An article includes a heating medium injector, a mixture flow path, and a vacuum chamber. The heating medium injector has a heating medium path connected to receive a heating medium such as steam and a product path connected to receive undenatured meat protein. The heating medium injector also includes a mixing structure and a mixture outlet. The mixing structure comprises a structure within the heating medium injector at which the heating medium path and product path merge and the mixture outlet is connected to receive material from the mixing structure. The mixture flow path defines a mixture flow path volume and is connected at one end to the mixture outlet of the heating medium injector and at the opposite end to the vacuum chamber. Undenatured meat protein is contained within the vacuum chamber outside of the mixture flow path volume.

A plant for heat treating heat-sensitive fluid foodstuffs including an infusion chamber, in which the fluid foodstuff is subjected to a heat treatment by a feeding of steam, a fluid foodstuff inlet connected to a plurality of openings at the top of the infusion chamber for creating a plurality of essentially downwardly directed separate fluid foodstuff jets. The infusion chamber has a bottom section configured to collect the fluid foodstuff from the jets. The bottom section has an outlet opening at the bottom of the infusion chamber for allowing the collected fluid foodstuff to exit the infusion chamber. The outlet opening is connected to the inlet of a pump. A cooling jacket surrounds the bottom section for cooling the wall of the bottom section, and an optical camera is mounted on the infusion chamber with an angle of view covering at least a portion of the bottom section.

A process is proposed for production of low microbial count whole milk products, in which (a1) optionally, the milk product that is to be reduced in microbial count is subjected to a first heat pretreatment in a heat exchanger, and heated to temperatures in the range from 25 to 30° C., (a2) the optionally pretreated milk product is heated to temperatures of 50 to 75° C. by direct injection of superheated steam (“direct steam injection”, DSI) and pasteurized in the course of this, and (a3) the pasteurized product is cooled by flash cooling. A similar process for production of low microbial count skimmed milk products is likewise disclosed, which, as the most important intermediate step, additionally comprises separating off the cream.

The apparatus for providing milk for a coffee maker comprises a milk container having a base container for receiving the milk and a lid disposed on the base container, and at least one tube element, wherein the respective tube element protrudes into the base container and has an inlet opening for the milk, said inlet opening being in fluid connection with an outlet opening for the milk disposed on an upper side of the lid. An elastic sealing collar surrounding the outlet opening is disposed at the outlet opening. A docking system for docking to the milk container comprises a docking piece, which can be brought into a top position and a bottom position, wherein the docking piece has at least one opening for receiving the milk on an underside. If the docking piece is in the top position, the docking piece has no contact with the sealing collar and the sealing collar is shaped such that at least one section of the sealing collar protrudes upward above the respective outlet opening. If the docking position is in the bottom position, the underside of the docking piece is pressed against the sealing collar such that the sealing collar is compressed in the vertical direction and rests in a fluid-tight manner against the docking piece along a closed curve enclosing the particular opening.

The invention concerns a process for the treatment of heat-sensative fluid food products (P) in a UHT system (1), particularly dairy such as milk, cream, milk protein concentrate. The invention has the task, in a UHT system whose basic structure using an infusion chamber is described in [4], of ensuring an equal and constant dwell time as well as an equal and constant temperature trend for the entire treated food product downstream of an outlet of a mechanism in which the food product is subjected to direct heating by the introduction of steam, and to minimize fouling during heat maintenance of the food product in this area. This is achieved using process technology in that: The heated food product (P*) upstream of its heat main undergoes a predetermined pressure increase (Δp) at a predetermined, unchanging location, and The pressure level upstream of the location before the relief lies above the pressure upstream of the location before the pressure increase (Δp) (FIG. 1).

Processes for producing dairy products having lower levels of neutral lipids, and/or higher levels of polar lipids, by extraction using near critical carbon dioxide or dimethyl ether. These products may be used as ingredients in infant formulas. Infant formulas containing beta-serum are also claimed. “Beta-serum” means an aqueous dairy ingredient separated from dairy streams containing greater than 60% fat which have been through phase inversion from an oil-in- water to a water-in-oil emulsion, such as the serum produced during the production of butter oil.
