Why is immediate cooling is necessary after pasteurisation?
Pasteurisation does not kill all bacteria in the milk. Some bacteria are not killed in the heating process and will start to multiply again after pasteurisation. Cooling after pasteurisation is needed in order to limit the amount of bacterial growth that occurs. Bacteria reproduce very slowly in cold conditions, but very quickly in hot conditions. Cooling is the only preservative that is used after pasteurisation.
What agricultural products were used in pasteurisation?
Milk
What is phosphatase test in milk?
The phosphatase test in milk measures the amount of phosphatase enzyme in the milk. The phosphatase enzyme should be inactivated by pasteurisation. If the phosphatase test is not negative, there is a problem with pasteurisation or recontamination with unpasteurised milk.
Does the law in Australia require milk pasteurisation?
Yes
How does pasteurisation make milk last longer?

Hoy do bacteria help change mili into yogurt?
What is the procedure for pasteurising milk?
There are a couple of methods for pasteurisation: 1. Batch pasteurisation In this method milk is heated in a tub while stirring to not less than 63°C for at least 30min. This is followed by cooling within 30min to below 5°C. This method is less commonly used today. 2. High temperature short time pasteurisation Using a continuous system (stainless steel pipelines) milk is pumped through heat exchangers for pasteurisation at 72°C for 15 seconds. After this it is cooled down to below 5°C quickly through heat exchangers. The more the temperature is increased, the less time is needed for the pasteurisation to be effective. After pasteurisation, the standard test to see if it was effective is the phosphatase test.
Why is salt put in 1 percent milk?
No salt is added in the processing of milk. The process would be as follows: separation of cream and milk, adding back 1% milk fat, homogenisation and pasteurisation.
What is the chemical formula for pasteurized milk?
Milk is not a chemical compound it is amixture of many compounds. Pasteurisation is a process that heats milk to kill bacteria without affecting the properties of the milk too much.
