Therefore, you can purchase the age ahead of time, throw it into your home freezer, and thaw it out when you need to. Most packaged tofu is heat pasteurized, just like foods that are canned or fruits that are put up in jars for the summer. This ensures a longer shelf life, but it does destroy some of the delicate flavor of the tofu. It should be taken home and eaten the same day for the best flavor. You can keep it up to 4 days as long as you change the water every day and keep it refrigerated.

Both of these tofu have more flavor than you will find in other brands. Of course, the trade off is that they are much more perishable and should be consumed quickly. Once you open the tofu, taste it first to make sure it is not sour, especially if the date is close to expiration. You can keep it another 3 days or so, depending upon how fresh it was when you opened it. However, you should check your particular cook book or recipe to make sure they don't mean low sodium soy sauce.
