It is generally not recommended to consume peanuts that have been burnt. Boiled peanuts may produce harmful substances, and their taste and nutritional value will significantly decrease. Long term heating of peanuts at high temperatures can cause carbonization, resulting in a burnt and bitter taste. In this state, protein and fat structures are disrupted, and a large amount of nutrients such as vitamins are lost. The burnt portion may contain carcinogens such as benzo [a] pyrene, and long-term intake can increase health risks. After removing the black part of slightly burnt peanuts, the remaining non spoiled part can be consumed in small amounts, but attention should be paid to whether there is mold or odor. If peanuts show large areas of burnt black or obvious bitterness, they should be discarded directly. Burnt food may irritate the gastrointestinal mucosa, causing discomfort symptoms such as nausea and abdominal pain. Improper storage of peanuts can easily breed aspergillus flavus, and high temperatures cannot completely destroy their toxicity, making them even more harmful when combined with burnt rice. Special populations such as children, pregnant women, or patients with digestive system diseases should avoid consumption.

It is recommended to control the heat when cooking peanuts in daily life, and use low heat to cook slowly or steam them. Choose fresh and mold free peanuts, and soak them thoroughly before cooking to shorten the heating time. If occasionally consuming slightly burnt peanuts, it is recommended to pair them with vegetables and fruits rich in vitamin C to help reduce the absorption of potential harmful substances. The storage of cooked peanuts should be sealed and moisture-proof to avoid repeated heating that may cause quality deterioration.
