The war affected Fazer’s operations in many ways. The production of chocolate was stopped in 1940 and the amount of sugar and fat in biscuits was limited. Fazer’s biscuit factory in Hanko was evacuated to Helsinki and Fazer’s production units produced macaroni for the Defence Forces.

During the war, import of sugar and cocoa beans substantially reduced, so substitute products had to be found. A product called “Ravitol” was made from beetroot syrup and roasted beans – its taste “vaguely resembled cocoa”. Other war-time products included lingonberry marmalade, apple and rowan berry marmalade, carrot and apple marmalade and different sorts of biscuits. The production of liquorice was stopped at times during the war when some of the raw materials were handed over to medical services. In 1947, inspired by the Paris peace treaty, Fazer launched the Pax pastilles. In 1949, the rationing of chocolate was terminated and producing the old products could be resumed.
