The category Almonds describes are the edible seeds of the almond tree (Prunus amygdalus). There are many varieties, like Marcona, Nonpareil, etc.

Almonds grow with the outer hull. Once removed an inner shell remains (Unshelled almonds), which can be removed in turn (Shelled almonds). Shelled almonds still have a dark sheetcoat, which can be removed as well (Blanched almonds).

Both shelled and blanched almonds can be roasted (with oil or dry) and/or salted.

Almonds consist of 53% fat, 10% carbohydrates, 11% fiber and 21% proteins. Almonds are classed as Nutriscore A.

The category contains 3650 products on 26 November 2024.

Product names

The product names should contain the word Almonds 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.

Categorisation

Super-categories

Ingredients-based super categories

The super (parent) categories of Almonds is:

Sub-categories

These subcategories are orthogonal: a product can be assigned one or more of the subcategories. This category has several subcategories:

Convenience categories

Convenience categories are categories that can be expressed in terms of two and more facets, but exist to help the user entering categories

Nutritional information

Almonds nutritional profile

The plots seem to suggest that there are two nutritional subcategories.

  • Vipd = the interpercentile distance (V90% - V10%)
  • Vlower = V10% - Vipd
  • Vupper = V90% + Vipd

The distribution of proteins seem to suggest a subcategory (see the violin plots).

Nutrition score

The Nutrition Score suggests varies between C (146 products) and D (186 products). It is not clear whether Pine nuts should be taken into account as nuts. This would move all a score down. The median Nutriscore is Dark Green (A) if it counts as Nuts.

Median nutritional values

The two pie charts show which macronutrients make up Almonds (the missing is assumed to be water) and the origin of the energy in Almonds.

Comparing categories

There seem to be two subcategories when looking at the nutritional profiel, needs more investigation. There are a few theories:

  • Roasted almonds have lost some water (only 5% available) and thus should have higher fractions of the other nutrients;
  • Roasted almonds that have been baked in oil, should have a higher fat fraction;
  • Blanched almonds should have less fiber than almonds with the skin;

It is not yet possible to determine this as not many products have been assigned to the correct subcategories. With what we have now we cannot confirm the roasted almonds theories. The almond flakes, which are mostly blanched, seem to have 1% less fiber.

Sales format

The sales format might depend on the shop. All are sold by package.

Sold by weight are: - Shelled, non-blanched, unroasted almonds; - Shelled, non-blanched, roasted almonds;

Hunger Game

Classify products which Robotoff has identify as category Almonds:

Extracting data

  • Nutritional values: products for which the nutritional values can be extracted from the associated image;
  • Ingredients: products for which the ingredients can be extracted from the associated image;

Superfluous categories

Only the categories that belong to the parents should be present as category. Checking the categories list might help finding wrong one.

Issues

  • Should the Dried fruits be a parent? In some languages they seem to do that.
  • There are some possible new categories with very few products at the moment. There might be more products, but there is no way to track them down. These will be kept in the hierarchy, but commented out:
    • de:Mandelstifte
    • de:Mandelscheiben
    • fr:Amandes hachées
    • Bitter Almonds
    • Sweet almonds
    • Unshelled almonds
  • Almond meal is a bit strange. Normally these are call Ground almonds or Almond powders. These are linked to Nut flours. Not sure why this is useful.
  • The category Almonds should be called Unflavoured almonds. The approach is now that any almond with some flavour is moved to Flavoured almonds. At some stage we can do some renaming.
