Expiration & Storage Tips
When does firm tofu expire?
Unopened and refrigerated firm tofu can last up to a week past its best-before date. Compare this to your tofu's printed expiration date to keep track. Once you've opened the tofu, try to use it within three to five days. If you decide to freeze the tofu, believe it or not, it can dramatically extend its life for up to 5 months. Giving it a new, chewier texture, frozen tofu can be a pleasant surprise.
How do you tell if firm tofu is bad?
If your tofu has gone bad, you'll notice a few key signs. The original white color will have deepened to a yellow, tan, or even green. The texture could resemble that of blue cheese, growing increasingly slime-like. In terms of smell, fresh tofu should not have a strong odor. If it smells sour, rancid, or extremely off-putting, it's time to toss it.
Tips for storing firm tofu to extend shelf life
• Store the tofu in an airtight container filled with water, in the refrigerator.
• Change the water daily to keep the tofu fresh.
• Freeze your tofu in blocks. This changes its texture, making it more meat-like. To defrost, just leave it in the fridge for a couple of days or speed up the process by microwaving it for several minutes on the defrost setting.
• Seal leftovers properly before refrigerating to prevent them from absorbing other food odors.
• If your tofu comes with a protection seal, only remove it when you’re ready to use the tofu.
