Based on our work on Food Allergens and Product Master Databases, we developed a barcode scanning feedback applications to enable Swiss consumers to receive tailored allergen feedback based on ingredient data of purchased products. We assess the impact of gamification, tailoring of information on the intention forming and ultimately behaviour on these novel feedback apps.

Our product database which is used as basis for this products currently contains around 30 000 products including each product’s image, size, text description, nutrient and category data, and is constantly being extended.

Each of our apps is a publicly available mobile application in which users will become able to scan product items and the app will then compile a quantitative assessment of the user’s dietary history and recommend substitutes with a relative high, positive impact to the user. The Swiss Society for Nutrition supports our research on purchase feedback applications.
