Introduction
In general, whether fermented dough is still edible depends on its fermentation condition. It is normal for dough to ferment naturally after being kneaded. If the dough has no unusual odor, discoloration, or mold growth, it has not spoiled and is safe to consume. However, if the dough turns yellow, develops a sour or foul smell, or shows visible mold spots on the surface, it has spoiled and should not be eaten.

Natural fermentation of kneaded dough is a normal process. If the dough shows no signs of off-odor, discoloration, or mold, it has not spoiled and can be safely eaten after being thoroughly cooked, with little to no adverse effects on health.
When dough undergoes natural fermentation in a warm environment for an extended period, excessive microorganisms and bacteria may develop, which are harmful to human health. The dough may turn yellow, emit a sour or unpleasant odor, or even show visible mold spots—indicating spoilage and making it unsafe for consumption. Accidental ingestion may lead to gastrointestinal discomfort such as nausea, vomiting, abdominal pain, and diarrhea. In severe cases, it could result in food poisoning.
It is recommended that leftover dough be stored in a refrigerator or a cool, well-ventilated place to prevent spoilage. In daily life, it's best to consume fresh food whenever possible.
