What method can be used to make peanuts crispy when they are no longer crispy

Peanuts that are no longer crispy can be restored to their crispness through methods such as re roasting, microwave heating, deep frying, freezing, or placing them together with desiccants. The softening of peanut rice due to moisture is mainly related to high humidity or inadequate sealing in the storage environment, and appropriate methods should be selected according to the actual situation for treatment.

1. Re bake

Spread the damp peanuts flat on a baking tray and bake in a preheated oven at 150 degrees Celsius for 5-8 minutes. High temperature can evaporate excess water, making peanuts crispy again. During the baking process, it is necessary to flip it 1-2 times to ensure even heating, and pay attention to observing the color to avoid burning. This method is suitable for peanuts with low quantity and high taste requirements.

2. Microwave Heating

Spread the peanuts flat in a microwave oven container, heat on medium high heat for 30 seconds, then remove and flip them, repeat 2-3 times until the crispness is restored. Microwaves can rapidly vibrate and heat water molecules, effectively removing moisture in a short period of time. It is recommended to heat it in batches for a short period of time during operation to avoid local overheating and bitterness. This method is suitable for quickly processing small amounts of peanuts.

3. Fry

Put peanuts in cold oil and fry slowly over low heat until small bubbles appear on the oil surface. Remove and drain the oil. Oil thermal conductivity can deeply remove moisture and impart a richer aroma. Control the oil temperature to avoid burning, and sprinkle a small amount of salt after removing to enhance the flavor. This method is suitable for large-scale processing that requires fragrance enhancement, but it will increase the intake of extra oil.

4. Freezing treatment

Seal the peanuts and place them in the freezer for 2 hours. Low temperature can cause residual moisture to freeze and sublime. After removal, let it stand at room temperature for 10 minutes. The evaporation of ice crystals can partially restore the brittleness of peanuts. This method is effective for mild moisture and can preserve the original nutrients to the greatest extent possible, but the degree of taste recovery is limited.

5. Place desiccants together.

Seal and store damp peanuts and food grade silicone desiccants together for 12 hours. Desiccants can actively adsorb water vapor in the environment, making them suitable for handling situations where they have not completely softened. Before use, ensure that the desiccant has not expired and avoid direct contact with peanuts. This method is easy to operate but has a slow effect, making it suitable for situations where it is not urgently needed for consumption.

It is recommended to use sealed cans or vacuum bags for daily storage of peanuts, and store them in a cool and dry place to avoid moisture. If the peanuts have developed a rancid or moldy taste, they are not edible. The aflatoxin produced by mold is heat-resistant and highly carcinogenic. Peanuts that have regained their crispness should be consumed as soon as possible, as repeated exposure to moisture can accelerate fat oxidation. Eating vegetables rich in dietary fiber such as celery and carrots can help balance oil intake. Special populations such as gallbladder disease patients need to control their consumption of fried peanuts.
