The present invention provides aeration methods using spherical gas bubbles having a size on the order of 0.1 to 100 microns in size. A device of the invention for producing a monodispersion of bubbles includes a source of a stream of gas which is forced through a liquid held under pressure in a pressure chamber with an exit opening therein. The stream of gas surrounded by the liquid in the pressure chamber flows out of an exit orifice of the chamber into a liquid thereby creating a monodispersion of bubbles with substantially uniform diameter. The bubbles are small in size and produced with a relatively small amount of energy relative to comparable systems. Applications of the aeration technology range from oxygenating sewage with monodispersions of bubbles to oxygenation of water for fish maintenance.
A monodispersion of bubbles in a food, comprising a beverage and at least about one thousand bubbles, wherein the bubbles have a diameter in a range of from about 0.1 micron to about 100 microns and wherein the dispersion is characterized by substantially all the bubbles having approximately the same diameter with a deviation in diameter of about ±3%.
A monodispersion of bubbles in a beverage, comprising a beverage and at least about one thousand bubbles, wherein the bubbles have a diameter in a range of from about 0.1 micron to about 100 microns and wherein the dispersion is characterized by substantially all the bubbles having approximately the same diameter with a deviation in diameter of about ±3%, wherein said monodispersion is formed by a process comprising the following steps:
A beverage mixture comprising diffused components, wherein said components are diffused into the beverage mixture by a process comprising the following steps:
A liquid beverage comprising a monodispersion of bubbles, wherein said monodispersion comprises at least about one thousand bubbles, wherein the bubbles have a diameter in a range of from about 0.1 micron to about 100 microns and wherein substantially all the bubbles have approximately the same diameter with a deviation in diameter wherein the bubbles are diffused into a liquid by a process comprising the following steps:
