Walnut sorting according to their internal quality: primary results.

Author(s) : CROCHON M., GUIZARD C., STEINMETZ V., BELLON V.

Summary

Empty walnuts must be rejected from marketed sets. At present they are removed by an air jet. But this technique still gives 6% error, whereas the maximum allowed error is 2%. The authors have tested 3 methods to sort walnuts: weight, density and X-ray transmission. The results of these methods are compared to a human assessment of walnut quality into 5 classes. These methods could be improved to meet grocery store requirements.
