How to make shelled peanuts brittle when they become damp

Shelled peanuts can be restored to their crispness by low-temperature baking, microwave heating, sun drying, freeze-drying, or co storage with desiccants after being damp. Attention should be paid to temperature control and mold prevention during processing, and moldy peanuts must be discarded.

1. Low temperature baking

Spread damp peanuts flat on a baking tray and bake them in a preheated oven at 100 degrees Celsius for 15 minutes. Low temperature slow dehydration can prevent the shell from burning and preserve the oil aroma of peanut kernels. This method is suitable for batch processing, and after baking, it needs to be thoroughly cooled and sealed for storage.

2. Microwave Heating

Take an appropriate amount of peanuts and place them in the microwave. Heat on medium heat for 30 seconds, then flip and repeat 2-3 times. Microwaves can quickly evaporate water, but close observation is necessary to prevent local overheating. After processing, peanut shells will become hard and brittle again, suitable for emergency handling in small quantities.

3. Sun drying and dehydration

On sunny days, spread the peanuts on a bamboo sieve and let them air dry in a well ventilated area for 6-8 hours. The ultraviolet rays in sunlight can also inhibit the growth of mold, making it suitable for use in areas with low humidity. Be careful not to expose to direct sunlight, which may cause oil to spoil, and store it promptly after exposure to sunlight.

4. Freeze drying

Put peanuts into sealed bags and place them in the freezer for 24 hours. After the moisture condenses at low temperature, take them out and let them stand at room temperature. The freezing process can maintain the original flavor of peanuts, but it is necessary to ensure that the packaging is completely sealed to avoid secondary moisture caused by condensed water.

5. Storage of desiccants

Put peanuts and food grade desiccants together in a sealed container and let it stand for 48 hours. Desiccant can slowly absorb moisture from peanut shells and is suitable for mild moisture conditions. After use, it is necessary to replace the desiccant in a timely manner to prevent reverse moisture absorption.

It is recommended to use double-layer sealed cans for daily storage of peanuts with shells, with food desiccants placed on the inner layer, and stored in a cool and ventilated place. Avoid using plastic bags for long-term storage and regularly check for signs of mold. If mold or crackling odor is found, it should be discarded immediately. Aflatoxin is heat-resistant and harmful to health. Peanuts that have regained their crispy texture should be consumed as soon as possible, as their taste will significantly decrease after being dampened again. When making nutritious snacks with ingredients such as red dates and oats, fresh roasted peanuts are preferred to ensure flavor.
