Abstract: A method of sterilizing a liquid milk based product comprises indirect preheating of the product and final heating to a sterilization temperature 140-150 DEG C by direct steam injection. The product is cooled by so called flash-cooling at which steam corresponding to the added amount of steam is evaporated and the product is further cooled by indirect cooling. It is now proposed that the product prior to the flash-cooling is cooled from the sterilization temperature of 140-150 DEG C to a temperature in the range 90-120 DEG C in an indirect, first cooling step after which the product is cooled by flash-cooling to a temperature of 70-85 DEG C. The arrangement for sterilization comprises a balance vessel (1) connected to an indirectly working first heat exchanger (4) for heating of the milk based product. A steam injection nozzle (6) is arranged in a pipeline leading from the heat exchanger (4). After the steam injection nozzle (6) there is a holding section (8) and a vacuum vessel (10) in which the product is cooled by flash-cooling. A further indirectly working heat exchanger (9) for cooling of the product is connected between the holding section (8) and the vacuum vessel (10).

Inventor: REZAIE ALIREZA
IPC: C12N9/64
Filed: 1992-12-29
Abstract: A method is disclosed to make any protein in a form that can be isolated rapidly from a solution using a specific monoclonal antibody designated "HPC-4". It has now been determined that it is possible to form a fusion protein of the epitope with a protein to be isolated, and isolate the protein using HPC-4-based affinity chromatography. In the preferred embodiment, a specific protease cleavage site is inserted between the epitope and the protein so that the epitope can be easily removed from the isolated protein. In an example, a functionally active soluble tissue factor including the twelve amino acid epitope recognized in. combination with calcium by HPC-4 and a factor Xa cleavage site was expressed from a vector inserted into a procaryotic expression system. The recombinant tissue factor can be rapidly isolated in a single chromatographic step using the HPC-4 monoclonal antibody immobilized on a suitable substrate. Once isolated, the Protein C epitope is removed by cleavage with factor Xa, leaving the functionally active, soluble tissue factor.
