Category/Nuts/Pistachios

The category Pistachio nuts describes the edible seed of the tree Pistacia Vera. The nuts are sold with or without shell and can be roasted and salted as well. Shelled nuts can be broken in pieces (hacked), ground or made into a nut butter.

Pistachios are also sold flavoured with Chili, Pepper, Lime, etc (Flavoured Pistachios). Pistachios are sold as a confectionary when coated with chocolate (Chocolate covered Pistachios) or caramelised (Caramelised pistachios). When pistachios are finely ground with added fat and sugare, it becomes a Pistachio cream like Nutella.

Quality Monitoring

Generic errors

• Data quality errors that can be detected;

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:
  • Plain pistachios should only contain the ingredient Pistachio;
• Internel opposites:
  • Plain pistachio and Pistachios(salted), Pistachios(roasted) should not be assigned simultaneously;
  • Pistachios(salted) and Pistachios(unsalted) should not be assigned simultaneously;
  • Pistachios(shelled) and Pistachios(unshelled) 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 detect adding all the different nuts in mixed nuts;
  • Chocolate covered pistachios - to detect chocolate covered nuts;

Sales format

Pecan nuts are sold by:

• package - pre-packed in the nuts aisles;
• weight - in the bulk aisles;

Issues

Quite a lot of products have issues with nutritional values. It seems due to a difference in weight used, either with or without shells.

A few other subcategories could be defined, but have few products at the moment:

• Hacked pistachios for pistachios that have been hacked into small pieces;
• Pistachio butters(100%) for pistachions that have been ground without added ingredients like sugar or oil;
• Pistachio flours for finely ground pistachios
• Dry roasted pistachios for roasted pistachios without oil.
