Lunch Restaurant

In Flavoria's lunch restaurant, five intelligent lunch lines collect data on people's food choices. Each food component has its own scale, allowing customers to weigh the food they take. There are also displays above the food components that guide through the weighing process.

Data Collection at the Lunch Lines

University of Turku is responsible for the research activities and technology of the platform. In the restaurant,  data is collected on customers’ lunch choices and quantities, as well as on the plate waste that customers produce.

Customers can choose to use the My Flavoria® research app, which allows them to save the nutritional information of their meal in the app. At the same time, the data is transferred to the university for research purposes. In studies, the data is analyzed without personal information.
