Patent number: 4133895Abstract: Blue cheese flavored products are produced by forming a mixture of whey, food fat, salt and water, homogenizing and pasteurizing the mixture, adding lipase and Penicillium roqueforti spores to the mixture and fermenting. Alternatively, a mixture of food fat, salt and water is pasteurized and fermented with lipase and Penicillium roqueforti spores, and the resultant fermented mixture is mixed with a retentate produced by ultrafiltration of a milk product. The blue cheese flavored products have an extremely high quotient of flavor which can be blended with other foods to impart a blue cheese flavor.Type: GrantFiled: September 10, 1974Date of Patent: January 9, 1979Assignee: Cornell Research Foundation, Inc.Inventors: Frank V.

Patent number: 4016250Abstract: Method for the determination of the hormone human chorionic gonadotropin (HCG), luteinizing hormone (LH), prolactin (PRL) and HCG-like material in an aqueous sample comprising contacting a highly specific receptor for these hormones with an aqueous sample to be tested, providing a means of indicating whether binding has taken place between the receptor and hormone possibly contained in the sample and observing the indicating means to determine the presence of the hormone in the sample. PRL may be determined separately or simultaneously with the HCG and LH. The receptor is a plasma membrane extract from the corpus luteum of an animal which possesses the receptor for HCG, LH, PRL and HCG-like material. Radioassay indicating means are preferred, according to which competitive protein binding between radioisotopically labeled hormone and hormone present in the sample is radiologically determined. The method has particular application to the determination to pregnancy in the human female.Type: GrantFiled: November 11, 1974Date of Patent: April 5, 1977Assignee: Cornell Research Foundation, Inc.Inventor: Brij B.

Patent number: 3997298Abstract: Liquid chromatography-mass spectrometer apparatus and method are disclosed for analyzing the components of a complex mixture, characterized in that at least a portion of the eluted effluent from the liquid column is continuously introduced directly into the ionization chamber of a chemical ionization mass spectrometer for detection of the eluted sample components. Use is made of restricted capillary tube means for introducing the complex mixture directly into the chemical ionization ion source chamber, and diffusion pump and cryogenic pump means for obtaining the desired vacuum in the ion source chamber. The solvent is used as the agent necessary for chemical ionization, thereby making it unnecessary to remove all of the solvent before introducing the sample into the analyzer. Mass spectra is taken either on a repetitive basis, or the instrument is operable to monitor the total abundance of peaks other than those resulting from the solvent.Type: GrantFiled: February 27, 1975Date of Patent: December 14, 1976Assignee: Cornell Research Foundation, Inc.Inventors: Fred W.

Patent number: 3973042Abstract: A method for producing blue cheese from pasteurized or heat treated milk, characterized by the addition to the cheese curds from which the whey has been drained, of a mixture of lipase, a Penicillium mold spore species, and salt. The Penicillium species may include Penicillium roqueforti or Penicillium glaucum, and the lipase is preferably a microbial lipase formed from Aspergilli ssp., Penicillium ssp. or Rhizopus ssp., or suitable animal lipase sources. The resultant cheese product is imparted with the appropriate blue cheese flavor with required rancidity in a greatly shortened period of time (i.e., about 2 to 4 months).Type: GrantFiled: May 10, 1974Date of Patent: August 3, 1976Assignee: Cornell Research Foundation, Inc.Inventors: Frank V.

Patent number: 3959022Abstract: An improved method is disclosed for producing a solid sodium-beta-alumina electrolyte, characterized by the step of mixing the sodium-beta-alumina powder -- prior to sintering -- with a sodium-aluminum oxide additive in which the atom ratio of sodium to aluminum is 0.54. Consequently, the temperature to which the resulting mixture must be heated to achieve sintering is greatly lowered (i.e., to between 1600.degree. C. and 1700.degree. C) by the presence of a reactive liquid phase, and the resulting sintered product has a greater density and a lower resistivity, and undesirable abnormal grain growth is avoided.Type: GrantFiled: July 9, 1975Date of Patent: May 25, 1976Assignee: Cornell Research Foundation, Inc.Inventors: Lutgard C.
