Shell to Meat Formula

Here are some easy formulas to convert in-shell pecans to nutmeat:
(all conversions are approximate)
One pound of in-shell pecans will yield 2¼ cups of nutmeat.
Twelve pecan halves will yield 3 tablespoons of chopped nutmeat.
For a pound of nutmeat, you will need 2½ pounds of in-shell pecans.

Handling and Storage of Pecans

In order to help you maintain the highest quality pecan meats, we have developed the following guide to help you understand the best way to handle and store your pecans. 

 General Information

  • Pecans contain a high oil content, and thus are prone to spoilage, or rancidity over time if not stored properly.
  • Roasted and candied pecans are even more prone to rancidity as they have been subjected to very high temperatures in the process.
  • Pecans should be protected from moisture, light, heat, and oxygen to preserve freshness.
  • Pecans can be thawed and refrozen repeatedly without loss of flavor or texture.
  • Pecans should not be stored with odorous products such as apples, onions, spices, etc., and should not be stored in facilities cooled by ammonia.
  • For best retention of flavor, pecans should be stored under refrigeration. Storage life of the nut is extended by lowering the temperature.  The average shelf life for shelled pecans at several storage temperatures is shown below.


Storage Temperature              Average Shelf Life

            65-70°F                                    45 days

            45°F                                         6 months

            32°F                                         12 months

            20°F                                         18 months

            0°F                                           2-3 years



Proper tempering of frozen pecans is vital to retaining maximum quality of the nut.  Frozen pecans should be tempered in a cooler room with temperatures of 36°F - 47°F with relative humidity of 65% - 75% for a period of 72 hours before moving them into room temperature.  This will allow any condensation that may form on the pecans to dissipate.  If pecans are not tempered properly, the condensation that may form on the pecans will create conditions where mold is likely to develop.  Therefore a series of gradually increasing temperatures is desirable.
