Question

The objective of heating milk to about 65 degree c before homogenization is to inactivate

Answer 1

Heating milk to 72 Degree Celsius (161.6 Degree Fahrenheit) for at least 15 seconds is called Pasteurisation. This kills all disease-causing germs which may be present in milk.

The process of Pasteurisation was discovered by the French scientist Louis Pasteur in 1864.

Milk may contain harmful bacteria, which causes diseases such as TB, listeriosis etc. in humans.

The process of Pasteurisation is also used in fruit juices to destroy pathogens which may be present in it and thereby extend its shelf-life.

Pasteurization or pasteurisation is a process in which certain packaged and non-packaged foods (such as milk and fruit juice) are treated with mild heat, usually less than 100 °C (212 °F), to eliminate pathogens and extend shelf life.
