摘要：
Method and system for controlling the density to a predetermined level of an edible aerated foodstuff product during the preparation thereof. A density measurement is acquired on the aerated product at a location sufficiently downstream of a shearing unit used to form the aerated material such that the product is in an equilibrated state. Consequently an adjustment can be made in the introduction rate of aeration gas at a location upstream of the shearing unit which is calculated to reduce any difference between the predetermined an measured product densities in a precise and reliable manner. Also, injection gas of reduced solubility may be used so that product density can reach equilibrium sooner. Upstream disturbances in the density of a formulation starter material also may be monitored and countered by adjustments made in the gas flow rate to assist in maintaining a desired product density.
