The invention relates to a machine for making and dispensing liquid or semi-liquid food products, comprising:

at least one tank for containing the product to be processed and dispensed and having a discharge orifice for the product to be dispensed;

at least one dispensing tap comprising:

an external conduit having an inlet orifice which is connected, in use, to the discharge orifice of the containment tank, a product release orifice and a product recirculation orifice,

a tubular duct having formed in it a first internal cavity which is provided with at least one radial opening.

The method for treating milk or a plant-based beverage comprises creating a database containing associations between combinations of values of content by weight of proteins and carbohydrates of the milk or plant-based beverage to be treated and corresponding values of at least one treatment parameter for the milk or plant-based beverage; acquiring the content by weight of proteins and carbohydrates of the milk or plant-based beverage to be treated; and treating the milk or plant-based beverage with the value of the at least one treatment parameter corresponding in the database to the acquired values of the content by weight of proteins and carbohydrates.

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.
