Can 2-year dried peanuts with shells still be eaten

Dried peanuts with shells for 2 years, if stored properly and without any abnormal conditions such as mold or odor, can generally be consumed. If there are signs of moisture, insect infestation, or spoilage, it is not recommended to continue consuming. Dried peanuts with shells stored in a dry and cool environment, with intact and undamaged shells, can usually maintain their quality for a longer period of time. Peanuts have a high internal oil content, but the outer shell can effectively isolate air and moisture, delaying oxidation and deterioration. Before consumption, it is necessary to carefully check whether the outer shell is moldy or discolored. After peeling off, observe whether the nuts remain a normal light yellow color and whether there is a crackling or other unpleasant odor when smelled. Peanuts that have been slightly damp can be dried by air drying or low-temperature baking, but moldy peanuts that have produced aflatoxin must be discarded.

High temperature and high humidity environments can cause peanut shells to adsorb moisture, accelerate mold growth, and cause oil spoilage. If exposed to pests or rodents during storage, it may carry pathogenic bacteria. Even if peanuts are stored for a long time and have a normal appearance, their nutritional value will gradually decrease, and protein and fat may undergo denaturation. Some people are sensitive to the oxidation products in old peanuts and may experience gastrointestinal discomfort after consumption.

It is recommended to store peanuts with shells in a sealed container, in a well ventilated and dry place, and avoid direct sunlight. Buying in small quantities and consuming as soon as possible is the best way to ensure flavor and nutrition. People with special physical conditions and infants should choose fresh peanuts. If they experience discomfort symptoms such as abdominal pain and diarrhea, they should immediately stop eating and seek medical attention. Low temperature refrigeration can be used to extend the shelf life in daily life, but it is important to seal and prevent moisture.
