Mori-Nu Silken Tofu has a long shelf-life. The "best used by" date printed on the package represents one year to the day after it was made. That is, a tofu package marked best used by "DEC 31 21" was made on December 31, 2020. We guarantee at least a three (3) month shelf-life on all food products sold here in the online store. We do not recommend eating any Mori-Nu products after the "best used by" date. You do not need to refrigerate Mori-Nu Silken Tofu until the package is opened. For best results, store in a cool, dry place like your pantry or cupboard. We have many recipes that use Mori-Nu Silken Tofu straight from the box. Find them on the recipe page: https://morinaganutrition.com/pages/morinu-tofu-recipes. Refrigerate any unused portions promptly in an airtight container and use within 2-3 days maximum. You should not cover Mori-Nu Silken Tofu with water. As a source of protein, tofu is highly perishable once removed from the airtight package. To avoid foodborne illness, we do not recommend eating leftover tofu after 3 days. Tofu, like all moist protein, is considered to be "potentially hazardous" by the FDA unless it is packaged carefully and kept under refrigeration. In Japan, the tofu is thrown out if it becomes even two or three days old! That's because the Japanese are serious about fresh tofu and they know that spoiled tofu can ruin your whole day. Here in the United States, tofu is distributed sometimes thousands of miles from where it was made. Even tofu that has been pasteurized at the factory can go bad in transit or on the shelf. That's why Mori-Nu uses aseptic packaging. We know that this vital food is vulnerable to bacterial contamination and spoilage from contact with light or air. So, we use the very best in modern packaging and processing techniques. At our factory, we test every day to ensure each package of Mori-Nu Silken Tofu is 100% pure and free of bacteria and contaminants. Our long-time customers have learned to trust Morinaga, the Mori-Nu brand, and the tofu we make.

Thanks so much for your kind words! And thanks for being such a loyal fan!
