A dough-based food product, an apparatus and method for production thereof. A food product matrix to be foamed includes a proportion of a starch-containing raw material and a proportion of water. Gas that has been dissolved or is to be dissolved is introduced into the food product matrix to be foamed. The gas is dissolved under pressure in the food product matrix to be foamed. Gas bubbles are formed by expansion and increasing the volume with a resulting reduction in density of the dough as a result of bubble growth for formation of a foamed food product matrix of the food product to be produced. The foam is then stabilized. Gas is introduced into and dissolved in the aqueous component of the food product matrix to be foamed in a subcritical state below the critical point and at a pressure of 10 bar≤p<gas critical pressure.

The invention relates to a process and to a device for producing a pore-containing foodstuff, the matrix of which enclosing the pores contains starch. The process is characterized in that the dough is flowable, is admixed with pressure gas and is expanded through a nozzle into an adjacent flow-through channel so that the raw dough containing pressure gas foams in the flow-through channel. For warming of the foamed dough the flow-through channel has a section which is directly adjacent and has at least two electrodes arranged on its circumference for applying current to the foamed dough.

The invention relates to a method, a control and/or regulating device, a device and products as well as the use of such products. It is shown how gas-foamed products are manufactured from doughs or from pastes in an elongated process space and how the static pressure required for the gas dissolution is maintained in the process space up to the outlet opening and the foaming in the dough or in the paste is not initiated in a targeted manner under predetermined process conditions until the product exits from a metering valve device connected downstream of the process space and the pressure is reduced.
