Can you Freeze Tofu? Refrigerated Vs. Shelf-Stable

Can you Freeze Tofu Refrigerated Vs. Shelf-Stable

Tofu freezes quickly and lasts for three to six months when stored in a freezer. Tofu can even last up to a year when properly stored in the freezer, and there is no harm in consuming the frozen tofu within one year. However, the texture and taste may degrade over time.

If you want to preserve your tofu for up to 365 days, you need to freeze it, and there are certain things you need to keep in mind before freezing it.

  • Divide the package of tofu into small portions as it helps you to thaw only the required portion and not the entire tofu. Re-freezing is not a good option for tofu.
  • Remove excess water from the container before freezing it, and squeeze the tofu to drain it before chopping.
  • Wrap the small pieces into a small freezer bag and zip-lock the package before storing it in a freezer.
  • You must refrigerate the tofu overnight before thawing. Never leave it on your kitchen top after taking it out from the freezer.

Refrigerated

Tofu needs continuous refrigeration to keep its quality longer. You have to refrigerate unopened and leftover tofu in a fridge, regardless of the variety.

Only the shelf-stable variety can last outside a refrigerator at room temperature. So, you have to check the label to confirm the variety you have purchased and store it accordingly.

However, the shelf-stable variety of tofu only lasts at room temperature until it is sealed and unopened. Once it is opened, you need to refrigerate it like other varieties of tofu.

If you are unsure which variety you have bought from the store, place it inside your fridge as it works fine for all the varieties.

 

Shelf-Stable

Tofu is not shelf-stable food, and hence it needs refrigeration right from the time you buy it from a store. However, shelf-stable variety keeps its quality and taste even when stored at room temperature. But, it will only last at room temperature until unopened, as after opening, you need to refrigerate it like other varieties.

Raw Tofu can sit outside a fridge for only two hours once it is cooked. Keeping it outside for more than two hours can increase the chance of bacterial growth as it is a perishable food.

So, apart from unopened shelf-stable variety, all varieties of tofu need refrigeration as they are not shelf-stable food.
