At what temperature does pasteurization occur?
The most common method of pasteurization in the United States today is High Temperature Short Time (HTST) pasteurization, which uses metal plates and hot water to raise milk temperatures to at least 161° F for not less than 15 seconds, followed by rapid cooling.
How is pasteurization done?
How is milk pasteurized? In most milk processing plants, chilled raw milk is heated by passing it between heated stainless steel plates until it reaches 161° F. It’s then held at that temperature for at least 15 seconds before it’s quickly cooled back to its original temperature of 39° F.
What is the difference between heating and pasteurization?
Sterilization is a destruction of all microorganisms and their spores. Pasteurization is a process that kills the pathogenic bacteria by heating to a certain temperature for a set period of time. Pasteurization only destroys the vegetative forms of the bacteria.
What 3 vitamins are destroyed from pasteurization?
During pasteurization, more than 50% of vitamin C is lost. The primary cofactors, enzymes and proteins that assist in the absorption of folate, B12, B6, and iron are also destroyed with pasteurization.
What are the 2 types of pasteurization?
There are two kinds of pasteurization:
- High Temperature Short Time (HTST, or simply “pasteurized”)
- Ultra-High Temperature (UHT, or ultra-pasteurized)
Why milk pasteurization is important?
“Pasteurized Milk” Explained First developed by Louis Pasteur in 1864, pasteurization kills harmful organisms responsible for such diseases as listeriosis, typhoid fever, tuberculosis, diphtheria, Q fever, and brucellosis.
Is boiling milk the same as pasteurization?
Boiling is not the same as pasteurization, although they’re similar. Pasteurization in the United States involves heating milk up to about 160°F for the purpose of killing bacteria that could make you sick.
Does pasteurization destroy nutrients in juice?
Pasteurization is the process of treating juice, milk and other foods to kill harmful germs, usually by heating. Although the levels of certain nutrients in juice may decrease with pasteurization, the final product retains most of the original nutritional value.
Does pasteurization destroy B12?
The destruction of B12 by pasteurization could be disastrous for these folks. Pasteurization destroys the enzymes and carrier proteins needed to absorb calcium, folate, B12, B6, vitamins A and D, iron and many other minerals.
