Frequently Asked Questions

1. Can I buy products on your website?

Unfortunately not, our website is just an information portal for food products and no online shop. WikiFood builds up a volunteer network of food product users that fill up our database. WikiFood wants to offer the possibility to get information about interesting food products and to prepare the purchase. Please contact the manufacturer directly to find out if a specific product is available in your country.

2. I'm very interested in your website. Can I see the information in English too?

Our web page is available in English, French and German. At the moment most of the content of this website is in German. But you can change the language in the upper right corner. Please click on en to see the website in English. Content that was inserted by users like comments or ingredient list can not be translated.

3. Why should I upload product pictures?

With the help of these pictures (if they are captured properly) barcodes, ingredient lists and other notes can be validated if necessary. Nobody can exclude typing errors at all. Checking these pictures increases data quality.

4. Why do I have to capture the product pictures myself? Why can't I use pictures found in the web?

Analogue to Wikipedia we do not want to breach the copyright. Most of the pictures on the web are under copyright and can not be reused in projects like WikiFood.

5. Why should I type in the date of expiry of food products?

Food producers can modify the ingredients of their products without highlighting these changes. So consumers can not see the production batch of products directly. With the date of expiry we have a reference point that can be an indicator why an ingredient list has changed.

6. We are a food producer and we want to publish our products on WikiFood. But we do not want that this information can be changed by other users. Is this possible?

We are very pleased that you are interested in publishing your products on WikiFood. We offer a special service for data entry to food producers (please see next question). If you use this service, every user can see your products but can not modify the product information.

7. We are a food producer and we want to publish our products on WikiFood. Do we have to insert all data via the web front-end?

We offer a special service for data entry to food producers. Please use the contact form to discuss the next steps.

8. Why to I have to accept the general conditions of use before I can search the database?

Because of legal reasons unregistered users have to accept our general conditions of use before they can search in our database. We as operator of WikiFood have to ensure that every user has understood the tasks and service capabilities of WikiFood. Registered users do not have to accept our general conditions of use before searching because they already have accepted our general conditions of use during the registration process.

9. I'm registered and logged in on WikiFood but I can't edit special products if I've found an error.

Products that are provided directly by food producers or other databases can not be modified by other users. But you have the possibility to contact the food producer or database provider directly to inform him about errors. So he can check and correct the product information.
The notification of food producers and database providers is anonymous. To avoid misuse the WikiFood team knows the author of the notification.

10. Why can't I see all information of a product?

Because of legal reasons unregistered users can not see all information of a product. They have to accept our general conditions of use to see all available information. We as operator of WikiFood have to ensure that every user has understood the tasks and service capabilities of WikiFood.

11. How can I use the Search Filter?

Each registered user of WikiFood has the possibility to create his own Search Filter in the Member Center. There he can select the ingredients to avoid. By activating the Search Filter the user only sees products that do not contain any of these ingredients. If the user is logged in and the Search Filter is inactive than incompatible products are highlighted in gray. In the detail view these products are marked with the message "contains unwanted ingredients" in the upper right corner.

12. Although activating the Search Filter I find products with unwanted ingredients?

The result of the Search Filter depends on the data quality of each entry. Only products where the allergens are entered can be filtered. Help us to correct these entries.

13. Your page is not displayed correctly in my browser?

Our website is optimised for Mozilla Firefox but all other modern browsers should display it correctly. If you use an older version of an browser (e.g. Internet Explorer 6) you should upgrade to the latest version.

14. Traffic light rating system

The Traffic light rating system simply indicates the content of fat, saturated fats, sugar and salt. Green indicates a low, yellow a medium and red a high percentage of the ingredient. WikiFood uses the values provided by the British Food Standards Agency (FSA) to rate the products. The values are based on 100 gram respectively 100 millilitre.
