The cold chain is an essential element
in the supply of fresh and safe milk.
The eight step procedure is a critical process which covers the supply of milk from cow to consumer. The main aim of the cold chain is to keep bacterial contamination to minimum levels and provide consumers with safe fresh milk. Temperature is a main contributor to bacterial contamination, so strict controls have been put in place to keep the milk at a constant temperature of four degrees centigrade (+4ºC) throughout the whole process.
In the first stage, after the cows have been milked under hygienic conditions, the raw milk output is examined by technicians at the processing plant. This ensures that the milk is of the required quality and standards.
The milk is then stored in silos at a constant temperature of +4ºC before starting the processing procedure by
being treated by pasteurisation. The pasteurisation process involves the milk being heat treated to destroy any harmful bacteria present in the raw milk.
The milk is then subjected to homogenisation which is a mechanical process where the milk fat is evenly distributed throughout the milk. Homogenisation gives milk a creamy taste and stops the fat from collecting along the top and sides of the bottle
as cream.
After being treated by pasteurisation and homogenisation, the milk is packaged or formulated into other dairy products prior to being stored for distribution from the dairy to the sales depots.
The entire fleet of Al Ain Dairy vehicles is fitted with cooling units to enable the distribution of milk from the dairy to the sales depots and in turn to the retailers at the required temperature.
Al Ain Dairy salesmen regularly
monitor that retailers conform to the requirements of the cold chain by checking and inspecting the temperatures of the cold storage units used to
display products to consumers and remedial action is taken in the event
of non-conformance.
The cold chain process ultimately provides the consumer assurance and confidence that they are purchasing the freshest milk that has been produced, stored and distributed under the most hygienic and controlled conditions possible.
