How many walnut kernels can be peeled from 1 pound of dried walnuts

1 pound of dried walnuts can usually peel about 300 to 350 grams of walnut kernels, and the specific kernel yield depends on factors such as walnut variety, dryness level, and shell thickness.

There are significant differences in the hardness of walnut shells and the plumpness of kernels among different varieties. Paper skinned walnuts have a thin and brittle shell that is easy to peel, with a kernel extraction rate of about 70%, while thick shelled walnuts may require specialized tools to break the shell, resulting in lower kernel integrity. Freshly dried walnuts have a moderate moisture content and are more thoroughly separated from the inner membrane, making it easier to peel off intact kernels than walnuts that are excessively dry or damp. If warm water soaking or low-temperature baking in an oven is used for manual shell peeling, it can reduce the cracking of the nuts, but high temperatures may cause oil oxidation. Some wild walnuts or aged walnuts that have been stored for a long time may produce broken kernels during peeling due to the tight adhesion between the inner membrane and the kernels, and the actual kernel yield may be less than 50%. The walnut kernels processed by mechanical cracking usually contain a large amount of residual shell debris, which requires secondary screening to affect the net weight. If walnuts are damaged by insects or mold, the weight of the usable kernels should be calculated after removing the spoiled parts. Walnut kernels are rich in unsaturated fatty acids and vitamin E. It is recommended to store them in a sealed and refrigerated container to avoid oxidation and spoilage. Daily consumption of 10-15 grams per day can meet the nutritional needs, which can be paired with oatmeal Congee or yogurt to promote absorption. When selecting dried walnuts, choosing fruits with no shaking sound and no oil stains on the shell can improve kernel yield and food safety.
