Abstract: The invention is directed to a cream cheese-like product where non-casein protein replaces casein protein and a method for making such product. More specifically, the invention is directed to a process which is effective for making a cream cheese-like product substantially free of casein, wherein the process comprises: mixing (1) proteins other than milk caseins, (2) fat such as butter fat or other food grade fat, and (3) water to form a mixture; subjecting the mixture to a first homogenization to form a protein matrix stabilized emulsion system; heating the protein matrix stabilized emulsion system to a temperature effective to denature the proteins to form a denatured protein matrix stabilized emulsion; adjusting the pH of the denatured protein matrix stabilized emulsion to about 4 to about 6; subjecting the pH-adjusted emulsion to a second homogenization to form the cream cheese-like product; and packaging the cream cheese-like product. Optional ingredients such as stabilizers (e.g., gums), other emulsifiers, salts, coloring, and flavorings can be added to the mixture or to the emulsion (i.e., prior to the first or the second homogenization step).

Abstract: The present invention provides a wide-sense, non-blocking WDM cross-connect that utilizes a relatively small number of wavelength interchangers. The cross-connect of the present invention comprises first, second and third fabrics and one or more wavelength interchangers that interconnect the first and second fabrics.  Demands that require a change in wavelength are routed through the first fabric, through one or more of the wavelength interchangers, and through the second fabric. Demands that do not require a change in wavelength are only routed through the third fabric. A  routing algorithm is utilized to ensure that any sequence of connection requests and withdrawals can be routed without disturbing any currently routed requests.
