Can I still eat purple sweet potatoes after they have sprouted?

Generally speaking, whether sprouted purple sweet potatoes can be eaten depends on the specific condition of the potato and requires analysis and judgment accordingly. The detailed analysis is as follows:

If the purple sweet potato has only sprouted slightly, with no mold, black spots, or damage on the skin, and the inside remains firm, without rotting or odor after cutting open, it can usually be eaten after removing the sprouted portion and a small amount of surrounding flesh. Although some nutrients may have transferred to the sprouts and the texture may be slightly compromised, no harmful substances are produced. After thorough washing and adequate heating, these potatoes can be safely steamed, boiled, or used to prepare complementary foods.

If the purple sweet potato has sprouted severely, with long sprouts, mold spots or black patches on the skin, or if the inside appears brown, soft, rotten, or has an odor after cutting open, it should not be consumed. During severe sprouting, purple sweet potatoes may easily develop mold and potentially produce toxins. Even after removing the sprouted and moldy parts, toxins may have spread to the remaining flesh. Consumption may cause nausea, abdominal pain, diarrhea, or other gastrointestinal discomforts, which may affect health.

When storing purple sweet potatoes, they should be kept in a cool, dry, and well-ventilated place, avoiding direct sunlight and humid environments to reduce the likelihood of sprouting and mold growth. Carefully inspect both the exterior and interior condition of the potato before consumption, and do not eat it if safety cannot be confirmed. Ensure the purple sweet potato is fully cooked before eating, and avoid consuming it raw. If discomfort occurs after consumption, stop eating immediately and monitor symptoms.
