Main description
The ESL milk (with a shelf life of 3-6 months at am bient temperature) is produced by UHT milk. A typical tem perature/time combination of UHT process which operates at high processing temperatures is 135 to 145° C holding for example 4 seconds.
Aseptic packaging system fills the sterile milk into aseptic cartons, bottles and plastic pouches which have been sterilized by heat, chemicals or radiation prior to the packaging.
Extended shelf life milk is achieved by
1. Sterilisation of the products before flling
2. Sterilisation of packaging materials or containers and closures before flling
3. Sterilisation of aseptic installations before operation (UHT unit, lines for products, sterile air and gases, fller and relevant machine zones).
4. Maintaining sterility in this total system during operation; sterilization of all media entering the system, like air, gases, sterile water.
5. Production of hermetic packages
