Here are some useful tips I’ve learned about nut storage:
- Nuts need to be stored carefully because of their high oil/fat content. They will go rancid if not stored properly.
- The definition of rancid is “having a rank smell or taste usually due to a chemical change or decomposition.” A rancid nut can upset your stomach. They are yucky.
- Nuts store longest in the freezer (about 8 months to a year), but they can be stored in the refrigerator for about 4 months.
- Store nuts in an airtight, moisture proof container in a dark, cold (less then 70 degrees), dry, safe-from-rodent place. Glass jars or Ziploc bags with the air removed work well. If you have a Foodsaver with a Mason jar attachment, you can remove the air. (I want one of these!)
- Unsalted nuts stay fresher longer than salted nuts.
- Whole nuts last longer than chopped nuts.
- Nuts in the shell store longer than nuts out of the shell. However, if you are limited on freezer space, replenish shelled nuts often.
- Mark the container with the date you purchased the nuts.
- Nuts are high in fiber, fat (primarily unsaturated fat) and protein.
- Smell, then taste a nut before using.
Here is an interesting 5 minute video on how pistachios are harvested and processed.
