How do peanuts become brittle when they become soft

Peanuts can be restored to their crispness by baking or frying after becoming soft. The moisture content of peanuts softened by moisture increases, and high-temperature dehydration is needed to re stimulate the oil aroma and brittleness.

Spread the softened peanuts flat on a baking tray and bake at 150 degrees Celsius for 10 minutes, flipping halfway to ensure even heating. Low temperature slow baking can evaporate internal moisture without easily burning, suitable for people who pursue health and low oil consumption. If using an air fryer, heat it at 180 degrees for 5 minutes, and high-temperature hot air circulation can quickly remove moisture. After baking, peanuts should be thoroughly cooled and sealed for storage to avoid residual heat returning to moisture.

Put peanuts in a cold oil pan, fry slowly over low heat until the color turns slightly yellow, then remove and control the oil. Frying uses oil to conduct heat, which can more thoroughly remove moisture and form a crispy texture, but the high calorie content requires controlling the amount consumed. During the frying process, it is necessary to continuously flip to prevent local coking. After removing, sprinkle a small amount of salt to enhance the flavor. This method is suitable for scenarios that require rapid crisping or making seasoned peanuts.

It is recommended to consume the crispy peanuts within 24 hours and store them in a moisture-proof jar or vacuum sealed bag. Avoid storing peanuts in damp environments such as refrigerators, and place food desiccants to absorb excess moisture. Peanuts are rich in unsaturated fatty acids and protein. Moderate consumption is beneficial for cardiovascular health, but it is recommended to limit the daily intake to less than 30 grams. Moldy peanuts can produce aflatoxin, and if any odor or mold spots are found, they should be discarded immediately.
