Abstract

1,005,793. Stabilizing heat-sensitive liquids. UNION CARBIDE CORPORATION. Dec. 19, 1962, No. 42223/64. Divided out of 1,005,792. Drawings to Specification. Heading A2D. A heat-sensitive material in liquid form such as fruit or vegetable juice, beer, wine, coffee, milk, or resin or pharmateutical (antibiotic) in liquid form, is stabilized by subjecting it to a first stripping operation wherein an inert gas such as nitrogen, argon, hydrogen, helium or carbon dioxide, is passed through the material to displace substantially all the dissolved ogygen, increasing the temperature of the stripped material, removing volatile essence from the material by subjecting it to a second stripping operation, stabilizing the material from which the essence has been removed by increasing the temperature of the material, and then combining the essence and the stabilized material, the essence and the material being continuously maintained under non-oxydizing conditions throughout all process steps subsequent to the oxygen removal step. In preferred procedure the oxygen content of the material after the first stripping operation is to be less than 0.4 part per million, the temperature to which the material is heated after the first stripping operation is no higher than 88‹C., the material, after its stabilization by heating, is rapidly cooled before re-combining it with the essence, and the removed essence is recovered by introducing it into a body of stabilized material of substantially the same composition as that of the material from which the essence has been removed.
