the packaging. If properly stored, an unopened pack of tofu can last up to six months in the freezer.
Here are some factors to consider when storing tofu:
Packaging: Airtight and vacuum-sealed packaging ensures that the tofu stays fresh for longer periods.
Storage Temperature: The optimal storage temperature for tofu is between 32-41°F. Therefore, any fluctuations in temperature could negatively affect its shelf life.
Date of Manufacture: Always check the date of manufacture before purchasing tofu. Purchasing fresh tofu and storing it at the right temperature will ensure optimal shelf life.
Pro tip: To extend the shelf life of tofu, consider blanching it before freezing or storing it in an airtight container with water.
Best-by, Use-by, and Sell-by Dates
Understanding the differences between best-by, use-by, and sell-by dates is crucial for making informed decisions about the freshness and safety of your food, including unopened tofu.
Best-by dates indicate when a product will retain its quality and flavor but may still be safe to consume after that date.
Use-by dates refer to when a product should be consumed for safety reasons. Consuming food after its use-by date can pose health risks.
Retailers use sell-by dates to indicate how long a product should remain on the shelves. However, consumers can still purchase and consume products after the sell-by date if stored and handled correctly.
Unopened tofu typically lasts about a week past its sell-by date if stored in the fridge at a constant temperature. However, it’s important to use your senses to determine if the tofu is still fresh and safe to eat, regardless of the date.
How to Store Unopened Tofu
Unopened tofu can last up to two months in the fridge; proper storage is essential to ensure freshness. Here are some tips for storing unopened tofu:
Check the “best by” or expiration date on the packaging before purchasing.
Store the tofu in its original package and ensure it is tightly sealed to prevent exposure to air and contaminants.
Keep the tofu in a consistent temperature environment, ideally between 36-40°F, to prevent bacterial growth.
Do not freeze unopened tofu, which can affect the texture and flavor.
When preparing to use the tofu, check for any signs of spoilage, such as a sour or musty odor, discoloration, or sliminess.
By following these simple steps, you can extend the lifespan of your unopened tofu and ensure that it is safe to eat.
Signs of Spoilage in Tofu
When storing unopened tofu, it is important to be aware of the signs of spoilage. While tofu that has gone bad can be a serious health hazard, it can also be relatively easy to identify. So before diving into how long unopened tofu can last in the fridge, let’s look at the signs of spoilage to be safe.
Mold Growth
Mold growth is a common sign of spoilage in tofu, and it is important to recognize the warning signs to prevent foodborne illness. Here is your ultimate guide to spotting signs of spoilage in tofu and storing it safely:
Signs of mold growth – Fuzzy, discolored appearance, a sour smell, and a slimy texture.
Storage – Store unopened tofu in the refrigerator and consume it before the expiration date.

Eating tofu within 3-5 days of opening is safe if stored correctly in the refrigerator. Always use your senses to check for any signs of mold or spoilage before consuming tofu. If it doesn’t smell or look right, discard it.
Remember, proper storage and correct consumption can prevent mold growth and prolong your tofu’s life. Pro-Tip: You can freeze tofu for up to 5 months to extend its shelf life.
Unpleasant Odor and Appearance
Tofu is a great protein alternative for many dishes, but it is susceptible to spoilage like any food. Here are some signs of spoilage to look out for:
Unpleasant odor – Fresh tofu should have a neutral scent. If you notice a sour or rancid smell, it indicates that it has gone bad.
Appearance – Fresh tofu should have a smooth and even texture, with no signs of discoloration or visible mold.
In addition to these visual and olfactory cues, always check your tofu’s expiration date and packaging.
Pro Tip: To prolong the life of your unopened tofu, store it in the refrigerator and check the use-by date. Once opened, transfer it to an airtight container filled with water and change it daily. Then, use it within 3-4 days for the best taste and quality.
Changes in Texture
Tofu is a versatile and healthy food used in various dishes. However, like all foods, tofu can spoil over time, so it’s important to know the signs of spoilage to ensure you’re consuming fresh and safe tofu.
Changes in texture are one of the primary signs of spoilage in tofu. Here’s what to look for:
Signs of Spoilage Description
Sliminess – If your tofu feels slimy or slippery, it is likely spoiled and should not be consumed.
Discoloration – It is likely spoiled if your tofu has changed color and appears yellow or brown instead of white.
Mushiness – If your tofu feels mushy or breaks apart easily, it is likely past its prime and should not be consumed.
Texture changes can be the first indicator of spoilage in tofu, but checking for any unusual odors or flavors before consuming is important. Proper storage can also help prolong the life of your tofu. Unopened tofu can last up to 5-7 days in the fridge, while opened tofu should be used within 3-4 days for best quality.
