How to preserve fried peanuts for a long time and make them crispy

Deep fried peanuts can be stored in a sealed refrigerator or vacuum for long-lasting crispness. Fried peanuts are prone to moisture and softening, mainly due to factors such as storage containers, environmental humidity, temperature changes, oil oxidation, and storage time.

Frying peanuts in a well sealed glass jar or fresh-keeping box can effectively isolate air and moisture. A layer of oil absorbing paper can be placed inside the container to absorb excess oil and reduce oxidation reactions. Keep the storage environment dry and cool, and avoid direct sunlight that may cause oil to spoil. The temperature in the refrigeration room remains stable at around 4 ℃, which can slow down the moisture absorption rate of peanuts. However, it is important to note that they should be reheated before consumption to avoid affecting the taste.

Vacuum packaging can isolate oxygen to the greatest extent possible, and it is more effective when used in conjunction with food desiccants. Industrial packaging is often filled with nitrogen for preservation, and households can use vacuum machines for processing. Short term storage can be placed in a frozen layer, but the crispness will slightly decrease after thawing. Repeated thawing can cause water to condense, it is recommended to divide into small portions and freeze. Regardless of the method, it is recommended to consume it within a week to ensure the best taste.

During daily storage, be careful to avoid frequent opening and closing of containers, and seal them promptly after each use. Paired with silicone desiccant or food deoxidizer can extend the shelf life, but it is not advisable to directly contact peanuts. If you find that the oil flavor has turned sour or the taste is sticky, you should discard it immediately. Control the amount of frying in a single batch and make it fresher in batches. Before consumption, the oven can be reheated at 150 ℃ for 3 minutes to restore crispness, but deep frying should not be repeated. Choosing fresh peanut raw materials and thoroughly cooling them before storage can fundamentally improve the preservation effect.
