Always keep your pecans in clean and dry containers to protect them from insects and odors.  Their high oil content absorbs foreign flavors readily.

Pecans should be kept under refrigeration to best preserve their fresh color, aroma, and flavor.  The lower the temperature, the longer the nuts will keep.

Pecans stored at room temperature will remain fresh for only about 2 months; in the refrigerator they may be kept for about 9 months; and in the freezer, they will remain in good condition for 2 years.
