Abstract: The present invention includes a method to produce immune-active milk products from raw milk. The method includes the steps of separating a raw milk composition into a nonfat milk fraction and a fat fraction, followed by UV-C pasteurization of the nonfat milk fraction to yield the immune-active milk product. Optionally, a composition comprising milk fat globule membrane components is added to the nonfat milk fraction either prior to or subsequent to the UV-C pasteurization step. Optionally, the nonfat milk fraction is treated with lactase to hydrolyze the lactose. The method can also optionally include a step of low-temperature drying of the immune-active milk composition, or alternatively ultrafiltration and/or diafiltration can be used to produce a milk protein concentrate as the immune-active milk products. The immune-active milk products obtained by the methods of the invention can be used to reduce, prevent or treat immune dysfunctions.

Abstract: A system for treating edible fluids under high pressure to reduce microorganisms. The system comprises a high pressure housing having an interior chamber containing two parallel flexible bladders adapted to hold the fluid to be treated under high pressure within the confines of the chamber. A pressurizing fluid fills the interior chamber outside the bladders. When one bladder is filled the other bladder is collapsed. In operation pressure is exerted throughout the interior chamber by means of the pressurizing fluid for a period sufficient to reduce microorganisms in the fluid within the filled bladder. Pressure will be released and the collapsed bladder will then be filled with an edible fluid causing treated fluid to be removed from the first bladder due to expansion caused by the filling of the second bladder such that the first bladder is collapsed. The process can then be repeated.
