The invention is directed to a method to transport liquid milk to obtain transported liquid milk during a supply chain time of more than 10 days wherein during at least a 90% of the duration of the supply chain time the liquid milk is kept at a temperature of less than 2 C. A ship is provided in the supply chain with one or more containers for carrying between 40 and 5000 M.sup.3 liquid milk. Raw milk is subjected to a pasteurization thermal treatment to obtain processed milk for transport by the ship in the supply chain.

Disclosed are processes for preparing dry or powder dairy compositions having low lactose contents and containing polyphenol compounds. The resultant dry or powder dairy compositions can be used to form reconstituted fluid dairy products, which can have improved organoleptic properties, such as less cooked flavor, sulfur odor, and brown color.

A human milk powderization system can include a spray drying machine, a receptacle, and a container. The spray drying machine can be configured to receive liquid human milk through an inlet at a rate of about 2 milliliters per minute and to spray dry the human milk at a temperature of about 163 to 167 degrees C. to transform the liquid human milk into a powderized human milk product. The receptacle can be coupled to and configured to receive the powderized human milk product from the spray drying machine. The receptacle can be formed from one or more nonreactive materials, such as crystal. The container can be removably coupled to and configured to receive the powderized human milk product from the receptacle. The container can be configured to transport the powderized human milk product away from the system, and can be formed from one or more nonreactive materials, such as aluminum.

A device for obtaining protein-enriched fractions from human or animal milk comprises a delipidating unit for reducing a lipid content in the human or animal milk to obtain delipidated milk and a filtering unit for increasing a protein concentration of the delipidated milk to obtain the protein-enriched fraction, comprising a replaceable filter having a nominal molecular weight limit of 2 kDa or more, in particular of 5 kDa or more.

A method and device are described that reduce the amount of pathogens in a liquid and/or to mitigate the growth of pathogens. Utilizing the method or device, liquid product is subjected to an 8 Bar or greater pressure drop. The liquid product is then heated to increase its temperature by at least 10 C. while it is in the droplet phase and/or after being collected into a liquid volume.

A device for inactivating or reducing an amount of biological contaminants in human milk comprises an interior for taking in human milk to be treated in order to inactivate or reduce the amount of biological contaminants, and at least one UV lamp for irradiating the milk being in the interior in order to subject it to the treatment. The treatment is a first function of the device, wherein the device has a second function, the device being capable of fulfilling the first function at the same time as the second function, wherein the second function is one or more of milk expressing, milk collecting, milk storing, milk warming, milk feeding, milk processing and milk handling.

A method for preparation of human milk to be stored includes the steps of subjecting the human milk (M) to a treatment for inactivating or reducing an amount of biological contaminants in the human milk, freezing the human milk and forming flakes of the human milk, and collecting the frozen human milk flakes (F) in a container. This method and an according apparatus enable storing human milk for later use in a very small dose, i.e. in the form of pasteurized frozen milk flakes.

A concentrate, system and low-temperature process for preparing a shelf-stable milk concentrate that does not require ultra-high temperature thermal processing for control of the microbiology of the product is disclosed herein. The method preferably incorporates aseptic technology and the enzymatic reduction of lactose to control water activity. The method preferably includes the enzymatic conversion of the lactose in the milk to its component sugars glucose and galactose, which preferably changes the colligative properties of the concentrate, decreases the amount of free water, and reduces the osmolarity.
