    Notes: Volatile compounds from 2 samples of aqueous soy-protein isolates (SPI) (7%) were analyzed using both static and dynamic headspace methods. Based on dynamic headspace analyses, the most powerful odorants were (1) dimethyl trisulfide, (2) methanethiol, (3) hexanal, (4) an unidentified charred, sweaty feet-like odor, (5) 2-pentyl furan, (6) 2,3-butadione, and (7) an unknown burnt-like odor. The most powerful odorants by static headspace analyses were (1) dimethyl trisulfide, (2) hexanal, (3) methanethiol, and (4) 2-pentyl furan. Using deuterium labeled DMTS as an internal standard, DMTS was quantified at 60.1 and 45.5 ppb in the SPIs. This corresponds to odor values of 6014 and 4554, respectively. Using a cool, on-column technique, direct injection of concentrated-headspace volatiles and solvent-recovered volatiles with an internal standard of d6-DMTS detected both methanethiol and DMTS at similar levels as with the traditional injection methods.

    Compounds Contributing to the Odor of Aqueous Slurries of Soy Protein Concentrate (2001)

    Notes: : Gas chromatography olfactometry/mass spectrometry (GCO/MS) studies on static and concentrated headspace of the aqueous slurries from soy protein concentrate (SPC) revealed acetaldehyde, methanethiol, hexanal, dimethyl trisulfide (DMTS), and 2-pentyl furan as the most odorous volatiles. Further aroma extract dilution analysis (AEDA) of the volatile extracts identified the following as the odorous substances: hexanal, 2-heptanone, octanal, 2-octanone, 1-octen-3-one, DMTS, 3-octen-2-one, 2-decanone, benzaldehyde, 2-pentyl pyridine and trans, trans-2,4- nonadienal, along with several unidentified odorants. Methanethiol and acetaldehyde, which have low boiling points, were not detected by AEDA, however. This is the first time that acetaldehyde, methanethiol, and dimethyl trisulfide have been identified as primary odorants in SPC.

    Compounds Contributing to the “Beany” Odor of Aqueous Solutions of Soy Protein Isolates (1999)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Using gas chromatography/olfactometry (GCO), major odors from the headspace of aqueous solutions of soy protein isolates were evaluated. Many corresponding odorants were identified by correlating GCO with GC/mass spectrometry (MS) on two separate stationary phases followed by comparing retention times, mass spectra, odor descriptions and odor intensities with authentic standards. Based on aroma extract dilution analyses, the most powerful odorants (strongest and most volatile first) were (1) dimethyl trisulfide, (2) trans,trans-2,4- decadienal, (3) an unidentified burnt soy sauce-like odor, (4) 2-pentyl pyridine, (5) trans,trans-2,4-nonadienal, (6) hexanal, (7) an unidentified charred sweaty feet-like odor, (8) acetophenone, and (9) 1-octen-3-one. This is the first reported occurrence of dimethyl trisulfide in soy protein isolates.

    Factors Influencing the Occurrence of Methanethiol in Aqueous Slurries of Soy Protein Concentrates (2003)

    Notes: :Aqueous slurries of 6 commercial soy protein concentrate (SPC) contained from 9.8 to 21.7 ppb methanethiol, which corresponds to odor values (in water) of 49 to 108. Effects of temperature (5.5, 24, and 65°C), pH (4.8,6.6, and 9.0), transition metals (FeCl3, FeCl2, and CuCl2), lipoxygenase, and EDTA on methanethiol levels in SPC slurries were investigated. Higher temperature (65°C), basic pH (9.0), transition metals, lipoxygenase, and EDTA caused significant increases in methanethiol compared with the control. CuCl2 caused greater increases in methanethiol than FeCl3 and FeCl2. In contrast, treatments with lower temperature (5.5°C) or acidic pH (4.8) resulted in lower levels of methanethiol in all commercial SPC samples examined.

    Fascial planes and compartments of the posterior abdomen: The perirenal and pararenal pathways (1990)

    Notes: Our objective was to describe the boundaries and sites of communication of the posterior peritoneal compartments in order to explain extensions of pathological processes in retroperitoneal areas. To this end we examined these distinct bilateral compartments [anterior (AP) and posterior (PP) pararenal and perirenal (P) spaces] in four bodies by CT scans, dissections, crosssections, latex injections, and light microscopy. Perirenal areas bilaterally were closed spaces which extended from the inferior surface of the diaphragm to the superior pelvic aperture (pelvic inlet) tapering superiorly and inferiorly in the shape of two cones with a common base at the midrenal area where they communicated across the median plane. The AP is a potential space on the right but contains the pancreas on the left. Each has shorter superior and inferior extensions than the corresponding PP space. Tough, often multilaminar, fasciae surrounded these spaces and limited the spread of injected latex except where vascular pathways permitted inter-compartmental spread. Computer-assisted 3-D reconstructions showed that these spaces extended potentially from the diaphragm into the pelvis. These compartments and their fasciae help explain the predictable yet restricted clinical extensions of pancreatitis, renal infections, and aortic aneurysms in the posterior abdomen.

    MOMS-02/D2 - First results and future applications (1994)
    In:  International Journal of Remote Sensing
    Details
    Publication Date: 2020-02-12
    Description: The Modular Opto-electronic Multispectral Stereo Scanner MOMS-02 experimental data acquired during the German Spacelab D2 mission will be used for a broad range of geoscientific objectives. The simultaneous acquisition of high spatial resolution, multispectral and stereo scenic data enables a real combination of thematic and topographic information, thus considerably improving the verification and interpretation of dynamic changes of the Earth"s surface by means of remote sensing. This paper gives a first assessment of the MOMS-02/D2 mission, the data quality and an overview on the planned methodological and application-oriented investigations for various test sites. On the basis of a few examples the possibilities of this system for future thematic applications is shown.
