  • Raw hazelnuts should only contain the ingredient Hazelnuts;
• Opposites:
  • unshelled-hazelnuts and Shelled hazelnuts should not be assigned simultaneously;
  • Hazelnut powders and Hazelnuts (whole) should not be assigned simultaneously;
  • Blanched shelled hazelnuts and Shelled hazelnuts with skin should not be assigned simultaneously;
  • Raw hazelnuts and Roasted hazelnuts 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:

• • Sweet spreads - to suppress chocolate-hazelnut creams;
  • Almonds - to suppress mixed nuts;
  • Walnuts - to suppress mixed nuts;
  • Snacks - to suppress bars with hazelnut;
  • Dried fruits - to mixes with dried fruits, such as raisins;
