sterilised milk is treated with much higher temperatures to destroy almost all of the bacteria in it
the milk is heated to around 50 degrees, homogenised and then poured into glass bottles which are closed with an airtight seal
the filled bottles are carried on a conveyor belt through a steam chamber where they are heated to a temperature between 110 to 130 degrees for approximately 10 to 30 minutes
the bottles are then cooled and ready for sale
unopened bottles or cartons of sterilised milk will keep for approximately 6 months without the need for refrigeration
once opened, sterilised milk must be treated as fresh milk and used within 5 days
the sterilisation process causes a change to both the taste and colour and also reduces some of the water soluble B and C vitamins
