Can you still eat qingtuan if it has become hard?

It is not recommended to consume green rice balls (qingtuan) once they have hardened. Hardened qingtuan may undergo changes in composition due to moisture loss and starch retrogradation, which can easily cause gastrointestinal discomfort such as bloating, abdominal pain, and diarrhea after consumption. If persistent vomiting, severe abdominal pain, or fever occurs after eating, seek medical attention promptly.

Green rice balls are primarily made from glutinous rice flour. Once hardened, the starch structure changes and becomes difficult for digestive enzymes to break down, increasing the digestive burden on the gastrointestinal tract. This may lead to more pronounced discomfort, especially among individuals with weak digestive systems. Additionally, improper storage during the hardening process may promote bacterial growth and other harmful substances, posing a risk of acute gastroenteritis if consumed.

Always check the condition of green rice balls before consumption; if they have already hardened, avoid eating them. For daily storage, keep qingtuan sealed in a cool, dry place or refrigerated to prevent moisture loss and bacterial growth. Before eating, soften them by steaming or boiling to ensure food safety and smooth digestion.
