Exosome purification methods involve use of a whey composition as an exosome source. Exosomes are isolated by subjecting the whey composition to a first ultrafiltration, which yields a first permeate and a first retentate. The first retentate may then be subjected to a second ultrafiltration, yielding a second permeate and a second retentate. During the second ultrafiltration, the first retentate may be treated with carbon dioxide. The second retentate may then be subjected to a third ultrafiltration, yielding a third permeate and a third retentate. The third permeate may then be optionally dried to yield an exosome powder.

A milk frothing apparatus which includes a steam probe; a jug and jug support; a sensor to determine the depth of milk in a jug. The steam probe or jug support is movable preferably driven by stepper motor, to maintain the tip of the probe below the milk surface. A temperature sensor monitors the temperature of the milk in the jug. A micro controller is programmable to start the process; maintain the position of the steam probe relative to the milk surface, stop the process when the milk reaches a desired temperature and maintain records of the number of cycles and a measure of the quantity of milk treated. By using a sensor to measure the distance to the milk surface in a jug the tip of the steam probe can be maintained at the appropriate distance below the milk surface by moving the jug relative to the probe or preferably moving the probe. The process can be more precisely controlled by sensing the milk temperature and ensuring that the process is completed before the milk becomes too hot. The units may use steam generated in the espresso machine or use a designated steam boiler. The units may have multiple stations each with a jug and steam probe and associated temperature sensor. The stations may have the provision of a locking mechanism to prevent removal of the jug while the process is in progress.

The present invention relates to a pea fiber product that is at least 45 dwt. % pea fiber, preferably at least 70 dwt. %, most preferably 90 dwt. % fiber of which at least 5 dwt. % fiber is soluble, preferably 10 dwt. % is soluble, most preferably 20 dwt. % is soluble, as well as the process of making such, and the beverages, sauces, bakery, and aerated products that use such. The resultant pea fiber product is such that it has a same day viscosity of 300-1100 cp at 15 wt. % concentration and of 2150-2950 cp at 17 wt. % according to viscosity Test A run at 30 RPM; and has a 60 hour viscosity of 1420-2220 cp at 15 wt. % concentration and of 6400-7200 cp at 17 wt. % concentration according to viscosity Test A.

The present invention comprises a freeze-dried, aerated dairy or dairy-substitute composition comprising a dairy or dairy-substitute ingredient and an emulsifier and methods of using and making thereof.

Freeze-dried, aerated yogurt products that include dairy or dairy-substitute compositions and an emulsifier are disclosed, along with methods of producing and using same.

A method of making a pressurized packaged liquid beverage. The method includes filling a container including a one-way valve with a liquid beverage, sealing the container, introducing a volume of gas through the one-way valve after sealing the container, and agitating the liquid beverage inside the sealed container, When the container is opened, the liquid beverage increases in volume and separates into liquid phase and a drinkable foam phase. The method may be carried out in a sealed container including a one-way valve adapted to allow a gas to enter the first container but not exit or a circulatory agitation system according to other embodiments. Thee liquid beverage may include milk, coffee, fruit juice, or mixtures thereof, particularly mixtures of milk and coffee, and may further include a gum. The gas may be nitrous oxide.

A method for forming a modified micellar casein concentrate includes providing a volume of skim milk. The method further includes performing a first filtration process on the volume of skim milk to form a micellar casein concentrate. The method includes mixing carbon dioxide with at least a portion of the micellar casein concentrate to solubilize one or more components of the micellar casein concentrate. The method includes performing an additional filtration process on the mixture of carbon dioxide and micellar casein concentrate to remove at least a portion of the one or more solubilized components of the micellar casein concentrate to form a modified micellar casein concentrate.

A freeze-dried, aerated dairy or dairy-substitute composition comprising a dairy or dairy-substitute ingredient and an emulsifier are disclosed. Methods of using and making thereof are also disclosed.

A process for packaging pressurized beverages. The process includes mixing liquid, a solute that depresses the freezing point of the liquid, and gas. Next, the liquid-gas mixture is allowed to rest. Then, retail containers are filled with the mixture. During the mixing and filling steps of the process, the liquid-gas mixture is subjected to pressures that are higher than atmospheric pressure. Unfortunately, such pressure cannot be maintained when the container is transferred from the filling station to the sealing station causing dissolved gas to leave the liquid and foam to overflow the container during the transfer. To prevent such an overflow, prior to the transfer, the dissolved gas is put to sleep by reducing the temperature of the liquid to below 0 C. (32 F.) and optionally allowing the liquid-gas mixture to rest. The liquid beverage may include milk, coffee, tea, fruit juice, chocolate or mixtures thereof, and may include a gum.

The invention refers to a pumping and foaming device (10) comprising a mixing unit (201) where air and a foamable fluid are conveyed and pre-mixed, and a foaming unit (203) where the mixture of air and fluid is foamed; the device (10) further comprising a processing element (202) rotatable with respect to the foaming unit (203), such that the rotation of the processing element (202) sucks air and fluid by centrifugal forces into the mixing unit (201), where they are conveyed and pre-mixed, that same rotation of the processing element (202) with respect to the foaming unit (203) driving the mixture of air and fluid under a certain level of shear stress which allows the mixture to be foamed. The invention further refers to a pack (100) comprising a device (10) and a fluid container (20), and further to a machine (200) to which such a pack (100) is connectable. The invention also refers to a system (300) comprising a machine (200) and a pack (100).
