Generally, the normal shelf life of nuts is 240 days, but no matter how long it is kept, as long as it is spicy, it is definitely inedible. Because spicy nuts have been oxidized and rancid, long-term consumption will destroy some metabolic enzyme systems in the body, promote premature aging of the brain or dementia, and have adverse effects on the heart. If you want to preserve nuts for a long time, you should be very particular about the choice of containers. Nuts are recommended to be stored in sealed glass bottles or iron boxes, such as tea washing barrels and milk powder barrels. The temperature is lower than 15℃. If the indoor temperature is high, it can be sealed and put into the refrigerator for refrigeration. Minimize contact with air and moisture. Nuts are easily penetrated by odor, so they should be avoided to be stored with foods with pungent odor, such as onions, garlic, fragrant fruits, seafood, detergents, etc. Usually a small bag (5 5- 10/0g) of desiccant can store a can of 300g nuts. However, it should be noted that the bulk dried fruits purchased should be spread out and fully dried before they can be canned.
