ABSTRACT:
The invention proposes using liquefied carbon dioxide as a separation agent for flotation and/or sedimentation separation, which is particularly suitable for separating foodstuff mixtures such as meat components, because it can be maintained in liquid phase at the freezing point of water and is inert with respect to many substances of the mixture. By controlling the pressure and/or the temperature at values of about 26 bar and -14.degree. C., the density of the separation agent can be adjusted to correspond to that of water so that water containing substances of the mixture can be readily separated.
