Ultraviolet (UV) sterilization system for producing highly active liquid milk. The system uses a spiral-wound PFA tube surrounding the UV lamps to sterilize turbid milk. The tube allows full mixing of the milk as it flows. The UV dose can be adjusted by changing the milk flow rate or length of tube segments. Multiple parallel UV sterilization units can be used in parallel to scale capacity. This allows customizing the UV sterilization intensity, dose, and processing volume for milk.

The sterilizer has a fixed permeable plate inside an enclosure that can be heated to sterilization temperature. The plate has holes for liquid penetration when pressure differs. A rotating applicator box with a feeding port feeds milk onto the plate. A piston below the plate closes holes. As the box rotates, milk moves down. UV lamps sterilize milk exiting holes. A transfer plate with sloped surfaces further exposes milk to inner walls. The rotating applicator, piston, and transfer plate enable uniform sterilization by fully contacting the milk with sterilizing surfaces.

A method for producing highly active and extended shelf life milk by combining ultraviolet sterilization and microfiltration. The method involves centrifuging the milk to remove fat, followed by microfiltration to remove bacteria. The milk is then ultraviolet sterilized at room temperature with doses of 13-40 mJ/cm2. This provides extended shelf life without denaturing proteins like heat treatment does. The ultraviolet sterilization is combined with microfiltration to prevent bacterial regrowth. The ultraviolet dosage is critical for preventing spoilage without affecting protein activity. The final product has higher protein content and activity compared to pasteurized milk, and an extended shelf life of at least 20 days at refrigerated temperatures.

Pasteurizing human milk to reduce contaminants without degrading important bioactive components. The method involves exposing human milk to ultraviolet (UV) light at wavelengths of 250-270nm while applying a vortical flow to the milk. The UV inactivates contaminants like bacteria and viruses while the flow ensures uniform exposure. This prevents loss of bioactives like immune factors and enzymes compared to thermal pasteurization. The UV dose can be adjusted based on milk solids.
