Can tofu still be eaten after being stored for ten days

Tofu that has been stored for ten days is usually not recommended for consumption. Tofu is a high protein perishable food, and it is generally stored in cold storage for no more than 3-5 days. Storing it at room temperature is more likely to breed bacteria. If it becomes sticky, sour, or moldy, it is absolutely not edible. Fresh tofu has a high water content and is rich in plant protein, allowing for rapid microbial growth at suitable temperatures. Even in a refrigerated environment, the deterioration process can only be delayed, and a storage time of ten days far exceeds the safe limit. At this point, tofu may have developed pathogenic bacteria such as Clostridium botulinum, which cannot be identified by the naked eye, but consuming it may cause abdominal pain, diarrhea, and even food poisoning. Especially in high temperature environments or packaging damage during summer, the risk of tofu spoilage is higher.

Partially vacuum packaged sterilized tofu can theoretically have a shelf life of up to two weeks under unopened and fully refrigerated conditions. However, it is difficult to ensure constant temperature conditions for home storage, and exposure to air after opening will accelerate deterioration. If the surface of tofu is only slightly dry without any odor, it can be consumed with caution after boiling at high temperature for ten minutes, but its nutritional value and taste have significantly decreased.

It is recommended to purchase fresh tofu as needed for daily use. When storing it in refrigeration, soak it in cold water and change the water daily. If the texture of tofu becomes sticky, its color turns red, or it emits a strange odor, it should be discarded immediately. Special populations such as pregnant women, children, or those with low immunity need to pay close attention to food safety and avoid consuming soy products that have been stored for too long. If symptoms such as vomiting and fever occur after ingesting spoiled tofu, seek medical attention promptly.
