Pine nuts can go bad. These costly nuts come with a sell-by date and should be used up within a couple of weeks. If they are left past their expiration date, their quality will degrade and be unusable. When storing pine nuts, it is best to keep them in the fridge or freezer to prolong their expiration date.
Read on to determine how to store pine nuts and how you can identify if they have gone bad and are on the verge of being bad.
Do Pine Nuts Go Bad? How Long Do Pine Nuts Last?
Compared to other nuts, pine nuts have a relatively short shelf life. Due to their high oil content, they go bad quite quickly, depending on when and how you store them.
How Long Do Pine Nuts Last Outside?
Pine nuts should only be stored in the pantry if they are unopen. Unopened packaging will eliminate the oxidization process and keep the nuts going rancid for up to two months past the sell-by date.
An opened container of pine nuts should not be stored at room temperature. The oxidization and the oil will cause the nuts to spoil in a much quicker period.
It is important to note that unshelled pine nuts will help protect the oil and keep the nuts from spoiling. Unshelled nuts are more susceptible to ruin due to lack of protective coating and should be stored cold instead of cool.
How Long Do Pine Nuts Last in the Fridge?
Pine nuts, when unshelled, should be stored in the fridge. The cold will help keep the oil from spoiling and keep them useable for a couple of months.
An unopened pine nuts package can be stored in the fridge due to the cold oxidation process and will help extend its shelf life. The pine nuts should only be kept in their packaging until they are opened due to the higher possibility of oxidation and bacteria getting to them.
An opened package should be poured into an airtight container or bag when stored in the fridge to keep them from spoiling. When stored correctly, all pine nuts can be kept for one month past their expiration date.
How Long Do Pine Nuts Last in the Freezer?
To prolong the lifespan of pine nuts, you can place them in the freezer. The freezer will keep the nuts cold enough and the oil from spoiling by freezing them.
The shelf life of pine nuts in the freezer is brought up to three months past their expiration date. It is best to keep them in a resealable freezer bag to keep moisture from contaminating your nuts.
Shelled and unshelled pine nuts can be frozen, but it is important to thaw them before using them due to their ability to become completely frozen and unusable.
The best place to store pine nuts is in a cold fridge or freezer. This will keep the oil from degrading and ensure that the pine nuts have an as long shelf life as possible.
