Introduction
If the potatoes are immediately soaked in clean water after cutting and stored in the refrigerator's cold compartment at a temperature maintained around 4°C, this low-temperature environment can effectively inhibit bacterial growth and delay the spoilage of the potatoes. Under these conditions, after storing the potatoes overnight (not exceeding 24 hours), if there is no mold growth, discoloration, or development of an unusual odor,
Soaked potatoes can generally be eaten the next day if properly stored and show no signs of spoilage or odor. However, if stored improperly and signs of spoilage occur, they usually shouldn't be consumed the next day.
If the potatoes are immediately placed in clean water for soaking after being cut and stored in the refrigerator's chilling compartment at a temperature around 4°C, this low-temperature environment can effectively inhibit bacterial growth and delay spoilage. Under these conditions, potatoes soaked overnight are generally safe to cook and eat if there are no signs of mold, discoloration, or unpleasant odors.
If the soaked potatoes show signs of spoilage, such as an unpleasant odor, mold growth, or darkened color, or if contaminated water was used, they shouldn't be eaten. Spoiled potatoes may contain harmful bacteria or toxins that could negatively affect human health. Additionally, soaking potatoes in a high-temperature environment can accelerate spoilage and increase the risk of consumption. Even if the potatoes haven't spoiled, soaking them for too long may lead to nutrient loss and a decline in texture, so consumption is not recommended.
Avoid leaving cut potatoes for extended periods, especially at room temperature. When cooking, ensure the potatoes are thoroughly cooked to guarantee food safety.
