Wheat and wheat-rye doughs, including those modified with ingredients, were frozen at -30°C in air recording their temperature with a digital thermometer. After preliminary baking the following were determined: dough and bakery efficiency, crump mass density, bakery volume, baking, total baking loss and crust-crump ratio. The rheological assessment was made after TPA test, while organoleptic evaluation included: bakery appearance, colour, crust thickness, elasticity, crump porosity, taste and flavour.
