It kills most of the bacteria, extending shelf life and reducing bacteria to safe levels. This is more effectively accomplished by boiling, but this has both cost and taste repercussions making pasteurization a reasonable middle ground between killing off unwanted organisms and maintaining the taste and integrity of the milk.
powdered milk tastes rough. pasteurised doesnt. powdered milk lasts up to a year. pasteurised doesnt. powdered milk needs to be mixed with water before used. pasteurised doesnt. powdered milk is basically less expensive and lasts longer but is a hassle to prepare
Pasteurisation is a heating process that is designed to kill spoilage microorganisms and pathogens.
By killing off spoilage organisms, the product will keep fresh longer since the organisms that are left first need to multiply again to be able to cause the spoilage.
The process of multiplying is slowed down by keeping the milk below 5°C (since the organisms multiply slower at a low temperature).
Well, that's why. To help it stay fresh longer. Before pasteurization (and refrigeration), everyone had to get their milk directly from the dairy every few days or it would spoil before it could be used.
It looses the taste of freshness. You can not make whipping cream out of the cream. (or out of the lovely monster juice(whispering eye)
Milk is pasteurized for preservation, killing of germs & long shelf life.
There aren't many disadvantages unless you are trying to make specific raw cheeses where the bacterial activity is needed.
It kills germs and bacteria that may be in the milk making it last longer and stopping potential disease.
Yes, All milk is pasteurised
Louis PASTEUR created pasteurised milk. that's how pasteurised milk was called pastuerisd
heat the milk
160 degrees Fahrenheit
He is the guy who invented pasteurised milk
Pasteurised milk is safe to drink all year round if the product is still within it's expiry (or sell by) date.
Louis Pasteur
I really can not think of one disadvantage to Pasteurizing milk. Taste?
There is no such thing as regular milk. Milk is either whole or separated and can be pasteurized or non pasteurised. Better to go to the feed store and get powdered milk for calves. It usually has other additives to help the calf get stronger.
Louis Pasteur, who else?
Regardless of treatment/origin it's always better to boil milk.
A large proportion cheeses are pasteurised. Some cheeses like Cheddar you can get in both pasteurised and unpasteurised form.
