Preconcentration and analysis of trace volatile carbonyl compounds.
We describe a preconcentration device that may be suitable for quantitative analysis of trace volatile ketones and aldehydes in ambient air as well as in human breath. The approach is based on microreactor chips fabricated from silicon wafers. The microreactors have thousands of micropillars in microfluidic channels for uniformly distributing a gaseous sample flowing through the chips. The surf...
متن کاملVolatile Compounds of Dry Bean Seed {phaseolus Vulgaris L.)
Volatile compounds of uncooked dry bean {Phaseolus vulgaris L.) cultivars representing 3 market classes (black, dark red kidney and pinto) grown in 2005 were isolated with headspace solid phase microextraction (HS-SPME), and analyzed with gas chromatography mass spectrometry (GCMS). A total of 62 volatiles consisting of aromatic hydrocarbons, aldehydes, alkanes, alcohols and ketones represented...
متن کاملVolatile compounds and sensorial traits of "Toscano" dry-cured ham
The aims of this study were to evaluate the effect of seasoning time on aromatic profiles and to describe the sensorial profile of “Toscano” dry-cured ham. At this aim ten hams, cured according to the rule of “Toscano” PDO label, were sampled at the begin of seasoning and at 1, 3, 6 and 12 months. The samples of muscular tissue were submitted to volatile compounds analysis by SPME-GC/MS. At the...
متن کاملProtocol for collection and HPLC analysis of volatile carbonyl compounds in breath.
This noninvasive method for collection and analysis of a wide range of aldehydes and ketones in human breath may enable assessment of lipid peroxidation and metabolic status in vivo. Breath samples are drawn through silica cartridges impregnated with 2,4-dinitrophenylhydrazine, which traps carbonyls as their hydrazone derivatives. The hydrazone derivatives are eluted from the cartridges with ac...
متن کاملCorrelating volatile compounds, sensory attributes, and quality parameters in stored fresh-cut cantaloupe.
Changes in post-cutting volatiles, quality, and sensory attributes during fresh-cut storage (4 degrees C) of cantaloupe (Cucumis melo L. var. Reticulatus, Naudin, cv. 'Sol Real') harvested at four distinct maturities (1/4-, 1/2-, 3/4-, and full-slip) were investigated after 0, 2, 5, 7, 9, 12, and 14 days in a 2-year study. Increased fruity and sweet taste attributes were negatively correlated w...
