Synonyms for pasteurizing include decontaminating, disinfecting, heating, purifying, sanitising, sanitizing, sterilising, sterilizing, cleaning and fumigating. Pasteurization or pasteurisation is a process in which packaged and non-packaged foods (such as milk and fruit juice) are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life. A tube heat exchanger is made up of concentric stainless steel tubes. [54], Other thermal and non-thermal processes have been developed to pasteurize foods as a way of reducing the effects on nutritional and sensory characteristics of foods and preventing degradation of heat-labile nutrients. High-temperature short-time (HTST) pasteurization, such as that used for milk (71.5 °C (160.7 °F) for 15 seconds) ensures safety of milk and provides a refrigerated shelf life of approximately two weeks. [24] Because tuberculosis has a long incubation period in humans, it was difficult to link unpasteurized milk consumption with the disease.

Parameters also take into account nutritional and sensory qualities that are sensitive to heat. Pasteurization of milk was suggested by Franz von Soxhlet in 1886. Do you know what they mean? Before pasteurization milk is homogenized to emulsify its fat and water-soluble components, which results in the pasteurized milk having a whiter appearance compared to raw milk. The mean log10 reductions and temperatures of inactivation of the major milk-borne pathogens during a 15-second treatment are: (A log10 reduction between 6 and 7 means that 1 bacterium out of 1 million (106) to 10 million (107) bacteria survive the treatment.

The process was named after the French microbiologist, Louis Pasteur, whose research in the 1860s demonstrated that thermal processing would deactivate unwanted microorganisms in wine. Direct microbiological techniques are the ultimate measurement of pathogen contamination, but these are costly and time-consuming, which means that products have a reduced shelf-life by the time pasteurization is verified. Copyright © 2002, 2001, 1995 by Houghton Mifflin Company. [1] For vegetable products, color degradation is dependent on the temperature conditions and the duration of heating.

Apart from meta-analysis, it is not possible to draw conclusions about the effect of pasteurization on vitamins A, B12, and E based merely on consultation of the vast literature available. [54], Pasteurization may result in some textural loss as a result of enzymatic and non-enzymatic transformations in the structure of pectin if the processing temperatures are too high as a result. Vitamin B2 is typically found in bovine milk at concentrations of 1.83 mg/liter. [52][51] A significant decrease in vitamin B2 concentrations was found after pasteurization. [1], Most liquid foods are pasteurized using continuous systems that have a heating zone, hold tube, and cooling zone, after which the product is filled into the package.
