  • Process for solubilizing FD and C Red #3 under acidic conditions and composition
    Patent number: 4477474
    Abstract: FD&C Red #3 is solubilized under acidic conditions to provide a substantially cloud-free and precipitate-free product by dispersing the Red #3 in a solvent having a pH above about 4.5, fixing the Red #3 with a substrate, and solubilizing the fixed Red #3 into an aqueous solution in the presence of an amount of gelatin and for a period of time effective to stabilize the Red #3 in an aqueous solution below the pH of about 4.5, and adjusting the pH of the aqueous solution below about 4.5.
    Type: Grant
    Filed: August 20, 1979
    Date of Patent: October 16, 1984
    Assignee: General Foods Corporation
    Inventors: Joseph J. Saladini, John V. Parnell, III, Wayne L. Steensen, Harry H. Topalian
  • Stabilized dressing products
    Patent number: 4352832
    Abstract: Dressing products which are bacteriologically-stable at room temperature and which possess a pH of at least 4.2 are prepared utilizing a relatively low level of acetic acid in combination with soluble buffering salts such as sodium acetate and/or sodium citrate. The acetic acid level of the dressing product wil be from about 0.2% to 4.0% by weight of the aqueous phase contained in the composition and the buffer salt level will be from about 0.4% to 3.0% by weight of the aqueous phase.
