Recommendations vary, but most sources say walnuts will last up to 3 months in the pantry, 1 year in the refrigerator, and 3 years in the freezer. However, shelf life varies depending on temperature, type of nut, and whether it is peeled, roasted, or whole pieces. The length of time you can store food is important, from a safety and taste standpoint. The storage period can be extended by vacuum sealing.
This process involves storing food in specially designed vacuum containers. The vacuum packaging process removes air from the package and creates an airtight seal. Vacuum packed nuts vary in whether they are normally packed or vacuum sealed. There are certain actions you can take to optimize the usefulness of the vacuum packaging process and ensure that you achieve maximum storage times.
Using vacuum bags helps you extend this storage time by keeping food in good condition for longer periods of time. It's worth investing a little time and effort, as using these tips helps maximize the time that vacuum-packed foods stay fresh. For items stored in the freezer, vacuum packaging can also prevent the freezer from burning, providing greater protection for your food. However, in the event that you open the seal every other day, you would have to vacuum seal the bag every time you open it.
Another option is to vacuum seal the nuts and then store them in the refrigerator instead of in the freezer.
