How long can melon seeds and peanuts be stored

Melon seeds and peanuts can usually be stored for 6-12 months when unopened and properly stored. It is recommended to consume them within 1-3 months after opening. The storage time is affected by factors such as storage environment, packaging method, and initial state of the product.

Melon seeds and peanuts contain high levels of oil and fat, and are prone to oxidation and deterioration when exposed to air for a long time, resulting in a spicy taste. Unopened vacuum packaging can effectively isolate oxygen and moisture, extending the shelf life to about 12 months. When storing, it should be placed in a cool and dry place, avoiding direct sunlight and high temperature environment. It is ideal to control the temperature below 20 degrees Celsius. A humid environment can cause nuts to become damp and moldy, leading to the growth of harmful substances such as aspergillus flavus. Therefore, the humidity should be kept below 60%.

After opening, melon seeds and peanuts oxidize faster due to exposure to air and moisture. It is recommended to store them in sealed cans or food grade sealed bags. If the taste becomes soft, the color darkens, or there is an odor, it indicates that it has deteriorated and is not suitable for consumption. During the hot and humid summer season, the storage time may be shortened to about one month. Freezing storage can be extended for more than 6 months, but the taste may slightly change after thawing, making it suitable for cooking rather than direct consumption.

When storing melon seeds and peanuts in daily life, it is recommended to divide them into small portions for use to reduce the number of times they are opened. Can be paired with desiccants or food deoxidizers to enhance moisture resistance. Choosing original flavor products is more durable for storage than seasoned ones, as spices and salt may accelerate oil oxidation. If long-term storage is required, it is recommended to choose nuts with shells as the outer shell can provide an additional protective layer. Regularly check the status of inventory food to avoid consuming spoiled nuts that may affect health.
