Ultrafiltration ables to concentre the higher molecular components, but without applying heat or phase change.

The pressure on UF application is between 1-15 bars. The uf application on room heat to concentrate eat sensitive  molecules such as protein and starch  minimazes heat reactions like dissolubility, foam and gel forming, emulsify and getting greasy. Besides, UF is used to recycle the beneficial components. This feature of UF is mostly used in the dairy industry.
