The category Walnuts describes the edible seed of any tree of the genus Juglans (family Juglandaceae), particularly the Persian or English walnut, Juglans regia. The category has been subdivided into Fresh walnuts, which still have their shell, and shelled walnuts, without their shell. Any product with additional ingredients used as extra taste (chocolate, sugar or spices), should be put in another category.
Product names
The product names should contain the word Walnut or something related. Analysing these product names might help to find wrongly classified products or identify new subcategories. This should be done for each language. A word cloud gives a first impression.

Nutrition score
The nutrition score varies between -6 to 15. Most of the products above 5 do not take into account the percentage of nuts in the calculation. If the amount of fiber is missing from the table, the Nutrition score is to large and should be corrected by subtracting 5 points.
The median Nutriscore:

Generic errors
Superfluous categories
Only the categories that belong to the parents should be present as category. Checking the categories list might help finding wrong one.
Categorisation errors
- Single ingredient check:
- Fresh walnuts should only contain the ingredient Walnut;
- Walnut kernels should only contain the ingredient Walnut;
- Opposites:
- Fresh walnuts and Walnut kernels should not be assigned simultaneously;
- Oneside opposites(these are categories which are incompatible and which are often due to adding an ingredient as a category):
- Mixed nuts - to suppress adding all the different nuts in mixed nuts;
- Nut bars - to suppress walnuts in nut bar error;
- Chocolate covered nuts - to suppress chocolate covered nuts;
- Dried plant based foods - to suppress any dried fruit;
Nutritional errors
- Energy envelope check
- Fat envelope check
- Saturated fat envelope check
- Carbohydrates envelope check
- Sugars envelope check
- Fiber envelope check
- Proteins envelope check
- Salt envelope check
Sales format
Walnuts are sold by:
- package - pre-packed in the nuts aisles;
- weight - in the bulk aisles;
Issues
It is possible to add categories for walnut flours, salted walnuts and roasted walnuts, but these contain very few products.
