The invention relates to a method and associated database structure for tracking in production in a plant for liquid foods. Each production unit in the plant is allocated a unit identity which is registered in a database. Each production unit can be a source or a destination. Each material quantity which is included in the production is allocated a work identity which is registered in the database. A material quantity includes a given product of a given quantity. Each event in the plant is registered in the database. The registration takes place as a transport from a source to a destination, with references to the unit identities of both the source and the destination.
