It all began over 100 years ago with a little packet of baking powder called "Backin". Created by chemist Dr. Oetker in Bielefeld, it became a classic brand. The family business has since developed from the baking and custard powder factory into a globally active, diversified corporate group. The historical custard powder factory at the company headquarters have now been redesigned by the architectural design offices of Ackermann & Raff into "Dr. Oetker Welt" - a place that provides a unique experience to the visitor with its museum, exhibitions, lecture kitchens and test kitchens. The designers opened up the U-shaped old building on the sides around the inner courtyard and added a glazed hall. This provides access to all levels and makes the internal procedures transparent.
