Tofu is made from soybeans, which are first soaked in water and then ground into a paste. The soybean paste is then mixed with water and heated until it boils. A coagulating agent, such as calcium sulfate or magnesium chloride, is then added to the mixture to cause the soy milk to curdle and form solid curds. The curds are then pressed together to form blocks of tofu. 

Depending on the desired texture, the tofu may be pressed lightly to create softer tofu or more firmly to make firmer tofu. Some tofu may also contain additional ingredients such as herbs, spices, or vegetables to add flavor and variety. Overall, tofu is a nutritious and versatile food that is enjoyed by many people around the world.

5. Is tofu good for you? Is tofu healthy?

Yes, tofu is generally considered to be a healthy food. It is a good source of protein and contains all nine essential amino acids that our body needs to function properly. 

Tofu is also low in saturated fat and cholesterol-free, making it a heart-healthy option. Additionally, tofu is a good source of calcium, iron, other minerals, and vitamins like B12 and D, commonly found in animal products. 

Eating tofu and other soy products has been linked to various health benefits, including a lower risk of heart disease, certain cancers, and osteoporosis. However, as with any food, it’s important to eat tofu in moderation and as part of a balanced diet.


6. How long does tofu last?

The shelf life of tofu depends on the type of tofu and how it is stored. In general, unopened tofu can last for several weeks in the refrigerator, while opened tofu should be consumed within a few days.

For soft tofu, it is recommended to consume it within 3-5 days of opening. For firm or extra-firm tofu, it can last up to a week in the refrigerator after opening.

If you want to extend the shelf life of tofu, you can freeze it. Frozen tofu can last for several months in the freezer, but the texture may change when it is thawed. For example, thawed tofu may become more crumbly and have a different texture than fresh tofu.

To ensure the longest shelf life for tofu, store it in a sealed container with water in the refrigerator. Change the water daily to keep the tofu fresh. It should be discarded if the tofu smells, looks off, or has a slimy or moldy texture.

7. How to store tofu?

  1. Keep tofu refrigerated: Tofu should always be stored in the refrigerator to keep it fresh. After purchasing tofu, make sure to place it in the fridge as soon as possible.
  2. Store tofu in water: Tofu should be stored in water to prevent it from drying out. Place the tofu in a container and cover it with water. Change the water every day to keep the tofu fresh.
  3. Keep tofu in its original packaging: If the tofu is unopened, it can be stored in its original packaging. Once the packaging is opened, transfer the tofu to a container of water and store it in the refrigerator.
  4. Use or freeze tofu within a reasonable time: Tofu is best consumed within a few days of opening. If you don’t plan on using it immediately, consider freezing it.
  5. Freeze tofu: To freeze tofu, drain off the water and wrap the tofu tightly in plastic wrap or place it in a freezer-safe container. Freeze for up to 3 months. Thaw tofu in the refrigerator before using it.
