How does peanuts become brittle when they regain moisture

After the peanuts regain moisture, they can be restored to their crispness by heating, baking, or microwave treatment. The rehydration of peanuts is mainly caused by moisture, leading to an increase in moisture content. Removing moisture can improve the taste.

Spread the rehydrated peanuts flat on a baking tray and place them in a preheated oven to bake at low temperature. The temperature is controlled at around 100 degrees Celsius for about 10 minutes. During this period, it is necessary to flip it several times to ensure even heating. This method can effectively evaporate excess water while avoiding burning caused by high temperatures. The roasted peanuts will regain their crispy texture after cooling, but it is important to seal and store them to prevent them from getting damp again. Using a microwave oven for processing is also a fast and effective method. Spread the peanuts flat in a microwave specific container, heat on medium high heat for 30 seconds, then remove and flip, repeat until the crispness is restored. The evaporation rate of water is fast during microwave heating, but the time should be strictly controlled to prevent overheating. This method is suitable for rapid processing of small amounts of peanuts, and it is recommended to heat them in batches for a short period of time and observe the changes in state during operation.

When processing rehydrated peanuts, it is important to avoid using excessively high temperatures, as high temperatures may lead to oil oxidation and nutrient loss. Peanuts that have regained their crispness should be consumed as soon as possible or stored in a sealed container. Food desiccants can be added to extend the storage time. It is recommended to choose a cool and dry environment for daily storage of peanuts. After opening, seal it in a timely manner to reduce contact with air and effectively prevent moisture regain.
