Microfiltration is the most innovative and modern milk production technology on the Polish market, a determinant of quality and safety of a product. COLD MILK is the first milk in our country manufactured with the use of this technology. COLD MILK is made by subjecting milk to the microfiltration process, which is mechanical purification method based on adopting ceramic GP-type membranes, and then pasteurization at the temperature of 740C for the duration of 15 seconds. Adopting both of these processes allows achieving at least two-week expiry date during storage in the temperature of up to 80C.

Microfiltration step by step

The microfiltration process is based on passing milk through ceramic membranes with pores, the size of which does not exceed 5 micrometers. Filtering milk through such membranes allows removing bacteria and other microorganisms, spores, dead cells and other impurities at the level of 99,5%-99,9%. This guarantees the lower quantity of microorganisms and bacterial spores right at the beginning of the thermal process. Microfiltration provides the possibility of adopting a lower pasteurization temperature, which guarantees retaining the activity of the natural bacteria-static substances, which can be found in milk.

Adopting microfiltration itself for preserving of skimmed milk produces the effect in the form of reduction of the general quantity of bacteria by 99,91%, by 4 logarithmic cycles in the case of the coli group bacteria, by 3 logarithmic cycles in the case of enterococcus bacteria and total elimination of spores reducing sulphites. Adopting the post-microfiltration pasteurization process improves the reduction of the general quantity of microorganisms up to 99,99%. Ultimately, pasteurized milk with contents, properties and organoleptic qualities not unlike “cow milked” milk is produced.
