By the year 1999, most liquid products were heat treated in a continuous Gebilde where heat can be applied using a plate heat exchanger or the direct or indirect use of hot water and steam.

As a result of the unsuitability of microbiological techniques, milk pasteurization efficacy is typically monitored by checking for the presence of alkaline phosphatase, which is denatured by pasteurization. Destruction of alkaline phosphatase ensures the destruction of common milk pathogens.

Shell and tube heat exchangers are designed for the pasteurization of foods that are non-Newtonian fluids, such as dairy products, tomato ketchup and baby foods.

The process is named after the French microbiologist Louis Pasteur whose research hinein the 1860s demonstrated that thermal processing would deactivate unwanted microorganisms rein wine.

General overview of the pasteurization process. The milk starts at the left and enters the piping with functioning enzymes that, when heat-treated, become denatured and stop functioning.

As a precaution, modern HTST pasteurization processes must be designed with flow-Tarif restriction as well as divert valves which ensure that the milk is heated evenly and that no parte of the milk is subject to a shorter time or a lower temperature.

Proces pasterizace in abhängigkeit založen na tepelném opracovánitrogeniumí potravin a na poměru teploty a času po kterou jsou potraviny této teplotě vystaveny:

A tube heat exchanger is made up of concentric stainless steel tubes. Food passes through the inner tube or tubes, while the heating/cooling medium is circulated through the outer tube.

pasteurization, heat-treatment process that destroys pathogenic microorganisms rein certain foods and beverages. It is named for the French scientist Louis Pasteur, who in the 1860s demonstrated that abnormal fermentation of wine and beer could be prevented by heating the beverages get more info to about 57 °C (135 °F) for a few minutes.

Pasteurization is a mild heat treatment of liquid foods (both packaged and unpackaged) where products are typically heated to below 100 °Kohlenstoff. The heat treatment and cooling process are designed to inhibit a L change of the product.

Pasteurization may result rein some textural loss as a result of enzymatic and non-enzymatic transformations rein the structure of pectin if the processing temperatures are too high as a result.

A plate heat exchanger is composed of many thin vertical stainless steel plates that separate the liquid from the heating or cooling medium. Scraped-surface heat exchangers contain an inner rotating shaft having spring-loaded blades that serve to scrape away any highly viscous material that accumulates on the wall of the tube.[38]
