Everywhere in the world, the most common sterilization for the packing of liquid is by using Hydrogen Peroxide (in layman’s terms, it is bleach). The safety standard for the usage of Hydrogen Peroxide is to monitor its residue based on parts per million (ppm).

In Summerfield, we use a new, intelligent sterilisation process from Europe that uses specific heat and water process called “Ozone Water Technology”. This state-of-the art technology does not require hydrogen peroxide, yet will sterilise our bottles effectively. That is why, there is no need to monitor hydrogen peroxide residue and we never have to worry chemical residue in our milk!
