Show Preserving Foods. A new method has been diseenvered, says an Kngllsh paper, for preserving various footl products, especially milk pnwd T, thp idea being bused upon plating the substance In a sealed vessel ves-sel or pwking case with Inert gas. so t.iat this latter prevents the usual spoiling of contents by the notion of the air. In the French patented process pro-cess the mil 'rC powder Is packed In metal boxes of convenient size, which are entirely sealetl except for n pinhole pin-hole that is left at the top. A number of such boxes are put In a chamber and the air Is exhausted by means of nn air pump. When this operation Is finished valves are opened which allow nitrogen to enter the chamber and till up the several boxes. When opening up the chamber the boxes are quickly removed and the pinhole soldered before be-fore an iipreclahle amount of air has time to enter. In this way the contents con-tents of the boxes are kept In nn atmosphere at-mosphere of Inert gas, and the process Is thus practical from an Industrial standpoint. |
