Can raw peanuts be put in the refrigerator?

A lot of food will spoil if we don't eat it in time. Therefore, many people store food through the freezing function of the refrigerator. Although this is also an effective method of food preservation, it will greatly affect the taste and nutrition of the food. For peanuts, many people will freeze them. So, can raw peanuts be kept in the refrigerator?

Can fresh peanuts be refrigerated?

Fresh peanuts can be stored in the refrigerator. As one of the traditional foods loved by the people, peanuts have been known as the "longevity fruit" since ancient times. A folk proverb says: "Eating peanuts regularly can keep you healthy." Studies have found that peanuts have certain medicinal value and health-care functions.

Storage methods of fresh peanuts:

The main deterioration phenomena of peanuts during storage are mold, discoloration, loss of oil and hardness. The moisture content of peanuts exceeds 10%, and the moisture content of peanut kernels exceeds 8%, so they are prone to mold when the high temperature season comes. Therefore, during storage, it is necessary to properly control the three aspects of dryness, low temperature and airtightness.

Put one or two cigarettes in the container or plastic bag containing peanuts and seal the opening tightly to prevent air leakage. In this way, the peanuts will not be eaten by insects within three years. After taking out the peanuts, continue storing them using this method.

Wash the peanuts with clean water, drain and fry them, mix them evenly with fine salt and five-spice powder, then spread them out to dry, and put them into plastic bags or other sealed containers after they are dry. Treating the peanuts in this way will make them lose their ability to germinate and they will not deteriorate even after the summer.

The seed coat of peanuts (called red coat in the grain) is easily discolored due to the influence of light, oxygen, high temperature, etc. If the color changes from the original fresh light red to dark red or even dark purple, it means that the quality is beginning to deteriorate and measures should be taken immediately to improve storage conditions.

Storage conditions of fresh peanuts

1. Peanut storage: Peanuts can be stored loosely in warehouses or in the open air. The moisture content must be controlled within 10% and the stacking height should not exceed 2 meters. After ventilation and cooling in winter, it is better to store it in a sealed container while it is still cold.

2. Storage of peanut kernels: When storing peanut kernels, the moisture content must be controlled within 8%, and the maximum pile temperature should not exceed 20°C. It should be sealed in time to prevent pest infection and the influence of external temperature and humidity, and the pile should be kept dry, low in temperature and low in humidity. Only in this way can the quality of peanut kernels be better maintained. Peanut kernels can also be stored in a controlled atmosphere. For example, if the vacuum degree is 400 mm Hg and an appropriate amount of nitrogen is added, the respiration intensity of the peanuts and insect and mildew erosion can be inhibited.
