We are very familiar with tofu. The meat of tofu is delicious and the taste is very good. Its main component is protein. So can overnight tofu be eaten? It depends on the specific situation, because tofu contains The rich protein itself can easily cause the growth of filamentous bacteria. If it is hot summer, overnight tofu may deteriorate and become inedible, so overnight tofu should be stored in a cool environment.

If you will not eat the purchased raw tofu that day, it should be sealed in a crisper and placed in the refrigerator to reduce the growth of bacteria. It can be stored for 2 to 4 days. If there is no refrigerator at home, you can put the crisper in water with a lower temperature. It is best to eat it the next day.

Fresh tofu can be stored at room temperature for up to six or seven hours, but if it is not consumed on the same day, it should be stored in the refrigerator immediately and is best eaten the next day. If you want to preserve it longer, you can blanch it in boiling salt water and put it in the refrigerator. It can be stored for about two days. Blanching in salt water can not only reduce the growth of microorganisms, prevent tofu from becoming sticky, and extend the storage time, but can also remove the bitter taste of brine tofu, thereby making the aroma of tofu more prominent. However, when cooking tofu blanched in salt water, you should add less salt, otherwise it will easily lead to excessive salt intake.

Tofu, like meat, is rich in protein, so bacteria can easily breed in poor ventilation and high temperatures, making tofu sticky. If the strain is pure, there is no need to worry about its safety. For example, the strains used in fermented bean curd processing plants will hydrolyze protein and precipitate amino acids under certain conditions to obtain nutrients that are more conducive to human body absorption, such as calcium, essential amino acids, etc., and at the same time enhance the umami flavor of tofu. These ingredients are Harmless to human body. However, there are many bacteria in the home environment, and harmful bacteria will be mixed with them. Some of them will produce toxins. Even washing with hot water cannot guarantee that they will be completely washed away. Therefore, it is not recommended to eat sticky tofu.
