Abstract: A novel method of detecting and diagnosing lung cancers by monitoring and analyzing expired lung air for the presence of selected aromatic amines, particularly aniline and ortho-toluidine, is provided.

Abstract: An apparatus for the detection of odor has a dielectric sensor having a dielectric potential responsive to absorbed odor molecules, carrier gas flow for directing a substantially uniform flow of carrier gas into contact with the sensor and a detector for detecting the dielectric potential of the sensor. In accordance with certain preferred embodiments, the sensor is at least partially permeable to the flow of the carrier gas. Methods for detection of odors employing apparatus of this invention are also disclosed. Thus, in accordance with a preferred embodiment, known and unknown samples are entrained into the carrier gas for contact with the dielectric sensor. A curve of the dielectric potential of the sensor taken over a period of time for each of the samples is prepared and the curves compared to determine the identity and concentration of the odors.

Abstract: Novel odor-flavor materials and methods for producing the same are disclosed comprising a mixture of various gamma-lactones. In the preferred embodiment, a member of the genus Pityrosporum is cultured on a culture medium and is stimulated to produce a gamma-lactone containing flavor-fragrance mixture through its incubation with a lipid rich precursor. The preferred species for use in producing these gamma-lactone containing materials are P. canis, P. pachydermatis, P. orbiculare and P. ovale. The preferred lipid-rich materials include triolein, sebum, lecithin, oleic acid, and SAB with human sebum, and Tween-80. The resulting gamma-lactone rich products comprise the following lactones: gamma-hexa, gamma-hepta, gamma-octa, gamma-nona, gamma-deca, gamma-undeca, and in the case of P. canis, gamma-dodecalactone. The resultant flavor-fragrance product is all natural, exhibiting extremely pleasing taste and/or flavor characteristics.

Abstract: A novel method of detecting and diagnosing Pseudomonas aeruginosa infections by monitoring sample headspace concentrations of selected methyl ketones, particularly 2-nonanone and 2-undecanone. In an alternate embodiment, such diagnosis may be made by monitoring the headspace concentration of methyl mercaptan to diagnose the extent of a Pseudomonas aeruginosa infection. Expeditious methods for increasing such concentrations are also disclosed which include additions of selected nutrients to incubated sample mixtures.
