is-vegan

Is-Vegan helps you to find out which food ingredients are vegan / non-vegan. It can answer that on 1 ingredient or on a list of ingredients. It uses a 850+ entries list of non-vegan ingredients.

How to use?

Why?

We are aware that 'veganism' and the definition of it can be a hot topic. We created the non-vegan list keeping in mind that veganism in dietary terms, it denotes the practice of dispensing with all products derived wholly or partly from animals.

Our first step is the approach to help people understand, which products, and where applicable its ingredients, do not involve, or have involved, the use of any animal product, by-product or derivative. It is not driven about any vegan lifestyle choice or stereotype.
We welcome and appreciate any help and concerence regarding the nonvegan/canbevegan list.

Currently we are unfortunatly not adressing any other forms of exploitation of, and cruelty to, animals for clothing, cosmetics or any other purpose.

Thank you all for your comments, we appreciate the discussion, as we grow and learn from your input.

Updating and translating the lists

The canbevegan and nonvegan English lists are located in the i18n/en directory. The ingredients in these English lists are sorted in alphabetical order.

The lists' translations are located in the corresponding language directory under i18n. The ingredients in these Non-English lists are not sorted in alphabetical order, instead they maintain the order of the English lists.
So if, for example, the "biotin" ingredient is positioned at line 16 in the English canbevegan list, then its corresponding translation "biotina" in the Italian canbevegan list should also be positioned at line 16.
If the "bacon" ingredient is positioned at line 49 in the Enlgish nonvegan list, then its corresponding translation "pancetta" in the Italian nonvegan list should also be positioned at line 49.

Steps to add a new ingredient to the lists

1. Add the ingredient to the canbevegan or nonvegan English list, ensuring that the list alphabetical order is preserved.
2. Add the translated ingredient to each of the existing Non-English lists at the same line number as the ingredient appears in the corresponding English list.

Steps to translate the lists to a new language

1. Create a directory with the two-letter code (ISO 639-1) of the new language.
2. Translate the English lists to the new language and save these to newly created list files under the new language directory. Ensure that the ingredients in each of these new list files appear in the same order as in the corresponding English list.

Thanks for translating the lists to italian
