[33], The shelf life of refrigerated pasteurized milk is greater than that of raw milk. In acidic foods (pH <4.6), such as fruit juice and beer, the heat treatments are designed to inactivate enzymes (pectin methylesterase and polygalacturonase in fruit juices) and destroy spoilage microbes (yeast and lactobacillus).

He placed the food in glass jars, sealed them with cork and sealing wax and placed them in boiling water. the Reynolds number should be sufficiently high.” The point about turbulent flow is important because simplistic laboratory studies of heat inactivation that use test tubes, without flow, will have less bacterial inactivation than larger-scale experiments that seek to replicate conditions of commercial pasteurization. (of IV. : Milk is pasteurized to safeguard humans from becoming infected with M.

[4], In regards to color, the pasteurization process does not have much effect on pigments such as chlorophylls, anthocyanins and carotenoids in plants and animal tissues. In ultra-high-temperature (UHT) pasteurization, milk is pasteurized at 135 °C (275 °F) for 1–2 seconds, which provides the same level of safety, but along with the packaging, extends shelf life to three months under refrigeration.[39]. 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.

Pasteurization of milk was suggested by Franz von Soxhlet in 1886. [11], Appert's method was so simple and workable that it quickly became widespread. [1][2] Since pasteurization is not sterilization, and does not kill spores, a second "double" pasteurization will extend the quality by killing spores that have germinated. [7], A less aggressive method was developed by French chemist Louis Pasteur during an 1864[13] summer holiday in Arbois. to expose (a food, as milk, cheese, yogurt, beer, or wine) to an elevated temperature for a period of time sufficient to destroy certain microorganisms, as those that can produce disease or cause spoilage or undesirable fermentation of food, without radically altering taste or quality. For all practical purposes, these conditions were adequate for destroying almost all yeasts, molds, and common spoilage bacteria and also for ensuring adequate destruction of common pathogenic, heat-resistant organisms.
