Cream Whipped By Expanding Gas (Jun, 1935)
Cream Whipped By Expanding Gas
AT THE push of a button, ordinary cream, subjected to a new process, can now be turned into whipping cream. The cream is first put up by the dairy in containers of automobile steel. Rendered air-tight by the elimination of oxygen, the container next receives an injection of nitrous oxide gas. As the housewife presses the button on the top of the small cask, the nitrous oxide expands, forcing out the cream under pressure and, through aeration, whips the product.
