== Ingredients ==
 +
A product is to a large extent defined by the ingredients that have been used to create. These ingredients define to a large extent the category.
 +
 +
=== Missing ingredients ===
 +
The listed ingredients do not always correspond to the product:
 +
 +
* the listing of ''water'' implies concentrated apple juice and in turn ''apple juice from concentrate;''
 +
* It is impossible to detect the occurrence of ''pure apple juice'' AND ''apple juice from concentrate'' at the same time;
 +
* cider seems to imply the ingredient alcohol. In the use it is also a type of apple;
 +
 +
=== Inventory ===
 +
Most common ingredients tags are:
 +
 +
* pure apple juice
 +
* apple juice from concentrate
 +
* water, need to rehydrate the apple concentrate
 +
* ascorbic acid for vitamin C
 +
* potassium sorbate as a source of potassium and preservative
 +
* malic acid as a preservative
 +
* citric acid as a preservative
 +
* calcium lactate
 +
* flavouring
 +
* carbon dioxide

=== Recipes ===
 +
Often one or more ingredients are used to create a product. This is a recipe. In order to analyse these recipes, the products with ingredients were selected (1627 products) ([https://mirabelle.openfoodfacts.org/products?sql=select+rowid%2C+code%2C+url%2C+%0D%0Aingredients_text%2C+ingredients_tags%2C+ingredients_analysis_tags%0D%0Afrom+%5Ball%5D%0D%0Awhere+categories_tags+like+%22%25apple-juices%25%22+and+ingredients_tags+%21%3D+%22%22%0D%0A Mirabelle download]). A set analysis (all juices with ingredients) using [https://upset.multinet.app/?workspace=OFF&table=AppleJuices UpSet], gives the following main recipes:
 +
* pure apple juices (only) (37%);
 +
* apple juices from concentrate (only) (14%)
 +
* pure apple juices  + vitamin C (5%)
 +
* apple juices from concentrate + vitamin C (5%)
 +
* apple juices with flavouring (3%)
 +
* apple juices with preservatives (2%)
 +
 +
=== Conclusion ===
 +
401 products did not contain normalised ingredients, either the data is incorrect or the values are missing in the ingredients taxonomy. A lot of cleanup is still required.
 +
 +
The wrong main language introduces quite some errors as the ingredients can not be parsed;
