Can fermented tofu with white mold still be eaten after being stored in the refrigerator?
Generally, tofu fermented with white mold that grows in the refrigerator is edible and usually does not cause harm to the human body.
The appearance of white mold on fermented tofu stored in the refrigerator is typically a normal phenomenon. Fermented tofu naturally develops a white surface mold during storage, which is a beneficial type of mold that generally does not affect its safety or usability and even provides certain nutritional benefits. During the fermentation process, fermented tofu produces abundant B vitamins, various minerals, and trace elements. It contains high levels of free fatty acids and amino acids, which can effectively inhibit angiotensin-converting enzyme after consumption and help regulate blood pressure. It also contains substantial amounts of unsaturated fatty acids that assist in lowering cholesterol levels in the body. However, individuals with cardiovascular or cerebrovascular diseases or gout should avoid consuming it, as fermented tofu is high in purines and may exacerbate their conditions.
If the mold on the surface of the fermented tofu appears grayish-green, it is usually toxic. Consuming such moldy tofu may lead to gastrointestinal discomfort symptoms such as diarrhea, abdominal pain, and loose stools. In severe cases, it could result in food poisoning or gastroenteritis.
