Apple juice products often have labels or other claims on the packaging.
 
=== Labels ===
 
=== Labels ===
 +
Several labels can currently been found ([https://world.openfoodfacts.org/category/apple-juices/labels/ the list]). Some are useful, but other unnecessary. A quick look at some labels:
 +
* ''organic'' (and variants) has 638 products;
 +
* ''vegan'' (and thus vegetarian) has 109 products. The filtering process might not be vegan, as [https://en.wikipedia.org/wiki/Isinglass isenglass] can be used;
 +
* ''no added sugar'' (326 products). The EU legislation does not allow any added sugar, so it is not really necessary. But this label might be useful for other countries.
 +
* ''no preservatives'' (245 products) - preservatives are allowed by EU legislation (think antioxidants like malic acid, citric acid or ascorbic acid), so it might fe found in the ingredients list. This label could be added if these ingredients are not on the package.
 +
* ''no colorings'' (151 products) - are there products that do have colorings?
 +
* ''EU Agriculture'' (and variants) (103 products) - should also be in the origin field.
 +
* ''pure juice'' (70 products) - this is not a label
 +
* ''no additives'' (51 products) - This seems the same as pure juice. This can be added based on the ingredient list?
 +
* ''Demeter'' (34 products) - this is not a label, but a brand?
 +
* ''low or no sugar'' (27 products) - these seem be wrongly labelled and should read ''no added sugar''.
 +
* ''no gluten'' (25 products) - seems unnecessary.

* when should something be added as a label, an adjective of an ingredient, or even a dedicated category?
