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.
A method for reducing the microbial load of a liquid or viscous composition comprising one or more bioactive molecules naturally occurring in milk, comprising the steps of:
A composition comprising bioactive molecules, the composition being obtainable by a method of reducing the microbial load of a liquid or viscous composition comprising one or more bioactive molecules naturally occurring in milk, comprising the steps of:
A pulsed electric field treated composition, which is microbiologically safe and which comprises one or more proteins naturally occurring in milk, wherein at least 30% of the respective protein is in a native form.
