Milk fat fractions (olein and stearin)

Milk fat fractions (olein and stearin)

Olein and stearin milk fat fractions with varying solid fat contents (SFI/SFC) obtained in a purely physical process. Available as recombined butterfat, customized milk fat mix with defined melting points, or as individual fractions.

Product information on milk fat fractions olein and stearin  

Milk fat fractions with their very different properties from solid to liquid at room temperature can be used for a wide range of applications. The melting point is between 10–40 ° C depending on the composition of the fractionated butter fat or the type of the selected individual fraction. Butterfat is naturally lactose-free. 

Legal name:

  • Butterfat fractionated
  • Milk fat product

Milk fat fractions

Made-to-measure milk fats using fat fractions olein and stearin  

At our Uelzen site, we use a rare technology that only a few other dairies in Europe have apart from us. Our fractionation facility separates pure concentrated butter fat into its individual milk fat fractions in a purely physical process. First, the higher melting stearins are separated from the lower melting oleins. Depending on the temperature control and the number of repetitions of the fractionation process, we receive a large number of individual milk fat fractions that have different properties.

By recombination, these can be processed back into butter products with precisely defined physical properties. These include e.g. recombined butter as laminating butter plates with a higher melting point than normal premium German butter, frying creams with a great butter taste that are liquid at room temperature and can be dosed from the bottle or spreadable fats with good spreadability. With the help of another special technology, we can also produce decolorized white butterfat.

Uelzena Ingredients is not only a specialist in milk fats. We produce a variety of milk ingredients for professional processors: milk powder at the Neumünster and Uelzen sites, butter and cheese at the Bismark site, and sweetened condensed milk and milk products at the Warmsen site. At all our production sites, we produce ingredients for many well-known branded companies with sustainably produced milk from the surrounding region.
