Milk
Always available in white
Milk is becoming more popular in developed countries too where enrichment, flavours or removal of lactose all add value. These products are commonly found on sale alongside more traditional types of milk.
UHT or Pasteurised milk?
The
pasteurisation process involves heating milk to 72-75 degrees Celsius with a holding time of 15-20 seconds before it is cooled. Along with correct cooling, pasteurisation will supply milk with longer shelf life. With proper chilled distribution, pasteurised milk has a shelf life of 5-15 days.
Using
UHT treatment, liquid food products are exposed to brief, intense heating to temperatures in the range of 135 to 140 degrees Celsius. UHT treatment is a continuous process which takes place in a closed system that prevents the product from being contaminated by airborne micro-organisms.
The product passes through
heating and cooling stages in quick succession. Aseptic filling is an integral part of the process that avoids re-infection. The end result is a product that can be conserved for around six months without refrigeration.
