Metodo para reducir la carga microbiana de una composición liquida o viscosa que comprende someter dicha composicion a un tratamiento del campo electrico pulsado (pef); composicion que comprende moleculas bioactivas; y composicion tratada con campo electrico.

摘要

The present invention addresses the problem of inactivation of bioactive components in milk during pasteurization for preservation. The invention discloses a method of pulsed electric field (PEF) treatment of whole milk, skimmed milk, semi-skimmed milk or whey, or other liquid compositions comprising milk components or fractions. The invention is based on the finding that by selecting one or more specific process parameters, such as the PEF treatment chamber design, the specific energy applied, the field strength, pulse type, start temperature, it is possible to effectively eliminate microorganisms from the composition while conserving the activity of bioactive components in the composition.
