Patents by Inventor Daniel K. Tang

Daniel K. Tang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5234503
    Abstract: An integrated process is disclosed which produces both crystalline fructose and a liquid-phase sweetener such as High Fructose Corn Syrup from a feed stream comprising dextrose. A portion of the dextrose in the feed stream is isomerized to fructose and the resulting dextrose/fructose stream is fractionated to produce a high fructose stream. A portion of the fructose in the high fructose stream is crystallized out and the mother liquor remaining after crystallization is blended with dextrose-containing streams to produce the liquid-phase sweetener.
    Type: Grant
    Filed: August 20, 1991
    Date of Patent: August 10, 1993
    Assignee: A.E. Saley Manufacturing Co.
    Inventors: Donald W. Lillard, Jr., Robert V. Schanefelt, Daniel K. Tang, Gary A. Day, Francis M. Mallee, Lawrence R. Schwab, Larry W. Peckous

  • Patent number: 4435438
    Abstract: Vegetable proteins may be converted into isolates which are useful for preparing imitation cheese products. These unique isolates are characterized in general as: having an NSI of at least 90, having not been subjected to enzymatic or chemical hydrolysis, forming an insoluble gel when reconstituted in water at a 15% by weight protein isolate concentration and heated to 85.degree. C. for 30 minutes, and yielding a melt value of at least 15 cm.sup.2. The isolates are prepared under conditions which precondition the protein molecules so that they may be converted, upon heat treatment, into protein aggregates which simulate the hydrocolloidal attributes of caseinate. The heat treatment causes restructuring of the proteinaceous molecules into large molecular weight aggregates.
