While there is a lot of controversy around pasteurization, the milk we can find on supermarket shelves is always pasteurized. And in many countries, it’s mandatory even for small farms to process their dairy. That’s why — no matter what side you’re on — it’s important to know all the details about the process, time and temperature for pasteurizing milk. What Is Milk Pasteurization? Every component in the line offers resistance to the flow when a liquid is forced through a pipe system. In straight pipes, the resistance is due to friction between the liquid and the walls. In bends, additional friction occurs from the liquid having to change direction. In the same way, friction, changes of direction and changes of section result in resistance in fittings, valves and processing equipment. The magnitude of this resistance is relative to the velocity of the liquid in the system. Prior to industrialization, dairy cows were kept in urban areas to limit the time between milk production and consumption, hence the risk of disease transmission via raw milk was reduced. [23] As urban densities increased and supply chains lengthened to the distance from country to city, raw milk (often days old) became recognized as a source of disease. For example, between 1912 and 1937, some 65,000 people died of tuberculosis contracted from consuming milk in England and Wales alone. [24] Because tuberculosis has a long incubation period in humans, it was difficult to link unpasteurized milk consumption with the disease. [25] In 1892, chemist Ernst Lederle experimentally inoculated milk from tuberculosis-diseased cows into guinea pigs, which caused them to develop the disease. [26] In 1910, Lederle, then in the role of Commissioner of Health, introduced mandatory pasteurization of milk in New York City. [26]

For the location of the flow diversion valve, various solutions are available to satisfy local regulations and recommendations. Below are three alternatives which are commonly utilized: What is double pasteurization?". Archived from the original on 23 April 2021 . Retrieved 25 January 2021. When changes in the composition, processing and use of the product are proposed, the necessary changes to the scheduled heat treatment should be established and a qualified person should evaluate the efficiency of The products subjected to pasteurization should show a negative alkaline phosphatase reaction immediately after the heat treatment as determined by an acceptable method. Other methods could also be used toHigh-pressure treatment: Application of high hydrostatic pressures to irreversibly damage the membranes of vegetative cells.

The milk must be heat treated in such a way that all pathogenic microorganisms are killed. A minimum temperature/holding time of 72 °C for 15 seconds must be achieved. When the relevant parameters are known, the size (dimensioning) of the heat exchanger can be calculated. In the present example, the parameters are: To keep things simpler for yourself, you can always use a milk pasteurizer that will take all the hassle away.

That’s why milk is made safe with pasteurization. These health risks are the reason many countries forbid the sale of raw dairy products. So often, both big manufacturers and small farms have to process their milk. After bulking, the chilled milk is heated to about 40°C to facilitate easy separation of butterfat during standardization. The resistance of each component in the line can be obtained from the resistance coefficient given by the manufacturer. The total resistance of the line can then be calculated by multiplying the sum of the coefficients by the square of the flow velocity and dividing the result by 2 g (g = the acceleration due to gravity = 9.81 m/s 2). Sterilization is a microbiocidal control measure that can be obtained by various heat treatments, the most common and [validated] methods being UHT (Ultra High Temperature) processing in combinationThe feed pump supplies the pasteurizer with milk from the balance tank, which provides a constant head.

Homogenization is a physical process of breaking down the milk fat globules into tiny droplets to discourage cream separation.

The pressure drop over each of the components in the line for a given flow rate can be determined in the same way. When added together, these values give the total pressure drop for the system. Higher velocities result in greater friction in the liquid itself and between the liquid and the pipe wall. Consequently, there is more mechanical treatment of the product. For each product, there is an upper velocity limit that should not be exceeded if quality demands are to be met. For milk, this velocity is about 3 m/s. a b c Jan, Awsi; Sood, Monika; Sofi, S.

Developed countries adopted milk pasteurization to prevent such disease and loss of life, and as a result milk is now considered a safer food. [27] A traditional form of pasteurization by scalding and straining of cream to increase the keeping qualities of butter was practiced in Great Britain in the 18th century and was introduced to Boston in the British Colonies by 1773, [28] although it was not widely practiced in the United States for the next 20 years. Pasteurization of milk was suggested by Franz von Soxhlet in 1886. [29] In the early 20th century, Milton Joseph Rosenau established the standards – i.e. low-temperature, slow heating at 60°C (140°F) for 20 minutes – for the pasteurization of milk [30] [31] while at the United States Marine Hospital Service, notably in his publication of The Milk Question (1912). [32] States in the U.S. soon began enacting mandatory dairy pasteurization laws, with the first in 1947, and in 1973 the U.S. federal government required pasteurization of milk used in any interstate commerce. [33]

Pasteurization carried out in a batch-process involves the heating of milk placed in a container to a certain temperature for sufficiently long time to achieve equivalent effects as in the case of the HTST process. The To save energy, heat is regenerated, i.e. the chilled milk feeding the exchangers is heated by the pasteurized milk leaving the pasteurization unit. Microfiltration: Removal of microbial cells, clumps and somatic cells by recirculation over a microfilter. Normally, a pore size of ~0.6-1.4 µm is sufficient to separate most bacteria. Synergy in combination with heat treatment. The service water is circulated by the centrifugal pump (5) via the heater (3) and the heating section of the pasteurizer. In the example in this chapter, 20 000 litres of milk per hour have to pass through pipes, fittings and processing equipment during production. The product velocity through the pipes is determined by the size of the passage, i.e. the inside diameter of the pipe. The larger the diameter, the lower the product velocity.
