- Chemical scent constituents in the urine of the red fox (Vulpes vulpes L
- Chemical scent constituents in the urine of the red fox (Vulpes vulpes L.) during the winter season. Jorgenson, J. W.; Novotny, M.; Carmack, M.; Copland, G. B.; Wilson, S. R.; Katona, S.; Whitten, W. K. (Dep. Chem., Indiana Univ., Bloomington, Indiana, USA). Science, 199(4330), 796-8 (English) 1978. CODEN: SCIEAS. ISSN: 0036-8075. DOCUMENT TYPE: Journal CA Section: 13 (Mammalian Biochemistry) Four volatile chem. compds. (D3-isopentenyl Me sulfide, 2-phenylethyl Me sulfide, 6-methyl-D5-hepten-2-one, and trans-geranylacetone) were identified as apparently unique constituents in urines of red foxes (both sexes) during the winter season when mating occurs. Quinaldine was found only in male fox urine. 4-Heptanone, benzaldehyde, and acetophenone were found in other species also. Some or all of these compds. may function in olfactory communication in the red fox.
- Determining volatile extractives from microwave susceptor food packaging
- Determining volatile extractives from microwave susceptor food packaging. Rose, William P. (West. Res. Lab., Natl. Food Process. Assoc., Dublin, CA 94568, USA). ACS Symp. Ser., 473(Food Packag. Interact. 2), 67-78 (English) 1991. CODEN: ACSMC8. ISSN: 0097-6156. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) A method developed for the detn. of volatile extractives from microwave susceptor-contg. food packaging consists of a headspace sampling technique followed by gas-chromatog. with flame ionization or mass spectroscopy detection. A portion of the package contg. the microwave susceptor is subjected to microwave cooking under simulated use conditions. An aliquot of the headspace gases are then introduced into a gas chromatograph for the detn. and identification of individual compds. 4-Heptanone was used as an internal std. Susceptor packages representing a popcorn bag and a pizza package were fortified with 8 compds. representing a range of polarities. Recoveries of these compds. were 22-98% with relative std. deviations of 3-24%. Compds. identified by gas chromatog./mass spectroscopy in microwave susceptor packaging representative of the packaging found in the marketplace had mol. wts. of 32-200. The b.ps. of these compds. were 21-216°.
